Abstract
Background Heated tobacco products (HTPs) have been marketed as safer alternatives to conventional cigarettes, but emerging evidence suggests potential respiratory risks. We present a case of pulmonary complications associated with IQOS, a popular HTP, contributing to the growing understanding of these risks. Case description A 40-year-old chronic smoker switched to IQOS, consuming 1.5 packs per day. He presented with incidental chest radiographic abnormalities and peripheral eosinophilia. Computed tomography of chest revealed pulmonary nodules and ground glass opacities. Bronchoscopy indicated mild eosinophilia. After ruling out other causes, a lung biopsy was recommended but declined. Discontinuation of IQOS led to symptom resolution and radiographic improvement. This case adds to a limited literature on HTP-induced lung injury, with a unique presentation and favorable response to cessation. Conclusions The case highlights potential pulmonary complications and the first describing an organizing pattern of lung injury associated with IQOS use, emphasizing the importance of recognizing and discontinuing HTPs in patients with respiratory symptoms or radiographic abnormalities. Further research is needed to elucidate the mechanisms underlying the harmful effects of HTPs and inform public health policies. This case underscores the importance of monitoring and educating individuals about the potential risks of HTPs to respiratory health, especially in the context of smokers switching to these products.

Abstract
OBJECTIVE To critically assess the methodological characteristics and quality of interventional clinical trials investigating the effects of heated tobacco products (HTPs). DATA SOURCES Web of Science (Core collection and MEDLINE), Scopus, MedRxiv, ClinicalTrials.gov and ICTRP trial databases and transnational HTP manufacturer online publication libraries were searched for clinical trials on HTPs published between January 2010 and April 2022. STUDY SELECTION Interventional clinical trials of any design, in which at least one group of adult participants used a currently marketed HTP, were selected by two reviewers with good or very good agreement. DATA EXTRACTION Data relating to trial characteristics and effects of intervention on primary outcomes were extracted using a predesigned form. Risk of bias was assessed using Cochrane's Risk of Bias tool v1. DATA SYNTHESIS 40 trials were included, 29 of which were tobacco industry affiliated. Methodological characteristics, such as registration, design, setting, comparator interventions, participants, outcomes and analyses, varied between trials, though there were few significant differences between industry-affiliated and independent trials. Of the 40 trials, 33 were judged to be at high risk of bias and 6 at unclear risk of bias. Trial findings were not significantly associated with either affiliation or risk of bias. CONCLUSIONS The conduct and reporting of HTP interventional clinical trials were poor in many respects and limited to investigating effects of short-term exposure. These trials fall short of what is needed to determine whether HTPs are beneficial to public health, meaning they may not be a sound basis for tobacco control policy decisions.

Abstract
INTRODUCTION There have been rapid expansions in heated tobacco products (HTPs) outside of Japan and the Republic of Korea. In November 2018, HTPs were first introduced in Malaysia and since then, no studies have been conducted on Malaysians' use of HTPs. This study is the first to examine the prevalence of HTP use and reasons for use among Malaysian adults who smoked cigarettes. METHODS Data came from the 2020 ITC Malaysia Survey, a web-based survey of a nationally representative sample of adults who smoked (n=1047) aged 18 and older. They were asked on ever heard of, ever used, and currently using HTPs, and their reasons for using HTPs. RESULTS Overall, 25.4% (n= 324; 95% CI:22.3%-28.7%) of Malaysians who smoked reported ever used HTPs with 6.7% (n=85; 95% CI:22.3%-28.7%) were using them daily and 8.1% (n=110; 95% CI:6.4% -10.2%) were using HTPs non-daily. Most of them (57.2%) who dual use were of aged 25-39 and 97.3% were males. Among those who smoked daily, almost half (49.3%) were also using HTP daily. Among those who used HTPs daily and non-daily, curiosity (84.2%, 95% CI:78.4%-90.0%), taste (83.2%, 95% CI:77.3%-89.1%), and appealing technology (78.5%, 95% CI:71.3%-85.6%) were the most reported reasons. Among those who used HTPs daily, curiosity was the top reason (87.9%, 95% CI:78.9%-93.4%), while among non-daily, taste good was the top reason (81.9%, 95% CI:71.9%-88.8%). CONCLUSIONS The very high use of HTPs among Malaysians who smoked requires continued public health surveillance that can inform the regulation of these novel tobacco products.

Impact of heat-not-burn cigarette passive smoking on children's oxidative stress, endothelial and platelet function. ENVIRONMENTAL POLLUTION (BARKING, ESSEX : 1987) 2024; 345:123304. [PMID: 38295930 DOI: 10.1016/j.envpol.2024.123304] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/18/2023] [Revised: 12/30/2023] [Accepted: 01/03/2024] [Indexed: 02/10/2024]
Abstract
Growing global use of heat-not-burn cigarettes (HNBC) prompts investigation. Prior studies assessed HNBC's effects on cardiovascular health, revealing heightened oxidative stress, platelet activation, and endothelial dysfunction. However, limited understanding exists regarding passive smoking's impact on children exposed to HNBC. This study aims to assess levels of oxidative stress, endothelial and platelet function among children exposed to passive smoke from HNBC, traditional tobacco (TT) cigarettes and unexposed subjects. Seventy-eight children (2-18 years) were divided into three groups: HNBC passive smokers (n = 26), TT cigarette exposed (n = 26), and control (CNT) group (n = 26, unexposed). Oxidative stress was evaluated by serum NADPH oxidase-2 (NOX2) activity, assessed by soluble Nox2-derived peptide (sNOX2-dp), isoprostanes, hydrogen peroxide (H2O2) production, hydrogen break-down activity (HBA) and NO bioavailability. Endothelial function was assessed by brachial flow-mediated dilation (FMD). Platelet function was evaluated by soluble CD40 ligand (sCD40L), soluble P-selectin (sP-selectin) and thrombus formation by T-TAS analysis. Passive smoking-exposed children (both HNBC and TT) exhibited significantly increased serum sNOX2-dp, isoprostanes, H2O2, sCD40L sP-selectin and thrombus formation versus controls. Conversely, exposed children displayed reduced brachial FMD and serum NO bioavailability. No significant differences were found between children exposed to passive smoking of HNBC vs TT. Multivariable regression linked sNOX2 (standardized coefficient β: 0.284; SE: 0.040; p = 0.01) and H2O2 (standardized coefficient β: 0.243; SE: 0.0; p = 0.02) as independent predictors of FMD, and isoprostanes (standardized coefficient β:0.388; SE: 0.022; p < 0.001) and serum cotinine (standardized coefficient β:0.270; SE: 0.048; p = 0.01) with sNOX2-dp levels. Exposure to HNBC smoke heightened oxidative stress, endothelial dysfunction, platelet activation, and thrombus formation in children. Findings suggest avenues for interventions to curb childhood passive smoking exposure.

Abstract
INTRODUCTION IQOS was authorized by the U.S. Food and Drug Administration (FDA) as a modified-risk tobacco product. We conducted a pharmacokinetic study evaluating the nicotine delivery and subjective effects of IQOS use among current menthol cigarette smokers to better understand if IQOS is an acceptable cigarette alternative in light of the proposed menthol cigarette ban. AIMS AND METHODS Participants were adult smokers of >4 menthol cigarettes per day. After 14-hour nicotine abstinence, participants were provided an IQOS device and menthol heatstick to puff every 20 seconds for a total of 14 puffs. Blood samples were collected at baseline and during active use to calculate nicotine boost from baseline to peak concentration. Nicotine withdrawal symptoms were collected before and after IQOS use. In addition, a modified Product Evaluation Scale for IQOS was collected after use. RESULTS Participants (n = 8) were a mean age of 43.9 years, 63% were female, 88% identified as White, and they smoked a mean of 17.1 menthol cigarettes per day. After IQOS use, the mean nicotine boost obtained was 15.96 ng/mL (SD = 6.91) (range 9.31 to 30.55 ng/mL). Most (75%) participants reported enjoying use of the product "a lot" or greater and more than half (62.5%) reported reduced cigarette cravings. Most participants reported no side effects after use; however, two experienced dry mouth, three experienced dizziness, one experienced throat irritation, and one experienced headache. CONCLUSION We found that directed use (14 puffs) of menthol IQOS delivered a mean nicotine boost of 15.96 ng/mL which reduced craving for a cigarette. The majority of participants enjoyed use of IQOS and reported mild side effects. IMPLICATIONS Menthol IQOS delivered a sufficient dose of nicotine perceived as satisfying by menthol cigarette smokers and it reduced craving with mild side effects. Menthol IQOS has potential to serve as a less harmful alternative for menthol cigarette smokers. The availability of modified risk products like IQOS should be considered by FDA's Comprehensive Plan for Tobacco and Nicotine Regulation.

Abstract
INTRODUCTION Heated tobacco products (HTPs) are marketed as less harmful alternatives to cigarettes, but the lung cancer risk of HTPs is unknown. In the absence of epidemiological data, assessing the risks of HTPs relies on biomarker data from clinical trials. This study examined existing biomarker data to determine what it tells us about the lung cancer risk posed by HTPs. AIMS AND METHODS We identified all biomarkers of exposure and potential harm measured in HTP trials and evaluated their appropriateness based on ideal characteristics for measuring lung cancer risk and tobacco use. The effects of HTPs on the most appropriate biomarkers within cigarette smokers switched to HTPs and compared to continued cigarette smoking or cessation were synthesized. RESULTS Sixteen out of eighty-two biomarkers (7 exposure and 9 potential harm) measured in HTP trials have been associated with tobacco use and lung cancer, dose-dependently correlated with smoking, modifiable upon cessation, measured within an appropriate timeframe, and had results published. Three of the exposure biomarkers significantly improved in smokers who switched to HTPs and were not significantly different from cessation. The remaining 13 biomarkers did not improve-in some instances worsening upon switching to HTPs-or were inconsistently affected across studies. There were no appropriate data to estimate the lung cancer risk of HTPs in non-smokers. CONCLUSIONS The appropriateness of existing biomarker data in assessing lung cancer risk of HTPs, both relative to cigarettes and their absolute risk, is limited. Furthermore, findings on the most appropriate biomarkers were conflicting across studies and largely showed no improvement following a switch to HTPs. IMPLICATIONS Biomarker data are fundamental to assessing the reduced risk potential of HTPs. Our evaluation suggests much of the existing biomarker data on HTPs is inappropriate for determining the risk of lung cancer posed by HTPs. In particular, there is a paucity of data on the absolute lung cancer risk of HTPs, which could be obtained from comparisons to smokers who quit and never smokers exposed to or using HTPs. There is an urgent need for further exploration of the lung cancer risks posed by HTPs, via clinical trials and, in the long-term, confirmation of these risks via epidemiological studies. However, careful consideration should be given to biomarker selection and study design to ensure both are appropriate and will provide valuable data.

Abstract
BACKGROUND IQOS is a heated tobacco product marketed as an alternative to combustible cigarette smoking. Little is known about cigarette smokers' IQOS health risk perceptions and if these risk perceptions impact IQOS use and cigarette smoking behaviour. METHODS Adult, daily, non-treatment-seeking cigarette smokers (n=27), naïve to IQOS, were recruited from Philadelphia, Pennsylvania, USA. Participants were introduced to IQOS and then completed measures of risk perceptions. Participants were given an IQOS 2.4 holder, charger and HeatSticks, and asked to switch completely from cigarettes to IQOS for 14 days. The effects of risk perceptions on changes in IQOS use, cigarettes per day (CPD), the substitution of IQOS for cigarettes and motivation to quit smoking were evaluated. RESULTS Over the 14-day switch period, CPD significantly decreased (B=-0.18, 95% CI=-0.26 to -0.09, p<0.0001), IQOS use significantly increased (B=0.02, 95% CI=0.00 to 0.03, p=0.042), as did the percentage IQOS HeatSticks that replaced CPD (B=0.02, 95% CI=0.01 to 0.03, p=0.005). Participants who perceived IQOS as less risky than cigarettes used fewer IQOS HeatSticks per day. A lower percentage of IQOS HeatStick substitution for cigarettes was observed for participants with higher versus lower risk perceptions (B=-0.14, 95% CI=-0.28 to -0.01, p=0.042). Motivation to quit increased from a mean of 5.53 to 6.79 on the contemplation ladder from baseline to day 14 (B=1.26, 95% CI=0.54 to 1.97, p<0.001). CONCLUSIONS Smokers reduced their smoking rate and increased motivation to quit smoking while using IQOS. IQOS risk perceptions did not directly account for reductions in smoking, although they may contribute indirectly through increased IQOS use.

Abstract
We present a secondary data analysis of the raw data from the eighth Korea National Health and Nutrition Examination Survey (KNHANES). A total of 827 current smokers who responded that they had smoked >5 packs (100 cigarettes) of cigarettes in their lifetime and were currently smoking traditional cigarettes were selected. This study was conducted to identify sociodemographic, smoking-related, and health-related characteristics that influence the use of e-cigarettes in adult smokers. To examine these factors, general characteristics such as age, marital status, education level, and occupation were included in Model 1, while health-related characteristics such as the level of smoking and depression were included in Model 2. In Model 1, age, a high level of education, and working in an office were found to be significantly correlated with e-cigarette use among smokers, while age and working in the office were found to be significantly correlated with e-cigarette use in Model 2. Therefore, e-cigarette use was high among adult smokers of young ages who were office workers. Although evidence is lacking regarding its safety and use as smoking cessation aids, many smokers have been reported to use e-cigarettes as smoking cessation aids, making it necessary to provide accurate information on e-cigarettes.

Abstract
BACKGROUND Communication of the relative health risks of IQOS can attract potential consumers, aiding its commercial success. However, health-related claims need to be used cautiously to avoid inaccuracies and attracting non-smokers. We used the live webchat service on the IQOS website to identify information and claims on the relative risks of IQOS made directly to potential consumers in different countries. METHODS The study was promoted through authors' networks and conducted between 1 August and 30 November 2020. Participants collected webchat conversation responses to three queries regarding the safety of IQOS relative to cigarettes and e-cigarettes using step-by-step guidance and a predesigned form. Responses were analysed to identify health-related claims and information provided. RESULTS 70 webchat attempts were recorded across 27 countries, 54 of which (in 22 countries) were successful webchat conversations. In 48 of these, one or more claims were used to indicate IQOS is safer than cigarettes, such as IQOS is smoke free, emits less harmful substances or reduces harm. Four conversations contained statements indicating IQOS is safer than e-cigarettes. Some statements provided were contradictory. Participant age was consistently requested on accessing the website, but tobacco/nicotine use was not. Other information provided included referral to the 2020 US Food and Drug Administration Modified Risk Tobacco Product decision, IQOS or Philip Morris International web pages and claims that IQOS is not risk free nor a cessation device. CONCLUSIONS A variety of claims and information on the relative safety of IQOS were used in webchat communications. Response variation highlights that clearer regulation is needed to appropriately control corporate communications via live webchat services.

Abstract
OBJECTIVES Philip Morris has a history of aggressive marketing tactics in its global pursuit of IQOS sales, which extant literature suggests may appeal to non-smokers and young adults. This study was the first to examine point-of-sale (POS) marketing and pricing of IQOS after it entered the US market in October 2019. METHODS Trained field staff assessed 75 retail partner stores selling IQOS/HeatSticks in the Atlanta area in February-November 2020 using an IQOS-tailored, standardised assessment tool. The tool assessed store characteristics, product availability and accessibility, marketing and promotions and pricing for each store. RESULTS All stores assessed sold HeatSticks in at least one of the three flavours (tobacco, smooth menthol, fresh menthol), but did not sell the IQOS device. IQOS/HeatSticks marketing was present inside 98.5% and outside 17.3% of stores assessed. Marketing for other tobacco products was present inside 98.5% and outside 32% of stores. The average price per HeatSticks pack was US$6.40 compared with US$6.08 for Marlboro Red cigarettes. CONCLUSION Our study revealed a considerable amount of POS marketing and promotion for IQOS/HeatSticks at retail partner locations, visible to all retail consumers, including youth and non-smokers. This study was the first to examine IQOS POS marketing and promotion in the US context and findings add to the extant literature on IQOS global marketing strategies. As additional novel tobacco/nicotine products continue to enter the market, targeted monitoring of the POS marketing and promotion for these new products is warranted.

Abstract
As the availability of tobacco forms has evolved, emerging products known as heated tobacco products (HTPs) are increasingly being consumed worldwide and are claimed to be less harmful than tobacco cigarette smoking. To date, it is unknown whether Arab cigarette smokers are using or susceptible to HTPs. Therefore, this study aimed to assess the association between cigarette smoking behavior and the use of and susceptibility to HTPs in the Eastern Mediterranean region. Arab cigarette smokers (n = 628) from Saudi Arabia, Egypt, Kuwait, and Yemen were recruited using a convenience sampling technique. A cross-sectional survey comprised questions related to sociodemographic characteristics, cigarette smoking behavior characteristics (quitting attempts and desire to quit cigarette smoking, nicotine dependence, and consideration of switching to nicotine products with reduced health risks), and awareness of, use of, and susceptibility to use of HTPs. Descriptive and logistic regression models were used for analysis. The participants indicated a high frequency of past quitting attempts and a desire to quit smoking cigarettes. They were also considering switching to a nicotine product with reduced health risks. However, their awareness of HTPs was relatively low (24.2%), and the proportion of participants who had ever used HTPs or were currently using them was quite low as well (10.7% and 5.0%, respectively). A history of quit attempts was associated with more likely lifetime use of HTPs (adjusted odds ratio [AOR] = 2.63, 95% confidence interval [CI] [1.21-5.71]). Nicotine-dependent cigarette smokers were more likely to be susceptible to HTP use (AOR = 1.12, 95% CI [1.01-1.24]). Moreover, those who would consider switching to a product that provided nicotine and could reduce health risks by 99% were more likely to be susceptible to using HTPs (AOR = 2.17, 95% CI [1.05-4.51]). Awareness of HTPs is relatively low among Arab cigarette smokers. Attempts to quit cigarette smoking, nicotine dependence, and the consideration of switching to a product that delivers nicotine with reduced health risks were significantly associated with using HTPs. The findings of this study provide potential for evidence-based treatment for smokers and will help prevent the use of tobacco industry tactics in marketing HTPs.

Nicotine Tob Res 2023; 25:1014-1021. [PMID: 36205373 PMCID: PMC10077945 DOI: 10.1093/ntr/ntac228] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2022] [Revised: 09/16/2022] [Accepted: 10/06/2022] [Indexed: 11/13/2022]
Abstract
INTRODUCTION Heated tobacco products (HTPs) share similar characteristics as combustible cigarettes and electronic nicotine delivery systems (ENDS) and thus may serve as cues for smoking and vaping. While HTP familiarity is low in the United States, HTPs may be perceived as a less harmful alternative to cigarettes. AIMS AND METHODS The present study examined if visual exposure to HTP use influenced cigarette and e-cigarette craving in a large national sample of adults with varied smoking patterns. Current, former, and never cigarette smokers (N = 515; Mage = 40) were recruited from online crowd-sourcing panels throughout the United States from January to April 2020. Participants completed surveys before and after watching a video depicting the use of an HTP, cigarette, or bottled water. Main outcomes were changes in cigarette craving after exposure to the video cue. Secondary outcomes included changes in e-cigarette craving. RESULTS Relative to the water cue, the HTP and cigarette cues increased cigarette craving in current smokers. The HTP cue also increased e-cigarette craving (desire for a mod or vape pen and JUUL) across all subgroups. CONCLUSIONS Current smokers demonstrated cue reactivity to the use of an HTP as they reported increases in both cigarette and e-cigarette craving after exposure. All smoking groups reported e-cigarette reactivity to the HTP cue. As HTPs gain traction globally, it is crucial to consider how their use may influence active users and passive viewers to inform future health policies. IMPLICATIONS Noncombustible nicotine delivery systems are known cues for cigarette smoking and e-cigarette vaping, and this study examined whether relatively novel heated tobacco products (HTPs) may also act as a smoking or vaping cue in adults across varied smoking backgrounds. Results showed that passive exposure to HTP use increased desire for both a cigarette and an e-cigarette in current smokers and also increased desire for an e-cigarette in former and nonsmokers. Thus given its similarity to smoking and vaping, HTP use may affect passive observers and could play a role in perpetuating the dual use of cigarettes and vape products.

Abstract
An estimated 65 million people worldwide have moderate or severe chronic obstructive pulmonary disease (COPD), an umbrella term used to describe a group of progressive lung diseases that obstruct airflow such as emphysema and chronic bronchitis. Smoking contributes to an estimated 90% of COPD cases, as the harmful chemicals produced during tobacco combustion damage the lungs and airways. Although smoking cessation is the only intervention shown to improve COPD prognosis in smokers, many patients who try to quit continue to smoke. The continued use of conventional cigarettes exacerbates COPD symptoms, and globally more than 3 million people die from the disease every year. The last two decades have seen the introduction of combustion-free nicotine delivery alternatives that produce significantly lower levels of the harmful components in cigarette smoke, and researchers have begun to assess the impact of switching from cigarettes to these products. Several studies have examined how patients with COPD use e-cigarettes as assistance for quitting, but few have examined how heated tobacco products (HTP) may reduce risk. This narrative review summarises results from pre-clinical, clinical, and real-world evidence studies showing possible harm reduction benefits for patients with COPD who switch to HTPs rather than continuing to smoke cigarettes. Epidemiological studies, real-world data analyses, and randomised clinical trials must be conducted to determine whether switching from cigarettes to HTPs can improve health outcomes in patients with COPD who would otherwise continue to smoke combustible cigarettes.

Abstract
Understanding students' attitudes toward smoking and tobacco products is essential for effective smoking prevention interventions. This questionnaire-based cross-sectional survey aims to determine the prevalence of use and knowledge about cigarettes, heated tobacco products, and electronic cigarettes and their harmful effects among university students. The survey was conducted using a self-administered online questionnaire among 1184 students. Questions were related to the respondents' demographic characteristics, tobacco use patterns, and opinions about exposure to health warnings and tobacco product advertising messages. Data were analyzed using descriptive statistics and generalized linear regression analysis. The results showed that 30.2% of the students use tobacco products (74.5% smoked conventional cigarettes; 7.9% used electronic cigarettes; and 17.6% used heated tobacco products). The median (interquartile range) score of the students' knowledge (maximum = 27) was 16 (12-22). The results showed that students from technical, social, humanities, natural, and biotechnology scientific programs had lower levels of knowledge about tobacco products and their harmful effects than biomedical students (p ≤ 0.001). In addition, past and current use of tobacco products was significantly associated with higher overall knowledge of tobacco products and their harmful effects (adjusted odds ratio (OR) 1.90, % confidence interval (CI) 1.09-3.31, p = 0.023; OR 1.41, CI 1.08-1.84, p = 0.011). The research findings confirm the lack of knowledge and misconceptions about the harmful effects associated with tobacco product use. They also emphasize the need for better prevention and awareness of the harmful effects of smoking on human health.

Romanian young adult perceptions on using heated tobacco products following exposure to direct marketing methods. NPJ Prim Care Respir Med 2023; 33:8.

Abstract
Heated tobacco products have a rapid uptake, especially among young people, mostly where advertising is unregulated, as is the case in Romania. This qualitative study explores the influence of direct marketing methods of heated tobacco products on young people, their perception and behaviour towards smoking. We have carried out 19 interviews with smokers of heated tobacco products (HTPs) or/and combustible cigarettes (CCs) or non-smokers (NS), aged 18-26. Using the thematic analysis, we have identified three overarching themes: (1) people, places, and subjects of marketing, (2) engagement with risk narratives and (3) social body, family bonds, and autonomous self. Even if most of the participants have been exposed to a mix of marketing methods, they did not acknowledge the influence that marketing has on their decision to experience smoking. Young adults' decision to use heated tobacco products seems to be influenced by a cluster of reasons: overcoming the legislation gap which prohibits indoor use of combustible cigarettes but not heated tobacco products; the attractivity of the product (novelty, inviting appearance, technological appeal and price) and presumed less damaging effects on health.

Abstract
BACKGROUND AND AIMS Tobacco and nicotine marketplaces have diversified over the past decade, including with the introduction of heated tobacco products (HTPs), such as the brand IQOS. HTPs typically heat tobacco to generate an aerosol that is inhaled. HTP nomenclature is lacking, and how HTP users define and identify themselves remains understudied. Research in this area is important because language can construct identity, and identity can shape behaviour. This study aimed to explore users' language choice when describing IQOS use, and how language relates to user identity. METHODS Qualitative interviews in London, United Kingdom, with 30 adult current and former IQOS users. Analyses were guided by Iterative Categorization. RESULTS Overall, participants expressed confusion and a lack of suitable terminology for how to describe IQOS use. Verbs such as heating and IQOSing were rarely endorsed. Most often, participants reverted to smoking when describing IQOS use and commonly referred to HEETS (tobacco sticks) as cigarettes. Yet the lack of combustion, electronic device, cleaner experience and perceived reductions in health risks led some to frame IQOS as distinct from smoking. Vaping was generally considered inappropriate for describing IQOS use. Participants also manipulated language to suit their circumstances and manage their identity, whereas some IQOS users embraced the terms smoking and smoker, most were eager to distinguish between using IQOS and being labelled a smoker because of the associated negative connotations and to align with perceptions of IQOS use as a better, less harmful behaviour. Instead, when describing their identity, IQOS users more willingly identified as vapers, or ex-smokers, or created new identities (e.g. HEET user). CONCLUSIONS People who use or have used IQOS (a brand of heated tobacco product) are ambiguous about IQOS terminology. Participants in this study commonly referred to IQOS use as smoking for lack of a more suitable term, but also resisted being labelled as smokers, a choice that may influence smoking cessation. Clear terminology must be used in surveys and by healthcare professionals when asking about cigarette smoking and e-cigarette and heated tobacco product use.

Abstract
In line with the global trends, electronic cigarettes (e-cigarettes) and heated tobacco products (HTPs) have found their way to the Lebanese market. The present study aims to explore the determinants of e-cigarette and HTP use among young adults in Lebanon. Convenience and snowball sampling were used to recruit participants aged 18-30 residing in Lebanon, who were familiar with e-cigarettes products. Twenty-one consenting participants were interviewed via Zoom and the verbatim transcriptions were analyzed thematically. The outcome expectancy theory was used to categorize the results into determinants and deterrents of use. HTPs were viewed by participants as another mode of smoking. The results showed that most participants perceived e-cigarettes and HTPs to be healthier alternatives to cigarettes/waterpipes and to be used as smoking cessation tools. Both e-cigarettes and HTPs were found to be easily accessible in Lebanon; although, in the recent economic crisis, e-cigarettes have become unaffordable. More research is needed to investigate the motivations and behaviors of e-cigarette and HTP users if effective policies and regulations are to be developed and enforced. Furthermore, greater public health efforts need to be made to increase awareness of the harmful impacts of e-cigarettes and HTPs and to implement evidence-based cessation programs tailored to those modes of smoking.

Abstract
Dozens of drugs have been evaluated in recent decades for initial evidence of efficacy to aid smoking cessation (i.e. "early Phase 2" testing, according to U.S. FDA terminology), with the vast majority failing to show efficacy. Even small randomized clinical trials (RCTs), the most common early Phase 2 tests, are costly undertakings, made more unappealing by their high likelihood of failure. At the same time, another early Phase 2 approach, acute tests of drug effects on surrogate endpoints such as withdrawal or craving severity, are more practical but have little predictive clinical validity. Described here is an innovative procedure that optimally combines the validity of clinical trials with the practical advantages of surrogate endpoint studies to more efficiently determine whether or not a novel drug warrants continued clinical development. This CrEATE procedure, or Crossover Evaluation of Addiction Treatment Efficacy, does so by assessing short-term quit success in smokers highly motivated to quit when briefly treated with active drug versus placebo in a crossover design, so that quit efficacy from both conditions is compared within participants. The program to develop and evaluate CrEATE demonstrates its sensitivity to efficacy from all three FDA-approved first-line cessation medications (NRT, varenicline, bupropion), tested here as model drugs, as well as specificity in identifying lack of efficacy with a drug known to be ineffective for cessation (modafinil). CrEATE has subsequently been used to evaluate a few novel interventions, concluding they lack efficacy in increasing quit success. Future directions for the potential utility of CrEATE are provided. Implications: The ability of CrEATE to reach a Go/No Go decision more quickly and with far less cost lowers the risk of failure, meaning widespread use of the procedure should encourage the evaluation of more novel candidate drugs. With its greater efficiency, failed tests, unfortunately the most likely outcome in early Phase 2 studies, will cause less waste of resources. At the same time, CrEATE tests that indicate a novel treatment has efficacy will justify the substantial time and expense of moving forward to evaluate the drug in late Phase 2 RCTs.

Abstract
Background After the advent of heated tobacco products (HTPs) in 2017, domestic cigarette sales declined until 2019, but have increased in South Korea since 2020. This study aimed to analyze tobacco use and cessation behavior among HTP users compared with conventional cigarette (CC) users. Methods We analyzed data from the eighth Korea National Health and Nutrition Examination Survey (2019). Of 6,188 study participants, 1,181 were current tobacco product users (single, dual, and triple), including all combinations of CCs, HTPs, and electronic cigarettes (ECs). Tobacco use and cessation behaviors among single and dual users of CCs and HTPs were assessed using various categorical methods. Results In 2019, proportions of HTP use in men and women aged ≥19 years in South Korea were 8.8% and 1.5%, respectively, and those of single, dual, and triple users were 23.6%, 58.0%, and 18.4%, respectively. Dual users had more tobacco use than CC only and HTP only users (all P<0.001). Each daily user accounted for a lower percentage of attempt and preparation stages for cessation than intermittent users (all P<0.001, except for dual users). Conclusion In this study, we analyzed the differences in tobacco use and cessation behavior among CC and HTP users in various populations in South Korea. Additionally, we found that all novel tobacco product users had already experienced CCs in adulthood. Further studies that address HTP’s harmful effects in humans are necessary.

Abstract
BACKGROUND People who smoke and who face challenges trying to quit or wish to continue to smoke may benefit by switching from traditional cigarettes to noncombustible nicotine delivery alternatives, such as heated tobacco products (HTPs) and electronic cigarettes (ECs). HTPs and ECs are being increasingly used to quit smoking, but there are limited data about their effectiveness. OBJECTIVE We conducted the first randomized controlled trial comparing quit rates between HTPs and ECs among people who smoke and do not intend to quit. METHODS We conducted a 12-week randomized noninferiority switching trial to compare effectiveness, tolerability, and product satisfaction between HTPs (IQOS 2.4 Plus) and refillable ECs (JustFog Q16) among people who do not intend to quit. The cessation intervention included motivational counseling. The primary endpoint of the study was the carbon monoxide-confirmed continuous abstinence rate from week 4 to week 12 (CAR weeks 4-12). The secondary endpoints included the continuous self-reported ≥50% reduction in cigarette consumption rate (continuous reduction rate) from week 4 to week 12 (CRR weeks 4-12) and 7-day point prevalence of smoking abstinence. RESULTS A total of 211 participants completed the study. High quit rates (CAR weeks 4-12) of 39.1% (43/110) and 30.8% (33/107) were observed for IQOS-HTP and JustFog-EC, respectively. The between-group difference for the CAR weeks 4-12 was not significant (P=.20). The CRR weeks 4-12 values for IQOS-HTP and JustFog-EC were 46.4% (51/110) and 39.3% (42/107), respectively, and the between-group difference was not significant (P=.24). At week 12, the 7-day point prevalence of smoking abstinence values for IQOS-HTP and JustFog-EC were 54.5% (60/110) and 41.1% (44/107), respectively. The most frequent adverse events were cough and reduced physical fitness. Both study products elicited a moderately pleasant user experience, and the between-group difference was not significant. A clinically relevant improvement in exercise tolerance was observed after switching to the combustion-free products under investigation. Risk perception for conventional cigarettes was consistently higher than that for the combustion-free study products under investigation. CONCLUSIONS Switching to HTPs elicited a marked reduction in cigarette consumption among people who smoke and do not intend to quit, which was comparable to refillable ECs. User experience and risk perception were similar between the HTPs and ECs under investigation. HTPs may be a useful addition to the arsenal of reduced-risk alternatives for tobacco cigarettes and may contribute to smoking cessation. However, longer follow-up studies are required to confirm significant and prolonged abstinence from smoking and to determine whether our results can be generalized outside smoking cessation services offering high levels of support.

Drug Alcohol Depend 2022; 238:109569. [PMID: 35841732 DOI: 10.1016/j.drugalcdep.2022.109569] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/11/2022] [Revised: 07/06/2022] [Accepted: 07/08/2022] [Indexed: 11/03/2022]
Abstract
BACKGROUND It is unknown whether IQOS-associated decreases in cigarette craving, nicotine withdrawal, greater subjective reward, and relative reinforcing value predict subsequent switching from cigarettes to IQOS products. METHODS Nontreatment-seeking adult daily smokers (n = 33; 18-65 years old) completed a within-subject pilot study consisting of a baseline ad-lib smoking period (days 1-5), two laboratory visits (days 6-7), and a two-week period where participants switch from using cigarettes to using IQOS (days 8-21). Mixed-effect modelling estimated the percentage of baseline cigarette consumption replaced by daily IQOS HeatSticks used. Predictors of use included IQOS-associated reinforcement, subjective reward, and craving and withdrawal relief. RESULTS IQOS use alleviated cigarette abstinence-associated craving (change=-14.22, p < .001) but did not alleviate withdrawal symptoms. Smokers initially substituted IQOS for 59% of their average daily cigarette consumption, increasing to 87% by switch period end (B=0.02 [95%CI=0.01, 0.03], p = .002). Neither subjective reward of IQOS nor relief of cigarette craving and withdrawal symptoms were predictive of this change. By study end, IQOS consumption was 124% of regular cigarette consumption among participants with a low reinforcing value of cigarettes relative to IQOS (β = 0.03 [95%CI=0.00, 0.06], p = .049). In contrast, participants with a higher reinforcing value of smoking replaced 76% of their cigarettes with IQOS. CONCLUSIONS IQOS shows potential as an alternative to combustible cigarettes. However, IQOS use may result in dual-use for most smokers and increase tobacco consumption among a subgroup of smokers. These preliminary findings highlight the need for a larger investigation of the relationship between IQOS use and cigarette smoking.

Abstract
In this study, the effect of the use of heat-not-burn (HnB) products on indoor air quality (IAQ) was evaluated. To do this, the concentrations of nicotine, propylene glycol (PG), and vegetable glycerin (VG) directly emitted when using HnB products were analyzed and compared to those from conventional cigarettes. Furthermore, the levels of VOCs, aldehydes, nanoparticle, and particulate matter (PM) detected when subjects used HnB products in the exposure chamber were evaluated the effect on IAQ. As a result, the range of nicotine levels transferred by HnB products (0.8-1.2 mg cigarette-1) is lower than that by conventional cigarettes (2.4-3.6 mg cigarette-1). On the other hand, the range of VG levels emitted from HnB products (3.1-5.9 mg cigarette-1) were higher than that emitted from conventional cigarettes (0.6-3.0 mg cigarette-1). In addition, although the amount generated from HnB products was small compared to those from conventional cigarettes, various kinds of VOCs, aldehydes, nanoparticle and PM were produced, and these were confirmed to affect IAQ.

Abstract
BACKGROUND The popularity of heated tobacco products (HTPs) has been growing globally but, limited information exists on tobacco use behaviors and its impact on tobacco control. This study investigates awareness and perception of HTPs among tobacco users and whether perceptions of HTPs are associated with HTP use and intention to quit. METHODS We invited 2,000 tobacco users aged 19-65 years with countrywide representation to an online survey in November 2018. Information on general characteristics, tobacco use behaviors, awareness and perception of HTPs, and intention to quit were gathered. Multinomial logistic regression analysis and ANCOVA were used for estimation of association and comparison. RESULTS Among all tobacco users, 36.8% were classified as ever users, whereas 28.3% had used HTPs in the past 30 days, which was higher than expected. Users of liquid-based e-cigarettes (odds ratio [OR] 1.578; 95% confidence interval [CI], 1.210-2.056) and poly-product users (OR 2.029; 95% CI, 1.121-3.671) showed higher intention to quit within 1 month when compared to users of conventional cigarettes (CCs), whereas HTP users and dual product users did not. HTP users rated HTPs more favorably than CCs in terms of smoke, smell, harm, aid in quitting, design, and price than users of other products did (P-value < 0.001). CONCLUSION We find that positive perception of HTPs following strategic marketing from tobacco companies could have contributed to a greater increase in HTP use than expected in Korea. However, HTPs might not be considered substitutes for CCs for quitting tobacco use because a significant proportion of dual product users reported a lower intention to quit.

Abstract
OBJECTIVE Philip Morris International, has already introduced its heated tobacco product, IQOS, in many countries and marketed it on the grounds that it is a less harmful alternative to health. The company claims that its intention is for its brand's traditional cigarette smokers to replace these with IQOS has rarely been independently tested. METHOD Using time series data from September 2016 to June 2020, we analyze whether Heets sales have been accompanied by an improvement in the position of Philip Morris International in the market or if they have merely replaced lost sales of the rest of the brands sold by that tobacco company. RESULTS Sales of traditional cigarettes of all the brands marketed by PMI have been replaced by IQOS since the introduction of this heated tobacco product in Spain. Almost all of the variations observed in IQOS sales are due to the positioning of this product as a substitute for the range of traditional cigarettes marketed by Philip Morris International. CONCLUSIONS As there is still no consensus that HTPs are explicitly less harmful to health, health authorities must control messages suggesting improved health outcomes thanks to HTP usage when compared to traditional cigarettes. Such messages could generate a false sense of security and lead to an increase in the consumption of tobacco. In Spain Heets in a category that has a lower tax burden than the category of traditional cigarettes. Tax authorities must consider this migration and the impact this may have on tax collection.

Abstract
The popularity of heated tobacco products (HTPs) is of concern, as most users are dual users exposed to emissions of both HTPs and conventional cigarettes. Furthermore, HTPs may appeal to young people and non-smokers. This study aims to build intelligence on user experiences in order to inform policy development. We conducted five semi-structured focus group interviews with single-, dual-, and ex-users of the HTP IQOS. The discussions focused on initiation and use, experiences and perception, and knowledge and information needs. We performed a thematic analysis of the transcripts. All users smoked cigarettes and/or roll your own (RYO) tobacco before using HTP. We found that almost all users started using IQOS after being introduced to it by others. Single users successfully quit smoking cigarettes using the IQOS, liked the taste, and experienced physical benefits. Dual users experienced more satisfaction from smoking cigarettes and used the IQOS for specific occasions, such as social situations or in places with smoking bans. All IQOS users described themselves as smokers and considered using the IQOS as an alternative way of smoking. Regulators may consider providing reliable and easily accessible information and regulating points of sale, promotional activities, and product properties such as flavors and devices in order to reduce product attractiveness and discourage use.

Abstract
Background Risk perception (RP) is central to smokers’ decision to switch to smoke-free tobacco and nicotine products (TNP). This study assessed temporal trends in the health RP of a novel heated tobacco product, IQOSTM, relative to cigarettes, among current IQOSTM users. Methods The analyses included repeated cross-sectional data from online surveys in Germany (2018–19), Italy (2018–19), and Japan (2016–17, 2017–18, and 2018–19) among a random sample of current adult IQOSTM users from local registers of IQOSTM users. The health RPs of cigarettes and IQOSTM were assessed using the ABOUT™–Perceived Risk instrument, and their difference was described as the relative RP of IQOSTM to cigarettes (RPCig:IQOSTM). Results After adjustment for covariates, the relative RPCig:IQOSTM was higher in 2018 than in 2019 (0.93; standard error, 0.33; P = 0.005). This was driven by an increase in the RP of IQOSTM over time in Italy (2018: 42.6 [95% CI, 41.6–43.5]; 2019: 44.4 [43.4–45.4]) and Japan (2017: 44.0 [43.1–44.9); 2018: 45.9 [45.2–46.7]; 2019: 48.6 [47.9–49.4]), while the RP of cigarettes remained stable. Conclusions The relative RP of IQOSTM decreased over time, driven by an increase in the RP of IQOSTM, in agreement with epidemiological studies indicating a temporal reduction in the relative RP of smoke-free TNPs. Continued surveillance of the RP of novel TNPs is warranted to inform effective TNP risk communication and ensure that adults smokers who would otherwise continue to smoke understand the relative risks of novel TNPs. Risk perception is central to smokers' decision to switch from cigarettes. Little is known of temporal changes in risk perception of novel tobacco products. Risk perception of heated tobacco increased in Italy and Japan. Difference in risk perception of heated tobacco relative to cigarettes declined.

Abstract
BACKGROUND Little is known about the use of novel heated tobacco products (HTPs) in low- and middle-income countries. We examined among smokers in Mexico the prevalence and correlates of HTP use, as well as reasons for using HTPs. METHODS We analyzed data from five surveys (November 2019-March 2021) of an open cohort of adult smokers (n = 6500), including an oversample of those who also use e-cigarettes. Mixed-effects multinomial logistic models were used to estimate associations between study variables and current HTP use or prior HTP trial relative to never trying HTPs. RESULTS The weighted prevalence of current HTP use was 1.1%. Independent correlates of current HTP use included smoking frequency, intention to quit, e-cigarette use, having partners/family-members who use e-cigarettes, friends who use HTPs, and exposure to HTP information inside/outside tobacco shops. Having partners/family members who smoke and not knowing about the harm of HTPs relative to cigarettes were associated with lower likelihood of current HTP use. Having tried HTPs was more likely among light daily smokers, those with family who use HTPs and exposure to HTP information outside shops and on newspapers/magazines. Among current users, the top reasons for using HTPs were greater social acceptability (50.6%) and lower perceived harm (34.9%) relative to cigarettes. CONCLUSIONS Uptake of HTPs appears relatively low among Mexican smokers, and correlates of use are similar to those for e-cigarette use. Further research is needed to determine if HTPs use promotes or impedes smoking cessation, given current HTP users are also likely to use various nicotine products.

Abstract
Declines in cigarette smoking prevalence in many countries and the consolidation of the tobacco industry have prompted the introduction of other forms of nicotine delivery. These include electronic nicotine delivery systems (ENDS), heated tobacco products (HTPs) and oral nicotine products (ONPs). Evolving over time, some of these products now deliver nicotine at levels comparable to cigarettes and may serve as effective substitutes for smokers. However, certain products, especially ENDS like JUUL, have also appealed to youth and non-smokers, prompting concerns about expanding nicotine use (and potentially nicotine addiction). The tobacco industry could shift away from primarily promoting cigarettes to promoting ENDS, HTPs and/or ONPs, though at this time it continues to heavily promote cigarettes in low and middle-income countries. Differing regulatory regimes may place upward and downward pressures on both cigarettes and these newer products in terms of population use, and may ultimately drive the extent to which cigarettes are or are not displaced by ENDS, HTPs and/or ONPs in the coming decade.

Abstract
INTRODUCTION Electronic cigarettes (e-cigarettes) and heated tobacco products (HTPs) are often considered to be less harmful and safer than combustible cigarettes (CCs). As a result, numerous tobacco product users opt to use e-cigarettes or HTPs as a safer alternative, though the safety of these products is not fully warranted. The present study aimed to assess the various attitudes towards e-cigarettes and/or HTPs among Korean tobacco product users and their associations with the practical use of e-cigarettes and/or HTPs in private or smoke-free public places. METHODS A cross-sectional study using self-administered questionnaires was conducted from March 2019 to July 2019 on 2971 adult tobacco product users. Attitude towards e-cigarettes and/or HTPs, as well as the relative harm perceptions, in association with their practical use in private or smoke-free areas, were also analyzed. RESULTS Among those surveyed, 46.8% were exclusive users (CC-only smokers 23.5%, e-cigarette-only users 10.7%, HTP-only users 12.7%), and 47.6% were poly-users. Compared with non-e-cigarette or non-HTP users, current e-cigarette or HTP users perceived e-cigarettes or HTPs as less harmful than CCs and they were more acceptable to e-cigarettes or HTPs being used indoors. Their positive attitudes were associated with their more frequent use at home or in their car. Less number of participants supported that the government should regulate e-cigarettes or HTPs in the same way as CCs, their attitude being associated with more frequent use in smoke-free public places. CONCLUSIONS E-cigarettes or HTPs users have more positive attitudes toward their tobacco products than non-e-cigarette or non-HTP users. Those with more positive attitudes toward e-cigarettes or HTPs are closely related to their use in smoke-free places.

Abstract
BACKGROUND Heated tobacco products (HTPs) are designed to heat tobacco to a high enough temperature to release aerosol, without burning it or producing smoke. They differ from e-cigarettes because they heat tobacco leaf/sheet rather than a liquid. Companies who make HTPs claim they produce fewer harmful chemicals than conventional cigarettes. Some people report stopping smoking cigarettes entirely by switching to using HTPs, so clinicians need to know whether they are effective for this purpose and relatively safe. Also, to regulate HTPs appropriately, policymakers should understand their impact on health and on cigarette smoking prevalence. OBJECTIVES To evaluate the effectiveness and safety of HTPs for smoking cessation and the impact of HTPs on smoking prevalence. SEARCH METHODS: We searched the Cochrane Tobacco Addiction Group's Specialised Register, CENTRAL, MEDLINE, and six other databases for relevant records to January 2021, together with reference-checking and contact with study authors and relevant groups. SELECTION CRITERIA We included randomised controlled trials (RCTs) in which people who smoked cigarettes were randomised to switch to exclusive HTP use or a control condition. Eligible outcomes were smoking cessation, adverse events, and selected biomarkers. RCTs conducted in clinic or in an ambulatory setting were deemed eligible when assessing safety, including those randomising participants to exclusively use HTPs, smoke cigarettes, or attempt abstinence from all tobacco. Time-series studies were also eligible for inclusion if they examined the population-level impact of heated tobacco on smoking prevalence or cigarette sales as an indirect measure. DATA COLLECTION AND ANALYSIS We followed standard Cochrane methods for screening and data extraction. Our primary outcome measures were abstinence from smoking at the longest follow-up point available, adverse events, serious adverse events, and changes in smoking prevalence or cigarette sales. Other outcomes included biomarkers of harm and exposure to toxicants/carcinogens (e.g. NNAL and carboxyhaemoglobin (COHb)). We used a random-effects Mantel-Haenszel model to calculate risk ratios (RR) with 95% confidence intervals (CIs) for dichotomous outcomes. For continuous outcomes, we calculated mean differences on the log-transformed scale (LMD) with 95% CIs. We pooled data across studies using meta-analysis where possible. MAIN RESULTS We included 13 completed studies, of which 11 were RCTs assessing safety (2666 participants) and two were time-series studies. We judged eight RCTs to be at unclear risk of bias and three at high risk. All RCTs were funded by tobacco companies. Median length of follow-up was 13 weeks. No studies reported smoking cessation outcomes. There was insufficient evidence for a difference in risk of adverse events between smokers randomised to switch to heated tobacco or continue smoking cigarettes, limited by imprecision and risk of bias (RR 1.03, 95% CI 0.92 to 1.15; I2 = 0%; 6 studies, 1713 participants). There was insufficient evidence to determine whether risk of serious adverse events differed between groups due to very serious imprecision and risk of bias (RR 0.79, 95% CI 0.33 to 1.94; I2 = 0%; 4 studies, 1472 participants). There was moderate-certainty evidence for lower NNAL and COHb at follow-up in heated tobacco than cigarette smoking groups, limited by risk of bias (NNAL: LMD -0.81, 95% CI -1.07 to -0.55; I2 = 92%; 10 studies, 1959 participants; COHb: LMD -0.74, 95% CI -0.92 to -0.52; I2 = 96%; 9 studies, 1807 participants). Evidence for additional biomarkers of exposure are reported in the main body of the review. There was insufficient evidence for a difference in risk of adverse events in smokers randomised to switch to heated tobacco or attempt abstinence from all tobacco, limited by risk of bias and imprecision (RR 1.12, 95% CI 0.86 to 1.46; I2 = 0%; 2 studies, 237 participants). Five studies reported that no serious adverse events occurred in either group (533 participants). There was moderate-certainty evidence, limited by risk of bias, that urine concentrations of NNAL at follow-up were higher in the heated tobacco use compared with abstinence group (LMD 0.50, 95% CI 0.34 to 0.66; I2 = 0%; 5 studies, 382 participants). In addition, there was very low-certainty evidence, limited by risk of bias, inconsistency, and imprecision, for higher COHb in the heated tobacco use compared with abstinence group for intention-to-treat analyses (LMD 0.69, 95% CI 0.07 to 1.31; 3 studies, 212 participants), but lower COHb in per-protocol analyses (LMD -0.32, 95% CI -1.04 to 0.39; 2 studies, 170 participants). Evidence concerning additional biomarkers is reported in the main body of the review. Data from two time-series studies showed that the rate of decline in cigarette sales accelerated following the introduction of heated tobacco to market in Japan. This evidence was of very low-certainty as there was risk of bias, including possible confounding, and cigarette sales are an indirect measure of smoking prevalence. AUTHORS' CONCLUSIONS No studies reported on cigarette smoking cessation, so the effectiveness of heated tobacco for this purpose remains uncertain. There was insufficient evidence for differences in risk of adverse or serious adverse events between people randomised to switch to heated tobacco, smoke cigarettes, or attempt tobacco abstinence in the short-term. There was moderate-certainty evidence that heated tobacco users have lower exposure to toxicants/carcinogens than cigarette smokers and very low- to moderate-certainty evidence of higher exposure than those attempting abstinence from all tobacco. Independently funded research on the effectiveness and safety of HTPs is needed. The rate of decline in cigarette sales accelerated after the introduction of heated tobacco to market in Japan but, as data were observational, it is possible other factors caused these changes. Moreover, falls in cigarette sales may not translate to declining smoking prevalence, and changes in Japan may not generalise elsewhere. To clarify the impact of rising heated tobacco use on smoking prevalence, there is a need for time-series studies that examine this association.

Abstract
BACKGROUND AND AIMS In May 2017, black-and-white text nicotine addiction warning labels ('warnings') and health and safety leaflets ('leaflets') became mandatory for nicotine vaping products (NVPs) in England, in accordance with the European Union's Tobacco Products Directive. We compared changes over time in noticing warnings and leaflets, recall of warnings about nicotine and concerns about using NVP due to noticing warnings in England, compared with Canada, the US and Australia, where no warnings and leaflets were mandated. DESIGN 19 005 adult (aged 18+) NVP users, smokers and quitters of cigarettes and NVP from the 2016 and 2018 International Tobacco Control Four Country Smoking and Vaping Surveys in England, Canada, the US and Australia, recruited via probability and non-probability sampling. FINDINGS Noticing warnings increased in England from 4.9% (2016) to 9.4% (2018) (adjusted OR/AOR=1.64, 95% CI=1.15-2.36); this change was larger than changes in Canada (AOR=2.51, 95% CI=1.71-3.69) and the US (AOR=2.22, 95% CI=1.45-3.39). Recall of a nicotine warning increased in England from 86% (2016) to 94.9% (2018) (AOR=5.50, 95% CI=1.57-19.27) but not significantly elsewhere. Noticing leaflets increased in England from 14.6% (2016) to 19.1% (2018) (AOR=1.42, 95% CI=1.15-1.74); this change was larger than in Canada (AOR=1.42, 95% CI=1.12-1.79), the US (AOR=1.55, 95% CI=1.17-2.06) and Australia (AOR=1.51, 95% CI=1.02-2.22). Among those noticing warnings, concern about NVP use did not change significantly between 2016 and 2018 (all countries p>0.081). CONCLUSIONS Introduction of mandatory NVP warnings and leaflets in England was associated with small increases in noticing them but not with changes in concerns about NVP use.

Abstract
OBJECTIVE To evaluate heated tobacco product (HTP) awareness, trial and current use among adult cigarette smokers and vaping product users in four countries with varying regulations governing HTP sales. DESIGN Data came from Wave 2 of the ITC Four Country Smoking and Vaping Survey, collected from February to July 2018. Respondents were current and former smokers and/or users of vaping products (18 years or older) from Canada (CA; n=3778), England (EN; n=4848), the USA (US; n=2846) and Australia (AU; n=1515). At the time of the survey, only Canada and England permitted the sale of contemporary HTPs (eg, IQOS). RESULTS Overall, 30.2% of respondents reported being aware of HTPs (CA=30.4%; EN=31.0%; US=30.2%; AU=27.4%; p=0.346), 2.4% had ever tried HTPs (CA=3.3%; EN=2.4%; US=2.0%; AU=0.9%; p=0.001) and 0.9% currently used HTPs at least monthly (CA=0.8%; EN=1.2%; US=0.7%; AU=0.2%; p<0.001). Trial and current use were higher among those who concurrently smoked and vaped (at least monthly) versus other nicotine use categories (trial: 10.9% v. 1.2%-2.0%, p<0.001; current use: 8.4% v. 0.1%-1.0%, p<0.001). In multivariable analyses, HTP awareness did not differ across countries, whereas odds of trial and current use were lower where HTPs were unavailable. Odds of HTP trial did not differ by regulatory environment when restricting analysis to HTP-aware concurrent smokers-vapers. CONCLUSION Approximately one third of respondents were aware of HTPs, even in the USA and Australia, where contemporary HTPs were not yet on the market. Trial and use were uncommon, except among concurrent smokers-vapers. Restrictions on availability may have limited HTP use generally, but less so for concurrent smokers-vapers.

Abstract
INTRODUCTION Up-to-date monitoring of non-combustible nicotine products (e.g. e-cigarettes, nicotine replacement therapies (NRT), heated tobacco products (HTP); NNP) is important to assess their impact. To date, there is little evidence on the association between ever regular use (defined here as 1 year or more) of NNP and current smoking status. AIMS/METHODS The purpose of this study was to examine the prevalence, and sociodemographic, alcohol and smoking status correlates, of ever regular use of NNP in England in 2020. A cross-sectional survey of adults in England was conducted between February and June 2020. RESULTS A total of 8486 adults were surveyed; 94.9% (8055) were complete cases. The weighted prevalence of ever regular NNP use was 5.4% (n = 436; 95% CI 5.0-6.0), of which 82% (n = 360; 95% CI 78.7-85.8) was single and 18% (n = 79; 95% CI 14.8-22) multiple product use. Amongst ever regular NNP users, the prevalence of ever regular NRT, e-cigarette and HTP use was 64.7% (95% CI 60.1-69), 43.4% (95% CI 38.8-48) and 2.5% (95% CI 1.4-4.5), respectively. In adjusted analysis, ever regular NNP use was associated with smoking status, being significantly higher among current (22.3%; adjusted OR (aOR) 34.9, 95% CI 24.0-50.8) and ex-smokers (12.7%, aOR 19.8, 95% CI 11.1-14.4) than among never-smokers (0.6%). More advantaged occupational grade (aOR, 1.27 95% CI 1.02-1.57) and at least hazardous alcohol use (aOR, 1.38 95% CI 1.06-1.78) were associated with greater prevalence of ever regular NNP use. CONCLUSIONS Ever regularly using NNP was highest among smokers and ex-smokers and rare among never-smokers. Among people who have ever regularly used NNP, NRT is the most popular.

Abstract
INTRODUCTION Heated tobacco products (HTP) have diversified global tobacco markets, and user characteristics remain understudied. This study evaluated sociodemographic characteristics, nicotine-related perceptions and behaviors of current HTP users within a sample of adult (18+ years) nicotine users across four countries. METHODS Data were from current smokers or nicotine vaping product (NVP; known as "e-cigarettes") users from Canada, England, the United States and Australia (n=11,421) who participated in the 2018 ITC Four Country Smoking and Vaping Survey. Current (at-least-monthly) HTP users were characterized (n=441), and weighted multivariable logistic regressions examined correlates of HTP use. RESULTS Compared to non-users, current HTP users were younger (mean age: 44.4 vs 31.0 years; p<0.001) and had higher socioeconomic status (p<0.001). A majority of current HTP users used HTPs non-daily (daily: 40.3% vs non-daily: 59.7%). Most HTP users concurrently used both cigarettes and NVPs (90.5%). Among concurrent cigarette-HTP-NVP users, 36.2% used all three products daily. Use of other combusted tobacco products (cigars, cigarillos, pipe, waterpipe/hookah), cannabis, and binge drinking were each associated with current HTP use. HTP use was more common among smokers intending to quit within 6 months or reporting a quit attempt in the past 18 months, and vapers who had experienced negative side effects. CONCLUSION HTP users in this sample tended to be younger and more affluent. Most reported concurrent use of multiple nicotine products and other substances. Those cigarette smokers who used HTPs appeared more interested in smoking cessation, while some characteristics of concurrent HTP-NVP users were suggestive of dissatisfaction with NVPs. IMPLICATIONS Few studies have scrutinized characteristics of HTP early-adopters in emerging markets. Our results indicate that in 2018, characteristics of established nicotine users who adopted HTP use in four high-income Western countries mirror those of HTP users in East Asian markets (South Korea and Japan) where HTPs are popular. HTP users reported high levels of concurrent use of non-cigarette combusted tobacco products (e.g., cigars, pipe tobacco). These findings point to the need for future longitudinal studies of HTP use given the implications of those use patterns on the harm reduction potential of HTPs. HTP user characteristics may yield important information to consider in regulation of these products.

Abstract
IMPORTANCE Heated tobacco products (HTPs) are promoted as less harmful than combustible cigarettes but epidemiological evidence is scarce, especially in youth. OBJECTIVE To investigate the associations of persistent respiratory symptoms with HTP use, cigarette use, and dual use among Hong Kong youth. DESIGN, SETTING, AND PARTICIPANTS This was a territorywide cross-sectional school-based survey conducted from October 2018 to July 2019 using an anonymous questionnaire. Schools were randomly invited from a proportionate stratified sample in all 18 districts of Hong Kong. Poisson regression models using generalized estimating equations yielded adjusted prevalence ratios (APRs) of respiratory symptoms in (1) former and current HTP (vs never) users in the whole sample and stratified by cigarette use status and (2) exclusive HTP and dual users vs exclusive cigarette users. Statistical analysis was performed from October 2020 to March 2021. EXPOSURES Former and current use of cigarettes, HTPs, e-cigarettes, and other tobacco products. MAIN OUTCOMES AND MEASURES Respiratory symptoms for 3 consecutive months in the past 12 months. RESULTS The study included 33 627 students with a mean (SD) age of 14.8 (1.9) years; 51.3% (18 171) were boys. Respiratory symptoms were reported by 16.3% (n = 5549) of all students, 29.3% (n = 226) of current users of e-cigarettes, 31.2% (n = 314) of current users of cigarettes, and 33.5% (n = 179) of current users of HTPs. Respiratory symptoms were associated with former (APR, 1.30; 95% CI, 1.06-1.59) and current (APR, 1.59; 95% CI, 1.23-2.06) vs never HTP use and current vs never cigarette use (APR, 1.50; 95% CI, 1.30-1.74) after adjusting for various tobacco use. Associations between respiratory symptoms and current vs never HTP use were observed in never (APR, 1.88; 95% CI, 1.36-2.59) and former (APR, 2.15; 95% CI, 1.12-4.12) cigarette users, but not in current cigarette users (APR, 1.24; 95% CI, 0.97-1.59). Respiratory symptoms were associated with exclusive ever HTP use (APR, 1.46, 95% CI, 1.15-1.86) and ever dual use (APR, 1.29; 95% CI, 1.08-1.54) vs exclusive ever cigarette use. There was no association between exclusive current HTP (vs cigarette) use and respiratory symptoms (1.40; 95% CI, 0.93-2.11). CONCLUSIONS AND RELEVANCE This cross-sectional study found that former and current HTP use were associated with persistent respiratory symptoms among youth, especially among never and former cigarette users. Respiratory symptoms were more prevalent in ever exclusive HTP users and ever dual users than ever exclusive cigarette users. These findings suggest that using HTPs instead of cigarettes may not reduce health risks.

Effects of tobacco product type and characteristics on appeal and perceived harm: Results from a discrete choice experiment among Guatemalan adolescents. Prev Med 2021; 148:106590.

Abstract
Guatemala is one of the few countries where both heated tobacco products (HTPs) and electronic cigarettes (e-cigarettes) remain unregulated. We used a discrete choice experiment (DCE) administered to 2038 high school students to assess how tobacco product attributes influence their appeal among Guatemalan adolescents. Participants were randomly assigned to evaluate 4 of 32 contrasting sets, each containing 3 packs (1 of each product type). Experimental manipulations included: product type, brand, nicotine content and flavor. Participants then indicated which product they were most and least interested in trying and would be most and least harmful to their health. Conditional logistic regression models were used to assess the impact of product characteristics on choice. Product type accounted for almost 90% of variation in choices. Respondents were less interested in trying HTPs (B = -0.93; p < 0.001) and viewed them as more harmful (B = 2.77; p < 0.001) compared to cigarettes. They were more interested in trying e-cigarettes (B = 1.22; p < 0.001), which were also perceived as less harmful (B = -1.47; p < 0.001) compared to cigarettes. Products without nicotine were of more interest for trying (B = 0.14; p < 0.001) and perceived as more harmful (B = 0.20; p < 0.001) than those with. Students were more interested in trying a flavor compared to regular tobacco and among the flavors, berry was the highest rated one (B = 0.28; p < 0.001). Finally, in this country with weak tobacco control, e-cigarettes appear to be more appealing and perceived as less harmful than HTPs and cigarettes. Packaging and flavoring regulations are urgently needed on these products as they are a marketing strategy targeting adolescents.

Abstract
BACKGROUND Harm perceptions of tobacco and nicotine products can influence their use and could be targeted by policies to change behaviour. IQOS was introduced to the UK in 2016, and there is little independent qualitative research on IQOS harm perceptions. This study explored the perceived health harms of IQOS to users and those exposed to the emissions, what shapes these perceptions, and what participants wanted to know about the harms of IQOS. METHODS Qualitative interviews in London, UK, with 30 adult current and former IQOS users who currently smoked or quit smoking in the last 2 years. RESULTS IQOS was perceived as less harmful than smoking but not risk-free, although there was great uncertainty. Influences on harm perceptions were consolidated into six themes: (1) dominance of manufacturer claims influenced perceptions that IQOS is less harmful than smoking to users and those around them, although mistrust of the tobacco industry heightened scepticism about harms; (2) limited independent and long-term research led to uncertainty about harms, although some participants trusted IQOS would not be marketed if it were very harmful. Participants wanted more independent and long-term studies into harm; (3) appearance of HEETS (tobacco sticks) packaging conveyed reduced harm because packets were 'pretty', without graphic/specific warnings, although written warnings conveyed some harm. Participants wanted more information on HEETS packets about harms; (4) process of heating and HEETS contents-heating, compared with burning, tobacco was perceived to produce fewer harmful chemicals, while tobacco, nicotine, and chemicals in HEETS were perceived to cause some harm. Participants wanted clarification about the harms of heating tobacco and HEETS ingredients; (5) improvements in physical health and personal appearance reduced perceptions of harm; (6) differences in sensory experiences (taste, sight, smell) when using IQOS over smoking reduced perceptions of harm, while 'black' deposits inside IQOS led to perceptions of some harm. Reduced volume and smell of IQOS emissions also reduced perceptions of harm to non-users exposed to the emissions. CONCLUSIONS IQOS was perceived as less harmful than smoking but not risk-free, although there was great uncertainty. Participants wanted clarification about IQOS harms from independent sources in accessible forms, specifically related to HEETS ingredients, heating tobacco, and emissions to others.

Abstract
Given that many patients with chronic obstructive pulmonary disease (COPD) smoke despite their symptoms, it is important to understand the long-term health impact of cigarette substitution with heated tobacco products (HTPs). We monitored health parameters for 3 years in COPD patients who substantially attenuated or ceased cigarette consumption after switching to HTPs. Changes in daily cigarette smoking, annualized disease exacerbations, lung function indices, patient-reported outcomes (CAT scores) and 6-minute walk distance (6MWD) from baseline were measured in COPD patients using HTPs at 12, 24 and 36 months. These were compared to a group of age- and sex-matched COPD patients who continued smoking. Complete data sets were available for 38 patients (19 in each group). Subjects using HTPs had a substantial decrease in annualized COPD exacerbations within the group mean (± SD) from 2.1 (± 0.9) at baseline to 1.4 (± 0.8), 1.2 (± 0.8) and 1.3 (± 0.8) at 12-, 24- and 36-month follow-up (p < 0.05 for all visits). In addition, substantial and clinically significant improvements in CAT scores and 6MWD were identified at all three time points in the HTP cohort. No significant changes were observed in COPD patients who continued smoking. This study is the first to describe the long-term health effects of HTP use in COPD patients. Consistent improvements in respiratory symptoms, exercise tolerance, quality of life, and rate of disease exacerbations were observed in patients with COPD who abstained from smoking or substantially reduced their cigarette consumption by switching to HTP use.

The Frequency of Use and Harm Perception of Heated Tobacco Products (HTPs): The 2019 Cross-Sectional Survey among Medical Students from Poland. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph18073381. [PMID: 33805180 PMCID: PMC8037208 DOI: 10.3390/ijerph18073381] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 02/08/2021] [Revised: 03/20/2021] [Accepted: 03/22/2021] [Indexed: 11/18/2022]
Abstract
Heated tobacco products (HTPs) are devices for generating a nicotine aerosol by heating the tobacco sticks. This study aimed to assess (1) the prevalence of HTP and tobacco cigarette usage among medical students, (2) to characterize smoking habits and (3) to assess students’ awareness and opinions about HTPs. A cross-sectional survey on the frequency and attitudes toward cigarettes, e-cigarettes and HTP use was performed between 2019–2020 at the Medical University of Silesia in Katowice (Poland). The data were obtained from 1344 students aged 21.8 ± 1.9 years (response rate: 66.9%). Current traditional tobacco use was 13.2%, e-cigarettes use 3.5%, and HTP use 2.8% of students. Duration of use was shorter among HTPs users comparing to cigarette smokers (p < 0.001) although the number of tobacco sticks used daily was similar (p = 0.1). Almost 30% of respondents have ever tried HTPs. HTPs were considered safe by 5.3% of respondents (43.2% of HTP users vs. 3.9% of non-HTP users, p < 0.001). HTP users were more likely to report that heating tobacco is not addictive (odds ratio (OR) = 8.9, 95% confidence interval (CI): 1.8–45.8) and disagreed with a public ban on HTP use (OR = 4.9, 95%CI: 2.5–9.8). Among students, HTP use was less popular than cigarette smoking, but awareness of their presence is widespread.

Abstract
Background Heated tobacco products (HTP) are new forms of tobacco consumption with limited information available on their use among the general population. Our objective is to analyse the prevalence and associations of use of HTP across 11 countries in Europe.Methods Within the TackSHS Project, in 2017-2018 we conducted a cross-sectional study with information on HTP use in the following countries: Bulgaria, England, France, Germany, Greece, Italy, Latvia, Poland, Portugal, Romania and Spain. In each country, face-to-face interviews were performed on a representative sample of around 1,000 subjects aged ≥15 years, for a total of 10,839 subjects.Results Overall, 27.8% of study participants were aware of HTPs, 1.8% were ever HTP users (ranging from 0.6% in Spain to 8.3% in Greece), and 0.1% were current users. Men were more frequently HTP ever users than women (adjusted odds ratio, aOR=1.47; 95% confidence interval, CI: 1.11-1.95). Ever HTP use was inversely related to age (p for trend<0.001) and more frequent in ex-smokers (compared with never smokers, aOR=4.32, 95% CI: 2.69-6.95) and current smokers (aOR=8.35, 95% CI: 5.67-12.28), and in electronic cigarette past users (compared with never users, aOR=5.48, 95% CI: 3.46-8.68) and current users (aOR=5.92, 95% CI: 3.73-9.40).Conclusions In 2017-2018, HTP use was still limited in Europe among the general population, however the dual use of these products, their high use among younger generations and the interest of non-smokers in these products are worrying and indicate the need for close monitoring in terms of prevalence and the characteristics of users.

Abstract
Since the advent of heated tobacco products in June 2017 in South Korea, the sale of heated tobacco products accounted for 10.5% of total tobacco sales in 2019. However, the decreasing trend in total tobacco sales is gradually weakening and the number of visitors using stop smoking services has also dropped. This study examines the association between the use of new tobacco products and related products and cessation behaviors. A cross-sectional study using a self-administered questionnaire was conducted from March 2019 to July 2019 for 2831 adult tobacco users. The difference in rates of quit attempts using the type of tobacco products and related products in the past year were noted (55.6% (any cigarette smoker), 46.7% (any e-cigarette user), and 39.6% (any heated tobacco product user)). About a 30% increase in quit attempts was observed for the triple users of either conventional cigarette or heated tobacco product than exclusive users. Exclusive heated tobacco product and e-cigarette users were approximately 40% and 20% less likely to quit the product they used than exclusive cigarette smokers, respectively. These findings can explain recent occurrences in South Korea, such as the reduction of visitors at smoking cessation clinics and the attenuation of the decline in tobacco sales.

Abstract
The heated tobacco product (HTP) IQOS was authorized for sale in the US in 2019. We investigated how young adults with experience using multiple tobacco products reacted to, perceived, and developed interest in IQOS, informing policies that might prevent HTPs from becoming ubiquitous. We used a novel qualitative method in which 33 young adult tobacco users in California (fall 2019) "unboxed" an IQOS device, tobacco sticks, and marketing materials and narrated their impressions and opinions. We conducted content and thematic analyses of participants' reactions, sensory experiences, and interest. Multiple attributes influenced appeal for participants, including sleek electronic design, novel technology, perceived harmfulness, complexity, and high cost. The "no smoke" claim and heating technology suggested that smoking IQOS was safer than smoking cigarettes. Public health programs should closely monitor HTP marketing and uptake, particularly as "reduced exposure" claims were authorized in July 2020. Evidence-based regulations (e.g., requiring plain packaging for tobacco sticks), actions addressing IQOS' unique attributes (e.g., regulating device packaging to reduce high-tech appeal), and public education might help to counter the appeal generated by potentially misleading IQOS marketing tactics.

Reasons for Regularly Using Heated Tobacco Products among Adult Current and Former Smokers in Japan: Finding from 2018 ITC Japan Survey.

Abstract
The market growth of heated tobacco products (HTPs), such as IQOS, Ploom TECH, and glo, has increased dramatically in Japan since 2016. Little is known about the reasons why current and former smokers are using HTPs. The data for this cross-sectional study were from the 2018 (Wave 1) International Tobacco Control (ITC) Japan Survey, a national web-based survey of 4500 people, including 658 current HTP users, of whom 549 were concurrently smoking cigarettes and 109 were former smokers. The most common reasons for regularly using HTPs were: beliefs that HTP are less harmful than cigarettes to themselves (90.6%) or to others (86.7%), enjoyment (76.5%), and social acceptability (74.4%). About half of current smokers (55.1%) reported using HTPs because these products might help them quit smoking. However, a near-equal percentage (52.0%) of current smokers reported using HTPs to replace some of the cigarettes they smoked so that they did not have to give up smoking altogether. If smokers are using HTPs to complement rather than quit their smoking, then the harm reduction potential of HTPs suggested by the toxicity studies will be diminished.

Lee CM. The Impact of Heated Tobacco Products on Smoking Cessation, Tobacco Use, and Tobacco Sales in South Korea. Korean J Fam Med 2020; 41:273-281. [PMID: 32961046 PMCID: PMC7509116 DOI: 10.4082/kjfm.20.0140] [Citation(s) in RCA: 20] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2020] [Accepted: 07/07/2020] [Indexed: 11/25/2022] Open
Abstract
Heated tobacco products (HTPs), a hybrid between conventional and electronic cigarettes, were first launched in South Korea in June 2017. Owing to advertisements stating that HTPs are odorless, tar-free, and less harmful to health, the sales of HTPs have grown quickly enough to account for about 10% of the total tobacco market in a year. HTP use by young, highly educated, and high-income groups had a significant impact on both the overall tobacco market over the past 3 years and the smoking and quitting behaviors of smokers. Based on national smoking rate statistics, tobacco sales trends, and the number of visitors to smoking cessation clinics, the following changes have been identified: (1) The decline in current smoking rates has slowed or rose in some groups. (2) The decline in total cigarette sales has slowed but rose again in the first quarter of 2020. (3) The number of visitors to smoking cessation clinics decreased just after the advent of HTPs. These results may be due to the insufficient support of tobacco regulation policies but also coincide chronologically with the appearance of HTPs in South Korea. It is necessary to investigate the usage rate of various tobacco products, including HTPs and e-cigarettes, to examine the health risks of novel tobacco products and provide accurate information to users and policymakers. Finally, tobacco companies are continuously developing new product concepts to escape the regulation of existing cigarettes; thus, comprehensive management measures for all nicotine-containing products are needed.

Abstract
IntroductionHeated tobacco products (HTPs) are increasingly popular worldwide, but whether they aid or undermine cigarette abstinence remains uncertain. We examined the predictors of HTP initiation and the prospective association of HTP use with cigarette abstinence in community-based smokers in Hong Kong.DesignSecondary analysis of a randomised clinical trial aimed to evaluate the effectiveness of brief advice and referral for smoking cessation. The interventions were not related to HTP use.Participants and settings1213 carbon monoxide-verified daily cigarette smokers with intentions to quit or reduce smoking proactively recruited from community sites throughout Hong KongMain exposureCurrent (past 7 day) use of HTP at baseline.Main outcomeSelf-reported 7-day point-prevalence cigarette abstinence at 6 months (exclusive use of HTP permitted).ResultsAt baseline, 201 (16.6%) and 60 (4.9%) were ever and current HTP users, respectively. During the 6-month follow-up period, 110 of 1012 (10.9%) never users at baseline initiated HTPs. Younger age and higher education significantly predicted initiation. After adjusting for sociodemographic, smoking-related and quitting-related factors, current HTP use at baseline was not associated with cigarette abstinence at 6 months (adjusted prevalence ratio (aPR) 1.08, 95% CI 0.63 to 1.85). The results were similar in persistent users from baseline to 1-month/3-month follow-up (vs non-users; aPR 1.14, 95% CI 0.57 to 2.29). Use of smoking cessation service between baseline and 3-month follow-up significantly predicted cigarette abstinence (aPR 1.70, 95% CI 1.26 to 2.30).ConclusionHTP use was not associated with cigarette abstinence at 6 months in a community-based cohort of smokers with intentions to quit or reduce smoking.Trial registration detailsClinicalTrials.gov, NCT03565796.

Kim SH, Kang SY, Cho HJ. Beliefs about the Harmfulness of Heated Tobacco Products Compared with Combustible Cigarettes and Their Effectiveness for Smoking Cessation among Korean Adults. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:E5591.

Abstract
Heated tobacco products (HTPs) have been widely used in Korea since their introduction in 2017. In this study, we investigated the perceptions of their relative harmfulness and smoking cessation effects. We performed an online survey in 7000 Koreans in 2018 (2300 males and 4700 females aged 20-69 years) by matching their age, sex, and provincial distribution. To investigate the factors causing HTPs to be perceived as less harmful than combustible cigarettes (CCs) and helpful for smoking cessation, we used multivariable logistic regression analyses. HTPs were less harmful than CCs in 16.8% of participants, particularly among HTP-only users and dual and triple users of HTPs, electronic cigarettes (ECs), or CCs than among CC-only users, those who were aged ≤ 34 years, males, and those with higher incomes. HTPs were reportedly helpful for smoking cessation in 11.2% of participants. Similar perceptions were more likely among HTP-only users, as well as dual and triple users than among CC-only users and adults with higher education/incomes. Although Korean adults generally had negative perceptions of the harmfulness and smoking cessation effects of HTPs compared with CCs, dual and triple users were more likely to have positive perceptions. Monitoring the use of multiple tobacco products and HTPs is a new challenge for Korean policymakers.

Abstract
This study aimed to evaluate the opinions of family physicians, who have an important place in preventive health services, on some tobacco products. The sample of the descriptive study was composed of family physicians working in 408 family health centers serving Samsun, Turkey. The data were obtained by distributing a questionnaire prepared by the researchers to volunteer family physicians during in-service trainings organized by the Samsun Provincial Directorate of Health in February and March 2019. In all, 322 (79%) family physicians who participated in the trainings were included in the study. The average age of the participating physicians was 45.0 ± 7.6 years; 61.5% of them were male. More than one third (36.0%) of family physicians said that they had never smoked, while 23.6% of them were current smokers. Most (85.0%) said that they knew what an electronic cigarette was, 94.7% of them were familiar with hookahs, and 9.0% knew about I Quit Ordinary Smoking (IQOS). It is important to inform all healthcare professionals, and especially family physicians, about those products marketed by the tobacco industry as "less harmful" than cigarettes. It is thought that providing appropriate counseling services to these professionals will contribute to the fight against tobacco use.

Abstract
In Japan, the tobacco industry promotes heated tobacco products (HTPs) as a reduced-risk tobacco product. This study examines: (1) smokers' harm perceptions of HTPs relative to combustible cigarettes; (2) differences in relative harm perceptions between exclusive smokers and smokers who use HTPs (concurrent users) and between concurrent users based on frequency of product use; and (3) if smokers who were exposed to HTP advertising hold beliefs that are consistent with marketing messages of lower harmfulness. This cross-sectional study included 2614 adult exclusive cigarette smokers and 986 concurrent users who reported their perceptions of harmfulness of HTPs compared to cigarettes, as well as their exposure to HTP advertising in the last six months. Among all smokers, 47.5% perceive that HTPs are less harmful than cigarettes, 24.6% perceive HTPs to be equally as harmful, 1.8% perceive HTPs as more harmful, and 26.1% did not know. Concurrent users are more likely than exclusive smokers to believe that HTPs are less harmful (62.1% versus 43.8%, p < 0.0001) and less likely to report that they did not know (14.3% versus 29.4%, p < 0.0001). Frequent HTP users are more likely than infrequent users to believe that HTPs are less harmful (71.7% versus 57.1%, p ≤ 0.001). Believing that HTPs are less harmful than cigarettes was associated with noticing HTP advertising on TV (p = 0.0005), in newspapers/magazines (p = 0.0001), on posters/billboards (p < 0.0001), in stores where tobacco (p < 0.0001) or where HTPs (p < 0.0001) are sold, on social media (p < 0.0001), or in bars/pubs (p = 0.04). HTP users were significantly more likely than non-HTP users to believe that HTPs are less harmful than cigarettes, with this belief being more prominent among frequent users. Smokers who have been exposed to HTP advertising were more likely to perceive HTPs as less harmful than cigarettes.

Adult Smokers' Awareness and Interest in Trying Heated Tobacco Products: Perspectives from Mexico, where HTPs and E-Cigarettes Are Banned. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:E2173. [PMID: 32218161 PMCID: PMC7177513 DOI: 10.3390/ijerph17072173] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/09/2020] [Revised: 03/17/2020] [Accepted: 03/19/2020] [Indexed: 12/19/2022]
Abstract
BACKGROUND We evaluated smokers' perceptions of heated tobacco products (HTPs) in Mexico, where industry publically lobbied to introduce HTPs into this country that banned both HTPs and e-cigarettes. METHODS Online surveys (November 2018 to July 2019) were analyzed from adults who only smoked cigarettes (n = 2091) or who smoked and used e-cigarettes ("dual users"n = 1128). Logistic models regressed HTP awareness, interest to trying HTPs, and having seen HTPs for sale (only among aware participants) on sociodemographics and tobacco-related variables. RESULTS Of the 17.1% who were aware of HTPs, 52.7% reported having seen HTPs for sale. Of all respondents, 75% were somewhat or very interested in trying HTPs. Compared to their counterparts, more frequent smokers, dual users, those exposed to online e-cigarette ads, and those with friends who used e-cigarettes were both more aware of and interested in trying HTPs. Greater awareness was also associated with higher education, recent attempts to quit, receipt of email e-cigarette ads, and smoking among friends and family. Seeing HTPs for sale was higher for those who recently attempted to quit, were exposed to e-cigarette ads online or by email, or had friends who used e-cigarettes. CONCLUSION Interest in HTPs is high among smokers in Mexico, which already has a large black market for illegal e-cigarettes. HTPs use should be monitored in this context, especially given the public health impacts of HTPs are unclear.
