Abstract
BACKGROUND While heated tobacco products (HTPs) may affect pulmonary function, the evidence supporting the utility of screening for HTP use in clinical settings is insufficient. We examined the association between HTP use and airway obstruction after switching from cigarettes. METHOD The study subjects were patients aged ≥20 years undergoing surgery from December 2021 to September 2022 who completed spirometry and reported tobacco (cigarette and HTP) use status during the preoperative assessment. Airway obstruction was defined as forced expiratory volume in 1 s to forced vital capacity ratio below the lower limit of normal. Current tobacco use was defined as past-30-day use. Multivariable Poisson regression analysis was performed to examine the associations between HTP use and airway obstruction by adjusting for demographic characteristics, lifetime cigarette smoking (pack-year) and duration of smoking cessation. RESULTS Overall (N=2850, 55.4% women, mean age 62.4), 4.6% and 10.7% reported current HTP use and cigarette smoking, respectively. 16.8% had airway obstruction. Airway obstruction was more common among current HTP-only users (adjusted prevalence ratio (APR)=2.32), current cigarette-only smokers (APR=2.57) and current dual users (APR=2.82) than never-tobacco users. Among current tobacco users (N=398), the prevalence of airway obstruction was not significantly different between HTP-only users and cigarette-only smokers. Among former cigarette smokers (>30-day cigarette quitters) (N=1077), current HTP users had 1.42 times the increased prevalence of airway obstruction than never-HTP users after adjusting for cigarette pack-year; a stronger association was observed when the analysis was restricted to ≥5-year cigarette quitters (N=772) (APR=1.96, vs never HTP users). CONCLUSION Current HTP use was associated with airway obstruction among patients with cancer who had completely switched from cigarettes even after quitting smoking for a long period. Patients should be routinely screened for HTP use and advised to quit any tobacco.

Abstract
Heated Tobacco Products (HTPs) purport to reduce exposure to tobacco-related toxicants compared to combustible cigarettes. This cross-sectional study examined the content of nicotine, two humectants (propylene glycol (PG) and vegetable glycerin (VG)), and four tobacco-specific nitrosamines (TSNAs: NNN, NNK, NAT, and NAB) in the tobacco filler of a popular HTP brand (IQOS). Non-menthol and menthol IQOS sticks were purchased from nine countries between 2017 and 2020 and were classified into two versions ("Bold" and "Light") using Philip Morris's flavor descriptors. The average nicotine concentration was 4.7 ± 0.5 mg/stick, and the highest nicotine concentration was found in products from Japan (5.1 ± 0.2 mg/stick). VG was the dominant humectant found in all sticks, with an average concentration of (31.5 ± 2.3 mg/stick). NNN, NNK, and NAT were substantially higher in the "Bold" sticks than the "Light" sticks. Significant differences between countries for TSNAs were also observed: the NAT and NAB contents were the highest in the "Light" products from Canada (192.5 ± 24.1 and 22.9 ± 1.0 ng/stick, respectively); the NNK concentration was the highest in the "Bold" products from Poland (64.8 ± 7.9 ng/stick); and the highest NNN concentrations were observed in the "Bold" products from South Africa (488.9 ± 26.7 ng/stick). As NNN and NNK are known human carcinogens, and as humectants like PG and VG can degrade into toxic carbonyl compounds upon heating, monitoring the concentration of these chemicals in HTPs is important for protecting users' health and ensuring compliance with regulations.

Abstract
INTRODUCTION Heated tobacco products (HTPs) and e-cigarettes (ECs) have gained traction as alternatives for harm reduction, especially in Japan. In particular, the use of HTPs is rapidly gaining popularity among young adults in Japan, with a prevalence of 10.9% in 2020. Despite uncertainties regarding the health effects of HTPs and ECs, concerns regarding nicotine and carcinogens persist. Although physicians play a vital role in smoking cessation, they lack awareness and concerns regarding HTPs. This study aimed to assess the prevalence, knowledge, and concerns regarding HTPs and ECs among young Japanese physicians. METHODS A cross-sectional online survey was conducted in 2021 with 529 young Japanese physicians aged 24-39 years. Parameters assessed included awareness, smoking status, knowledge of HTPs and ECs, and concerns related to HTPs. Statistical analyses were conducted to assess prevalence, knowledge, and concerns by smoking status using the chi-squared test and logistic regression. RESULTS Most participants were aware of HTPs (89.0%) and ECs (71.3%). Young male physicians preferred HTPs, while females favored ECs. Primary sources of information included newspapers and stories (56.8%), and TV (37.4%). Non-smokers (89.0%) demonstrated limited knowledge of these products. Concerns were highest and lowest among non-smokers and HTP users, respectively, with safety concerns being the most prevalent. CONCLUSIONS Young physicians exhibited lower smoking rates than the general population, but HTP use was prominent among young male physicians. Concerns varied based on smoking status, indicating the need to address these issues among healthcare professionals. Despite high awareness, knowledge gaps, particularly among non-smokers, highlight the importance of public health and educational campaigns to disseminate knowledge among physicians, regardless of medical specialty.

Abstract
BACKGROUND Heated tobacco product (HTP) use continues in Japan as the second most common product after cigarettes. While the health effects of HTPs and their secondhand emissions are not well-studied, the tobacco industry has actively marketed HTPs as a smokeless, health-conscious alternative to cigarettes to encourage home consumption. We investigated the prevalence of current tobacco product use and usage at home. METHODS The present study conducted a cross-sectional analysis of data from the 2023 wave of a nationwide, Internet-based, self-reported survey. 29,354 individuals aged 16-74 were included in the analysis. We assessed the prevalence of current (past-30-day) use for HTPs, cigarettes, non-cigarette combustible tobacco, and dual (combustible plus HTP) use. The frequency of use (daily or more than monthly) in the home was calculated for both HTPs and combustible tobacco. Multivariable Poisson regression models were employed to identify factors associated with home usage. Adjusted prevalence ratios (APRs) and 95% confidence intervals (CIs) were computed. All analyses were weighted to address the Internet-based sample's selectivity and yield nationally representative estimates. RESULTS In 2023, the prevalence of current use was 12.4% (HTPs), 18.9% (cigarettes), 3.6% (non-cigarette combustible tobacco), and 7.4% (dual use). Among current users of any tobacco (N = 5,818), 49.8% reported daily tobacco usage within their homes, and 67.1% reported monthly or more frequent home usage. Compared to exclusive combustible tobacco smokers, exclusive HTP users exhibited higher prevalence of daily home usage (APR = 1.54; 95% CI = 1.43-1.67), as did dual users (APR = 1.10; 95% CI = 1.01-1.20). Daily home usage prevalence was notably higher for those without complete tobacco-free rules at home or workplaces, older individuals, and those with lower education levels. Those living with adult or child household member and current drinkers showed significantly lower daily home usage prevalence. CONCLUSION Home usage was more common among HTP users than among combustible tobacco smokers. Ongoing efforts to assess and address the impact of indoor tobacco product use, including HTPs, on health are warranted. Regulatory and educational strategies should be considered to discourage tobacco consumption in both public and private spaces.

Abstract
BACKGROUND Heated tobacco products (HTPs) have gained global popularity, but their health risks remain unclear. Therefore, the current study aimed to identify plasma metabolites associated with smoking and HTP use in a large Japanese population to improve health risk assessment. METHODS Metabolomics data from 9,922 baseline participants of the Tsuruoka Metabolomics Cohort Study (TMCS) were analyzed to determine the association between smoking habits and plasma metabolites. Moreover, alterations in smoking-related metabolites among HTP users were examined based on data obtained from 3,334 participants involved from April 2018 to June 2019 in a follow-up survey. RESULTS Our study revealed that cigarette smokers had metabolomics profiles distinct from never smokers, with 22 polar metabolites identified as candidate biomarkers for smoking. These biomarker profiles of HTP users were closer to those of cigarette smokers than those of never smokers. The concentration of glutamate was higher in cigarette smokers, and biomarkers involved in glutamate metabolism were also associated with cigarette smoking and HTP use. Network pathway analysis showed that smoking was associated with the glutamate pathway, which could lead to endothelial dysfunction and atherosclerosis of the vessels. CONCLUSIONS Our study showed that the glutamate pathway is affected by habitual smoking. These changes in the glutamate pathway may partly explain the mechanism by which cigarette smoking causes cardiovascular disease. HTP use was also associated with glutamate metabolism, indicating that HTP use may contribute to the development of cardiovascular disease through mechanisms similar to those in cigarette use.

Abstract
BACKGROUND Smoking cessation is the most important intervention in chronic obstructive pulmonary disease (COPD), asthma, and asthma-COPD overlap (ACO); however, high rates of current cigarette smoking are observed in adults with these respiratory diseases. Meanwhile, rapidly increasing use of heated tobacco products (HTPs) is observed in Japan; however, the status of HTPs use has not been fully understood in adults with COPD, asthma, and ACO. This study aimed to reveal the association between COPD, asthma, and ACO and HTPs use in adults. METHODS Data on Japanese individuals ≥ 40 years old obtained from the Japan Society and New Tobacco Internet Survey were analyzed. The prevalence of HTPs use in adults with COPD, asthma, and ACO, among individuals categorized into three groups according to cigarette smoking (never, former, and current), was calculated and the relationship between each disease and HTPs use were evaluated. The clinical diagnosis of these diseases was based on the self-reported diagnosis, as obtained from questionnaires. RESULTS A total of 19,308 individuals were included. The proportions of never, past, and current cigarettes smokers were 10,900 (56.5%), 4,903 (25.4%), and 3,505 (18.2%), respectively, and that of HTPs use was 1,813 (9.4%). In current cigarettes smokers, the adjusted odds ratios (ORs) of HTPs use was 2.88 (95% CI [confidence interval], 1.86-4.47), 1.23 (95% CI, 0.99-1.52), and 5.81 (95% CI, 3.12-10.82) in adults with COPD, asthma, and ACO compared to those without these respiratory diseases, respectively. Meanwhile, in past cigarettes smokers, the adjusted ORs of HTPs use was 0.51 (95% CI, 0.24-1.08), 0.69 (95% CI, 0.53-0.88), and 0.25 (95% CI, 0.06-1.07) in adults with COPD, asthma, and ACO, respectively. CONCLUSIONS HTPs use is more prevalent among current cigarettes smokers with COPD, asthma, and ACO compared to those without these respiratory diseases. Complete cessation of smoking both cigarettes and HTPs is the only way to achieve complete smoking cessation, therefore, adults with COPD, asthma, and ACO need to make greater efforts to quit smoking.

Abstract
AIMS Smoking causes DNA methylation (DNAm) alterations that lead to lung cancer development. Although the use of heated tobacco products (HTPs) has recently increased, their impact on health remains unclear. This study aimed to evaluate the effects of HTPs on DNAm and gene transcription in human lung epithelial cells in vitro. MAIN METHODS Human lung adenocarcinoma (A549) cells with type II alveolar epithelial characteristics were treated with aerosol extracts of two HTPs or a smoke extract of combustible reference cigarette (RC). Global 5-methylcytosine (5-mC) and 5-hydroxymethylcytosine (5-hmC) levels were quantified using dot blot analysis. Furthermore, reduced representation of bisulfite sequencing, DNA microarray, and quantitative PCR analyses were performed to determine CpG methylation and gene transcription changes induced by HTP and RC. KEY FINDINGS Global 5-mC and 5-hmC levels were decreased by the RC extract but not the HTP extracts. However, an HTP extract altered the CpG methylation pattern, and Gene Ontology enrichment analysis of the differentially methylated regions of the RC and HTP groups showed a similar pattern. The HTP extract affected gene expression, albeit to a lesser extent than the RC extract. In particular, the HTP extract markedly affected the mRNA expression and promoter methylation of cytochrome P450 family 1 subfamily A member 1 (CYP1A1), which is associated with carcinogenic risk. SIGNIFICANCE The study results suggest that HTPs as well as conventional combustible cigarettes can alter CpG methylation and gene transcription in lung epithelial cells.

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
OBJECTIVES To investigate the association between secondhand-aerosol exposure from heated tobacco products (HTPs) and respiratory symptoms among current non-smokers. DESIGN Cross-sectional study. SETTING Internet survey conducted between 8 and 26 February 2021 in Japan. PARTICIPANTS Non-smoking respondents at the survey aged 15-80 years. EXPOSURE Self-reported secondhand-aerosol exposure. PRIMARY AND SECONDARY OUTCOMES We defined asthma/asthma-like symptoms as a primary outcome and persistent cough as a secondary outcome. We examined the association between secondhand-aerosol exposure from HTPs and respiratory symptoms (asthma attacks/asthma-like symptoms and persistent cough). The prevalence ratio (PR) and 95% CI were calculated by using weighted, multivariable 'modified' Poisson regression models. RESULTS Of the 18 839 current non-smokers, 9.8% (95% CI 8.2% to 11.7%) and 16.7% (95% CI 14.8% to 18.9%) of those who were exposed to secondhand aerosols reported asthma attacks/asthma-like symptoms and persistent cough, whereas 4.5% (95% CI 3.9% to 5.2%) and 9.6% (95% CI 8.4% to 11.0%) of those who were not, respectively. Secondhand-aerosol exposure was associated with respiratory symptoms (asthma attacks/asthma-like symptoms: PR 1.49, 95% CI 1.21 to 1.85; persistent cough: PR 1.44, 95% CI 1.21 to 1.72) after adjusting for covariates. CONCLUSION Secondhand-aerosol exposure from HTPs was associated with both asthma attacks/asthma-like symptoms and persistent cough. These results provide policymakers with meaningful information in the regulation of HTP use for the protection of current non-smokers.

Abstract
AIMS We aimed to assess the cross-sectional association of heated tobacco product (HTP) use with prediabetes and diabetes. METHODS The present analysis included 8950 workers from 5 companies (Study I) and 31,341 workers from another large company (Study II), who participated in the Japan Epidemiology Collaboration on Occupational Health Study. The participants were divided into five groups: never smokers, past smokers, exclusive HTP users, dual users of cigarettes and HTPs, and exclusive cigarette smokers. Diabetes and prediabetes were defined according to the fasting blood glucose and HbA1c levels and self-reported diabetes treatment, using the American Diabetes Association criteria. We analyzed the data of Study I and II separately, and then pooled these estimates using the fixed-effect models, with adjustment for a wide range of covariates. RESULTS In this study that included 40,291 participants (mean age, 46.6 years; men, 84.3%), about half of the current tobacco-related product users reported using HTPs. Exclusive HTP users had higher odds of prediabetes (pooled odds ratio 1.36; 95% CI 1.25-1.47) and diabetes (1.68; 95% CI 1.45-1.94) than never smokers. Similarly, dual users also had increased odds of prediabetes (pooled odds ratio, 1.26; 95% CI 1.13-1.39) and diabetes (1.93; 95% CI 1.63-2.29). The strength of these associations was comparable to that of cigarette smokers. We observed significantly higher HbA1c and fasting blood glucose levels among both exclusive HTP users and dual users compared to never smokers. CONCLUSION HTP use was associated with an increased likelihood of prediabetes and diabetes. Prospective studies are warranted to confirm the cross-sectional association.

Abstract
BACKGROUND Heated tobacco products (HTPs) are often marketed as a safer alternative to help cigarette smokers quit. We investigated the link between HTP use and smoking cessation and relapse. METHODS 7044 adults (≥20 years old) with at least two observations over three waves (2019-2021) of a longitudinal, nationwide, internet-based survey were classified into current (past 30-day), former and never cigarette smokers. ≥1 month and ≥6 months smoking cessation and smoking relapse at 1-year follow-up were assessed in relation to current HTP use at baseline. Generalised estimating equation models were weighted to account for population differences between HTP users and non-users. Adjusted prevalence ratios (APRs) were computed within population subgroups. RESULTS At baseline, 17.2%, 9.1% and 6.1% of the respondents were current cigarette smokers, HTP users and dual users, respectively. Among current established smokers (having smoked regularly, n=1910), HTP use was significantly associated with a decreased likelihood of ≥1 month cessation within those who reported having used evidence-based cessation measures (APR=0.61), smoking 20+ cigarettes per day (APR=0.62), high school education or less (APR=0.73) and fair/poor health (APR=0.59). Negative associations were also seen for ≥6 months cessation among those aged 20-29 years (APR=0.56) and full-time workers (APR=0.56). Among former smokers (n=2906), HTP use was associated with smoking relapse within those who last smoked >1 year ago (APR=1.54), among women (APR=1.61), those aged 20-29 years (APR=2.09), those reporting high school education or less (APR=2.36), those who were unemployed/retired (AOR=3.31) and never/non-current alcohol users (APR=2.10). CONCLUSION HTP use did not help smokers quit or prevent former smokers from relapsing. HTPs should not be recommended as a cessation aid.

Abstract
Heated tobacco products (HTPs) have expanded globally. IQOS, a global HTP leader, was launched in Israel in 2016 and the US in 2019. To inform tobacco control efforts, it is critical to understand who is likely to use HTPs in different countries with distinct regulatory and marketing contexts. Thus, we conducted a cross-sectional survey among adult (ages 18-45) online panelists in the US (n = 1128) and Israel (n = 1094), oversampling tobacco users, in the fall of 2021, and used multivariable regression to identify correlates of (1) ever using IQOS; (2) past-month vs. former among ever users; and (3) interest in trying IQOS among never users. Among US adults, correlates of ever use included being Asian (aOR = 3.30) or Hispanic (aOR = 2.83) vs. White, and past-month use of cigarettes (aOR = 3.32), e-cigarettes (aOR = 2.67), and other tobacco (aOR = 3.34); in Israel, correlates included being younger (aOR = 0.97), male (aOR = 1.64), and cigarette (aOR = 4.01), e-cigarette (aOR = 1.92) and other tobacco use (aOR = 1.63). Among never users, correlates of greater interest included cigarette and e-cigarette use in the US (β = 0.57, β = 0.90) and Israel (β = 0.88, β = 0.92). IQOS use prevalence was low (US: 3.0%; Israel: 16.2%) but represented in vulnerable subpopulations (younger adults, racial/ethnic minorities).

Abstract
Limited data exist on the awareness, beliefs, and use of heated tobacco products (HTPs). Data from 1583 U.S. adult (age ≥ 21 years) current tobacco users were collected in 2021. Participants self-reported HTP awareness, beliefs, use, and susceptibility, as well as current tobacco product use and sociodemographics. We used weighted logistic and multinomial regression models to explore their associations. Overall, 23.6% were aware of, 8.9% had ever used, and 3.0% currently used HTPs. Younger individuals (vs. 61+ years), those with annual income $50,000+ (vs. <$50,000), and those currently using electronic vaping products (vs. non-users) were more likely to be aware of, to have ever used, and to currently be using HTPs (p < 0.05). Black individuals (vs. White) were more likely to report ever and current HTP use (p < 0.05). Current cigarette smoking was not associated with HTP awareness and use (p > 0.05). Holding favorable HTP beliefs was associated with susceptibility to and more advanced HTP use statuses (p < 0.05). Sociodemographics associated with HTP use may reflect HTP marketing strategies. The lack of association with cigarette smoking suggests HTPs may be unlikely cigarette substitutes. Addressing favorable HTP-related beliefs may prevent dual use.

Abstract
The objectives of this clinical study were to demonstrate a reduction in exposure to selected harmful and potentially harmful constituents (HPHCs) in Japanese healthy adult smokers who switched to four in-market heated tobacco products. Eighty-nine smokers were randomly assigned for five days to one of six study groups: four groups who switched to one of the commercially available heated tobacco products; a group who continued to smoke their own brand of combustible cigarettes (CC); or a group who stopped smoking (SS). Fifteen biomarkers of exposure (BoE) to 14 HPHCs and pyrene were measured at baseline, Day 3 and Day 5 in 24 h urine and breath, under clinical confinement. Product consumption, nicotine uptake and subjective effects were also measured before and after product switching. On Day 5, significant reductions in most BoE relative to the CC group were observed after switching to heated tobacco products. No changes in BoE were observed between baseline and Day 5 in the CC group. Significantly, the magnitude of the reduction in exposure to most of the selected HPHCs observed in the heated tobacco product groups was close to that observed in the SS group.

Abstract
Markets for nicotine vaping products (NVPs) and heated tobacco products (HTPs) have grown as these products became positioned as harm-reduction alternatives to combusted tobacco products. Herein, we present a public health decision-theoretic framework incorporating different patterns of HTP, NVP, and cigarette use to examine their impacts on population health. Our framework demonstrates that, for individuals who would have otherwise smoked, HTP use may provide public health benefits by enabling cessation or by discouraging smoking initiation and relapse. However, the benefits are reduced if more harmful HTP use replaces less harmful NVP use. HTP use may also negatively impact public health by encouraging smoking by otherwise non-smokers or by encouraging initiation or relapse into smoking. These patterns are directly influenced by industry behavior as well as public policy towards HTPs, NVPs, and cigarettes. While substantial research has been devoted to NVPs, much less is known about HTPs. Better information is needed to more precisely define the health risks of HTPs compared to cigarettes and NVPs, the relative appeal of HTPs to consumers, and the likelihood of later transitioning to smoking or quitting all products. While our analysis provides a framework for gaining that information, it also illustrates the complexities in distinguishing key factors.

Abstract
We aimed to assess the association between heated tobacco product (HTP) use and high-density lipoprotein cholesterol (HDL-C) concentration. Our study included 12,268 workers from five companies (Study I) and 36,503 workers from another large company (Study II). Participants were categorized into five groups: never smokers, past smokers, exclusive HTP users, dual users of cigarettes and HTPs, and exclusive cigarette smokers. We analyzed the data of Studies I and II separately and then pooled these estimates using a fixed-effect model. Of the 48,771 participants, 9.3% were exclusive HTP users, and 6.0% were dual users. Exclusive HTP users had modestly but significantly lower concentrations of HDL-C than never smokers, with the pooled mean difference being - 1.1 (95% CI - 1.5 to - 0.6) mg/dL. Dual users showed a further reduction (mean difference - 3.7 (- 4.2 to - 3.2) mg/dL), which was comparable to that of exclusive cigarette smokers versus never smokers (mean difference - 4.3 (- 4.7 to - 3.9) mg/dL). The pooled odds ratios (95% CIs) of having low HDL-C (< 40 mg/dL for men and 50 mg/dL for women) were 1, 0.99 (0.90-1.11), 1.25 (1.09-1.43), 2.02 (1.76-2.32), and 2.09 (1.88-2.32) for never smokers, past smokers, exclusive HTP users, dual users, and exclusive cigarette smokers, respectively. In conclusion, exclusive HTP users had lower HDL-C concentrations than never smokers, although higher than exclusive cigarette smokers. Moreover, dual users had HDL-C concentrations similar to those in exclusive cigarette smokers.

Abstract
In some private companies, “time-based” workplace policies which ban smoking during working hours (including or excluding lunchtime) have been implemented. Little is known about the relationship between time-based smoke-free policies for working hours and combustible cigarette and HTP use. In this study, we focused on workplace bans on smoking during working hours including or excluding lunchtime. Bans on smoking during working hours which include lunchtime may be successful in reducing use of combustible cigarettes and HTPs, but allowing their use during lunchtime may reduce the effectiveness of the ban. Not only place-based, but also time-based smoke-free policies are important for tobacco control in the workplace.
Although some private companies have implemented “time-based” workplace smoking bans covering all working hours including lunchtime, little is known about their impact on tobacco use. We examined associations between workplace smoking bans during working hours (including and excluding lunchtime) versus no ban and workers’ combustible cigarette and heated tobacco product (HTP) use. We used data from the Japan “Society and New Tobacco” Internet Survey 2020 and in total 4,222 workers aged 20–74 were included in the analyses. Using inverse probability weighting, prevalence ratios (PRs) and 95% confidence interval (CI) for tobacco use were calculated according to “time-based” smoke-free policies: workplace smoking bans for working hours including lunchtime (lunchtime ban), workplace smoking ban for working hours excluding lunchtime (lunchtime allowed), and no ban for working hours (no ban). The PRs of “lunchtime ban” for workers’ use of combustible cigarettes and HTPs were lower than “no ban”: 0.43 (CI: 0.29, 0.63) for combustible cigarette use and 0.61 (CI: 0.41, 0.90) for HTPs use. Meanwhile, the PRs for “lunchtime allowed” was not significant: 0.84 (CI: 0.70, 1.01) for combustible cigarettes use and 1.15 (CI: 0.94, 1.40) for HTPs use. Workplace bans on smoking during working hours which include lunchtime may successfully reduce workers’ combustible cigarette and HTP use, but allowing their use during lunchtime may reduce the effectiveness of the ban. Not only conventional “place-based” smoke-free policies, but also “time-based” smoke-free policies are useful for tobacco control in the workplace.

Abstract
The actual use of heated tobacco products (HTPs) among smokers with rheumatoid arthritis (RA) is little known. The objective of this study was to clarify the prevalence and reasons for HTP use among smokers with RA. We administered a web survey to a research company panel in Japan between December 2020 and January 2021. After 170,000 panelists completed a primary questionnaire regarding smoking and disease status, 198 smokers with RA completed a secondary questionnaire regarding the reasons for HTP use and perceptions about the harmfulness of HTPs. The primary questionnaire revealed that smokers with RA were more likely to use HTPs than smokers without RA, and the adjusted odds ratio of RA for HTP use was one of the highest factors among other diseases (adjusted OR: 2.34, 95% CI: 1.92-2.85, p < 0.001). The secondary questionnaire revealed that 43.7% of HTP smokers with RA had considered using HTPs due to their RA, and 42.0% of them felt that starting HTPs relieved the symptoms of RA. These results indicated that smokers with RA tend to start using HTPs due to their RA, despite the lack of evidences that HTPs are safer alternatives.

Abstract
Combustible cigarette smoking impacts fetal growth during pregnancy. However, the risk associated with heated tobacco products (HTPs) remains unclear. This nationwide cross-sectional study investigated whether HTP use during pregnancy is associated with small for gestational age (SGA) outcomes among 5647 post-delivery women with singleton pregnancies, which were divided into four groups: lifetime never-smokers, former smokers before pregnancy, and current smokers for each of the tobacco products during pregnancy (sole HTP and sole combustion smokers). Information on the prevalence of SGA, defined as birth weight and height below the 10th percentile, was retrieved from the Maternal and Child Health Handbooks of post-delivery women. Using logistic regression, the association between sole HTP smokers during pregnancy and SGA, adjusted for covariates, with lifetime never-smokers as reference, was investigated. The prevalence was: current sole HTP smokers during pregnancy, 1.8% (102/5647); and SGA, 2.9% (164/5647). Sole HTP smokers during pregnancy had a higher prevalence of SGA (5.9% [6/102] vs. 2.7% [111/4144]) with an adjusted odds ratio (OR) of 2.50 (95% confidence interval [CI], 1.03-6.05) than lifetime never-smokers. Among sole combustion smokers, the adjusted OR for SGA was 1.95 (95% CI, 0.81-4.67). In Japan, HTP smoking during pregnancy may be associated with an increased risk for SGA.

Abstract
We report cessation behaviors, reasons for use of electronic cigarettes (EC) and heated tobacco products (HTP) and association of their use with quit attempts and smoking intensity using Romania Global Adult Tobacco Survey 2018. Weighted estimates of EC and HTP by cigarette smoking (CS) status were assessed. Quit attempts, intention to quit, reasons for lack of intention to quit among current CS, and reasons for current use of EC and HTP were estimated. The association of 'ever use' of EC and HTP with cigarette smoking intensity and quit attempts was explored using binary logistic regression. Of the total 4571 surveyed, 1243 (27.3%) were current CS, 300 (24.4%) made quit attempts in the past 12 months. Only 38 (12.5%) and 26 (8.6%) had used EC and HTP as an aid to quit. Among current CS, 512 (41.2%) had no intention to quit. Reasons for this were, 'enjoy smoking' (86.1%), 'reduce stress' (65.9%), and 'staying alert' (46.3%). Awareness and use of EC and HTP were significantly higher among current CS. 'Dual use' of EC and HTP with CS was manifolds higher than stand-alone use. Reasons for current use of EC and HTP were 'enjoyment', and 'use in places where smoking was prohibited'.

Abstract
OBJECTIVES Promoting smoke-free policies is a key intervention for reducing secondhand smoke (SHS) exposure. During the COVID-19 pandemic in Japan, many indoor smoking spaces in workplaces were closed. This study aimed to reveal the association between a workplace smoke-free policy and SHS exposure among non-smoking employees, distinguishing between SHS exposure from cigarettes and exposure to secondhand heated tobacco product (HTP) aerosol, which have recently become popular in Japan. DESIGN AND SETTING We used data from the Japan COVID-19 and Society Internet Survey conducted in August-September 2020. PARTICIPANTS Among the 25 482 eligible respondents, 8196 non-smoking employees were analysed. PRIMARY OUTCOME MEASURE Multivariable logistic regression models were used to examine the impact of smoke-free policies in the workplace. RESULTS Compared with complete smoking bans, the ORs and 95% CIs for workplace SHS exposure at least once a week from cigarettes were 2.06 (95% CI: 1.60 to 2.65) for partial bans with no longer available smoking spaces, 1.92 (95% CI: 1.63 to 2.25) for partial smoking bans with still available smoking spaces and 5.33 (95% CI: 4.10 to 6.93) for no smoking bans. The corresponding ORs and 95% CIs for exposure to secondhand HTP aerosol were 4.15 (95% CI: 3.22 to 5.34), 2.24 (95% CI: 1.86 to 2.71) and 3.88 (95% CI: 2.86 to 5.26), respectively. CONCLUSIONS The effect of partial bans was limited, and temporary closure of smoking spaces might contribute to increased exposure to secondhand HTP aerosol. Complete smoking bans in the workplace were reaffirmed to be the best way to reduce SHS exposure from cigarettes and exposure to secondhand HTP aerosol.

Abstract
Tobacco, nicotine and related products have and continue to change rapidly, creating new challenges for policies regulating their advertising, promotion, sponsorship and sales. This paper reviews recent commercial product offerings and the regulatory challenges associated with them. This includes electronic nicotine delivery systems, electronic non-nicotine delivery systems, personal vaporisers, heated tobacco products, nicotine salts, tobacco-free nicotine products, other nicotine products resembling nicotine replacement therapies, and various vitamin and cannabis products that share delivery devices or marketing channels with tobacco products. There is substantial variation in the availability of these tobacco, nicotine, vaporised, and related products globally, and policies regulating these products also vary substantially between countries. Many of these products avoid regulation by exploiting loopholes in the definition of tobacco or nicotine products, or by occupying a regulatory grey area where authority is unclear. These challenges will increase as the tobacco industry continues to diversify its product portfolio, and weaponises 'tobacco harm reduction' rhetoric to undermine policies limiting marketing, promotion and taxation of tobacco, nicotine and related products. Tobacco control policy often lags behind the evolution of the industry, which may continue to sell these products for years while regulations are established, refined or enforced. Policies that anticipate commercial tobacco, nicotine and related product and marketing changes and that are broad enough to cover these product developments are needed.

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
BACKGROUND The point-of-sale (POS) is adapting to marketing restrictions, societal changes and the inclusion of new products, such as heated tobacco products (eg, Philip Morris International's (PMI) IQOS device and HEETS sticks). We aimed to assess (1) PMI's influences on IQOS/HEETS POS marketing and (2) the implications of the new legislation (POS display ban and plain packaging) for retailers. METHODS A cross-sectional survey of 43 IQOS/HEETS POS owners/managers in five Israeli cities assessed POS and participant characteristics, marketing strategies, attitudes towards IQOS, and POS implications of the legislation and COVID-19, including industry reactions. Bivariate analysis explored differences between POS selling of the IQOS device versus POS selling of HEETS only. RESULTS A higher proportion of those carrying IQOS (n=15) (vs HEETS only) had special displays (100% vs 17.9%, p<0.001) and interacted with specific IQOS salespersons (73.3% vs 28.6%, p=0.013). Common promotions were financial incentives based on HEETS sales for retailers (37.5%) and price discounts on HEETS for customers (48.7%). Most indicated positive attitudes towards IQOS (72.1%; eg, 'less harmful'), opposition to the legislation (62.7%), limited government assistance to implement the legislation (62.8%), and industry provision of display cases and/or signage to comply with the legislation (67.4%). CONCLUSION PMI uses similar tactics to promote IQOS at POS as they previously used for combustible products, including direct promotional activities with retailers, and circumvented legislation by using special displays and signage. Governments need to ban these measures and support retailers with clear practical guidance regarding the implementation of marketing restrictions at POS.

Abstract
To identify biomarkers of exposure present in Heated Tobacco Products (HTPs) users' urine which are associated with bladder cancer and to compare quantitative biomarker levels to those seen in combustible cigarette users. A systematic literature review was conducted in December 2020 with no date limits. Relevant studies that reported quantitative urinary biomarker of exposure in HTP users were included. Biomarkers and their parent compounds were classified by carcinogenicity according to the International Agency for Research on Cancer Monographs and were cross-referenced with the Collaborative on Health and the Environment Toxicant and Disease Database to determine associations with bladder cancer. Our literature search identified 561 articles and 30 clinical trial reports. 11 studies met inclusion criteria. These studies identified 29 biomarkers of exposure present in HTP users' urine, which reflect exposure to 21 unique parent compounds. Of these parent compounds, 14 are carcinogens and 10 have a known link to bladder cancer. HTP users' biomarkers of exposure were present at lower levels than combustible cigarette users but higher than never-smokers. Biomarkers of exposure to bladder carcinogens are present in the urine of HTP users. While levels of these biomarkers appear to be lower than combustible cigarette users, chronic urothelial exposure to bladder carcinogens is concerning and degree of bladder cancer risk remains unknown. Further long-term study is needed to elucidate the bladder cancer risk of HTP use.

Abstract
INTRODUCTION Heated tobacco products, including Marlboro IQOS, are available globally. In the USA, IQOS was authorised to be advertised with claims about reduced toxicant exposure relative to cigarettes. The effects of such modified risk claims and health warnings have not been studied among young adult cigarette smokers and non-smokers. METHODS In 2020, US young adult (18-30 years, n=1328) cigarette smokers and non-smokers viewed an IQOS ad in a 4 (modified risk claim variations or none) by 3 (warning variations or none) between-subjects experiment. Outcome measures assessed perceived credibility and effectiveness of the health or risk message for discouraging IQOS use, perceived harms, efficacy beliefs, and IQOS use intentions. RESULTS Smokers reported significantly higher (p<0.05) perceived credibility, lower perceived effectiveness, higher efficacy beliefs about switching to IQOS and higher intentions to use IQOS than non-smokers. Among smokers, health warnings increased perceived credibility (p<0.001) and effectiveness (p<0.05), but claims did not affect outcomes examined. Among non-smokers, warnings and claims increased perceived credibility, and warnings increased perceived effectiveness (p<0.003). The reduced exposure claim increased non-smokers' intentions to use IQOS (b=0.40, 95% CI 0.07 to 0.73). CONCLUSIONS Among young adult smokers, health warnings increased perceived effectiveness at discouraging IQOS use and perceived credibility. Among non-smokers, warnings and claims increased perceived credibility and warnings increased perceived effectiveness, but the Food and Drug Administration-authorised reduced exposure claim increased intentions to use IQOS. Research is warranted to understand how the content of modified risk claims and health warnings for IQOS affects IQOS use in this population.

Abstract
OBJECTIVES Knowledge on the impact of heated tobacco product (HTP) use in pregnant women with associated maternal and neonatal risks for hypertensive disorders of pregnancy (HDP) and low birth weight (LBW) is limited. We aimed to assess the status of HTP use among pregnant women in Japan and explore the association of HTP use with HDP and LBW. DESIGN Cross-sectional study. SETTING Data from the Japan 'COVID-19 and Society' Internet Survey study, a web-based nationwide survey. PARTICIPANTS We investigated 558 postdelivery and 365 currently pregnant women in October 2020. PRIMARY AND SECONDARY OUTCOME MEASURES Information on HDP and LBW was collected from the postdelivery women's Maternal and Child Health Handbooks (maternal and newborn records). We estimated the age-adjusted ORs and 95% CIs of ever HTP smokers for HDP and LBW and compared them with those of never HTP smokers in a logistic regression analysis. RESULTS The prevalence of ever and current HTP use were 11.7% and 2.7% in postdelivery women and 12.6% and 1.1% in currently pregnant women, respectively. Among currently pregnant women who were former combustible cigarette smokers, 4.4% (4/91) were current HTP smokers. Among postdelivery women, ever HTP smokers had a higher HDP incidence (13.8% vs 6.5%, p=0.03; age-adjusted OR=2.48, 95% CI 1.11 to 5.53) and higher LBW incidence (18.5% vs 8.9%, p=0.02; age-adjusted OR=2.36, 95% CI 1.16 to 4.87). CONCLUSIONS In Japan, the incidence of ever HTP use exceeded 10% among pregnant women, and HTP smoking may be associated with maternal and neonatal risks.

Abstract
Background: To gauge the public health impact of new nicotine products, information is needed on use among different populations. Aims were to assess in adults who smoked, vaped, did both or had recently stopped: (1) awareness, ever and current use of heated tobacco products (HTPs) and nicotine pouches (NP), (2) characteristics associated with ever use, (3) reasons for use of and satisfaction with HTPs, (4) characteristics associated with interest in use of HTPs. Methods: Online survey in the UK in 2019, n = 3883. (1) Proportion aware, ever and current (≥monthly) use; (2) ever use regressed onto socio-demographics and smoking/vaping; (3) frequency of reasons for HTP use and satisfaction; (4) interest in trying HTPs regressed onto socio-demographics and smoking/vaping status. Results: Awareness was 34.8% for HTP and 15.9% for NP; current use was 3.2% and 2.7%. Being <45 years, higher education, living in London and currently both smoking and vaping were associated with ever having used the products. Curiosity was the most common reason for HTP use (79.8%) and 72.0% of ever HTP users found them at least as satisfying as smoking. Among those not currently using HTPs, 48.5% expressed any interest-lower among those aged over 65 and higher among those smoking and vaping. Conclusions: In this sample of adults with a history of nicotine use, very few currently used heated tobacco products or nicotine pouches. Satisfaction with and interest in HTPs were substantial. The low level of use is unlikely to substantially reduce the public health impact of smoking.
