Reactions to a Hypothetical Ban of Open-System Electronic Cigarettes Among People Who Currently Use Electronic Cigarettes

INTRODUCTION

Policies limiting electronic cigarette (ECIG) device and liquid characteristics have been considered to prevent dependence potential and youth product appeal. "Open-system" ECIGs allow people to adjust device and liquid characteristics, which may undermine these policies. This study examined anticipated reactions to a policy prohibiting the sale of open-system ECIG devices in the United States using concept mapping.

METHODS

In 2020, adults who reported ECIG use in the past 30 days (n = 70; 45.1% women; mean age = 33.0, SD = 10.6) recruited from a research registry of individuals from across the United States provided statements into a shared list that completed a prompt: "If open-system vaping devices were no longer sold in the US and only closed-system vaping devices were available, what is a specific reaction or response you would have?" at a study website. Participants rated statements (1-7) on how true the statements were for them. Multidimensional scaling and hierarchical cluster analyses were used to identify thematic clusters. Mean ratings of statements were calculated and compared based on the type of ECIG used and current cigarette smoking status.

RESULTS

Participants generated 85 unique statements. The analysis identified eight themes that were organized into two broad groups. The first group of five clusters described behavioral responses to the hypothetical policy (Loopholes, Switch to Closed-System ECIGs, Legal Approaches to Use Open-System ECIGs, ECIG Use Cessation, Switch to non-ECIG Products). The second group of three clusters described psychological responses to the hypothetical policy (Closed-System ECIG Cons, Psychological Responses, Policy Outcome Concerns).

CONCLUSIONS

While a ban on open-system ECIG devices may have positive impacts on public health, policy loopholes, and consumer behaviors may undermine the policy. Efforts to support policy enforcement could increase policy effectiveness.

IMPLICATIONS

Open-system electronic cigarettes (ECIGs) that allow people who use ECIGs to modify ECIG device and liquid characteristics may limit the effectiveness of policies that establish product standards which attempt to limit nicotine delivery and flavor content in ECIG liquids. This study identified predicted reactions to a hypothetical policy prohibiting the sale of open-system ECIGs in the United States. Results suggest that people who use ECIGs may view a policy prohibiting open-system ECIGs unfavorably, but would be willing to use closed-system ECIGs. However, many ECIG users may attempt to find loopholes in the policy or alternative sources to purchase open-system ECIGs if open-systems were banned. Future research should identify strategies for tobacco regulatory policy enforcement to increase effectiveness.

Exploring Young Adults' Beliefs About Cigar Smoking by Susceptibility: A Belief Elicitation Study

INTRODUCTION

Young adults are at risk for cigar smoking, which is associated with cancers and pulmonary and cardiovascular diseases. Little is known about young adults' beliefs about smoking cigarillos, little filtered cigars, and large cigars, and how these beliefs may vary across cigar types and by cigar susceptibility.

AIMS AND METHODS

The larger study surveyed a U.S. sample of young adults (18-30 years old) who never used tobacco products (n = 948) through Qualtrics online panel services in August 2021-January 2022. We assessed participants' susceptibility to using different cigar types. Participants were randomly assigned to open-ended questions about one of the three cigar types to elicit behavioral, normative, and control beliefs. We conducted thematic analysis to code emergent themes within each belief and examined the frequency of reported themes at the intersection of cigar type and cigar susceptibility.

RESULTS

Cigar susceptible participants reported positive behavioral beliefs (eg, anticipated relaxation, mood regulation, being cool), friends as supportive referents, and easy-to-smoke control beliefs (eg, high accessibility, low cost) more frequently than non-susceptible participants. Varied frequency by cigar type also emerged. For example, cigarillo and little filtered cigar features were mentioned more frequently as easy-to-smoke control beliefs, while low accessibility was reported more frequently as a hard-to-smoke control belief for large cigars.

CONCLUSIONS

Findings identify salient beliefs about cigarillo, little filtered cigar, and large cigar smoking among young adult tobacco never-users. Future research should investigate the potential importance of these beliefs in cigar smoking susceptibility and initiation among young adults, and their potential utility in prevention research.

IMPLICATIONS

This thematic analysis identified salient beliefs about cigarillos, little filtered cigars, and large cigars among a U.S. young adult sample, and differentiated emergent beliefs by cigar susceptibility status and by cigar type. Given the lack of cigar smoking prevention media campaigns, identifying these beliefs is the one of the first steps in developing effective cigar smoking prevention strategies. Future quantitative studies are needed to confirm the relationships between these beliefs and smoking initiation of each cigar type to further inform the types of beliefs to be targeted in strategic communication and help prevent cigar smoking initiation among susceptible young adults.

Nicotine Dependence among Current Cigarette Smokers Who Use E-Cigarettes and Cannabis

BACKGROUND

Co-use of tobacco and cannabis and dual use of cigarettes and e-cigarettes are very common among young adults. However, it is unclear whether co-use of cigarettes, e-cigarettes, and/or cannabis is associated with higher levels of nicotine dependence than cigarette-only use. We investigated the relationship between cigarette/nicotine dependence and co-use of tobacco and cannabis among 4 groups of cigarette smokers aged 18-35: cigarette-only smokers, cigarette-e-cigarette (CIG-ECIG) co-users, cigarette-cannabis (CIG-CAN) co-users, and cigarette-e-cigarette-cannabis (CIG-ECIG-CAN) co-users.

METHODS

Data were from a 2018 cross-sectional survey based on a national convenience sample of smokers aged 18-35 (n = 315). Cigarette/nicotine dependence was measured by the Fagerstrom Test of Nicotine Dependence (FTND) and e-cigarette dependence was measured by the Penn State E-cigarette Dependence Index. Bivariate analyses examined sociodemographic and tobacco/other substance use characteristics by co-use status and multivariable linear regression assessed the relationship between co-use and nicotine dependence.

RESULTS

In the sample, 27.6% were cigarette-only smokers, 24.8% were CIG-ECIG, 27.6% were CIG-CAN, and 20.0% were CIG-ECIG-CAN co-users. Significant differences were observed in sociodemographic and tobacco/other substance use characteristics by co-use status. E-cigarette co-users had low e-cigarette dependence, but moderate FTND scores. In adjusted analyses, only CIG-ECIG co-use was associated with higher FTND scores compared to cigarette-only smoking. However, CIG-ECIG and CIG-ECIG-CAN co-use were associated with higher FTND scores compared to CIG-CAN co-use.

CONCLUSIONS

Co-use of cigarettes and e-cigarettes was associated with greater nicotine dependence among smokers aged 18-35. Additional research is needed to understand the underlying mechanisms of these relationships and inform prevention efforts.

Acute effects of flavored Black and mild cigars among young adult cigarette smokers

The U.S. Food and Drug Administration proposed new product standards that would ban characterizing flavors (other than tobacco) in cigars. To inform this regulatory action, we compared physiological effects, use behavior, and subjective effects of four popular cigar flavors in cigar-naïve young adult cigarette smokers. Across five laboratory visits, participants (n = 25) used and evaluated own brand (OB) cigarettes or Black & Mild cigars (original, wine, apple, and cream flavors). Linear mixed models tested differences in saliva nicotine, exhaled carbon monoxide (CO), heart rate (HR), blood pressure (BP), puff topography, and subjective effects (p < .05). Compared to all cigars, OB resulted in higher nicotine boost (953 vs. < 300 ng/ml) and lower CO boost (4 vs. 8-9 ppm). Nicotine boost for original cigars (283 ng/ml) was significantly higher than wine (190 ng/ml). All products significantly increased HR/BP relative to baseline, but across time wine and apple cigars were associated with significantly lower HR than OB and BP effects varied. Relative to OB, participants took approximately 0.5 s longer puffs for all cigars and took significantly larger puffs (+ 21%-24%) of original, wine, and apple cigars. OB was rated more positively than all cigars, which had similar subjective effects. Wine cigars were disliked most and were less effective in reducing tobacco abstinence symptoms than OB; cream cigars were harsher and had stronger flavor intensity than original. The consistency in toxicant exposure, use behavior, and subjective effects across cigar flavors, including original, highlights the need for product standards to interpret characterizing flavors subject to prohibition broadly.

Responses of African American Individuals Who Use Menthol Cigarettes to Potential Flavored Tobacco Bans

INTRODUCTION

The U.S. Food and Drug Administration has proposed new product standards regarding the availability of menthol cigarettes and flavored cigars in the U.S. However, it is unclear whether limiting characterizing flavors in cigarettes and cigars as proposed, or across all tobacco products, produces differential effects on the tobacco use behaviors of African American/Black individuals who use menthol cigarettes. This study assessed whether limiting characterizing flavors in combusted products only or across all tobacco products produces differential impacts on the tobacco use behaviors of African American/Black individuals who use menthol cigarettes.

METHODS

Adult African American/Black individuals who use menthol cigarettes in the U.S. were recruited through Qualtrics (n=373) and in Richmond, VA (n=206) for an online experiment from September 2021 to August 2022. Participants reported how their tobacco use behaviors would change under 3 scenarios: maintenance of the status quo, limited flavor ban (ban characterizing flavors in cigarettes and cigars), and comprehensive flavor ban (ban characterizing flavors in all tobacco products). Seemingly unrelated regressions compared differences in expected responses to policy scenarios (p<0.05).

RESULTS

Both flavor ban scenarios resulted in higher quitting intentions for cigarettes and all tobacco products than the status quo (p<0.05). The comprehensive ban resulted in greater intentions to quit all tobacco products and lower intentions to switch to certain alternative products (e.g., E-cigarettes, smokeless tobacco, heated tobacco products) than the limited ban (p<0.05).

CONCLUSIONS

African American/Black individuals who use menthol cigarettes appear more likely to quit smoking if characterizing flavors in combusted products (e.g., menthol cigarettes) are banned, regardless of if characterizing flavors are available in noncombusted alternative tobacco products.

Factors associated with smokefree rules in the homes of Black/African American women smokers residing in low-resource rural communities

Little is known about the implementation of voluntary policies in the homes of Black/African American women smokers who live in rural areas where health care access is limited. This paper examines 1) the sample's prevalence of comprehensive smoke-free rules; 2) sociodemographic, social, and smoking characteristics of women by home rule type; and 3) the association of social indicators with the outcome complete ban on smoked tobacco use in the home (n = 191). Families Rising to Enforce Smokefree Homes collected baseline data from 2019 to 2021 prior to randomization to an intervention that aimed to increase comprehensive smokefree policies in the homes African American women living in the rural Delta region of Arkansas. The primary outcome was implementation of a complete ban on all smoked tobacco products anywhere inside the home. Results showed that 26% of women had a rule that completely banned all smoked tobacco products in the home. Women who reported having no ban were more likely to be employed part-time (50.0%), while women with a partial (66.9%) or complete ban (60.0%) were more likely to not currently work for pay. Women who indicated that they just meet basic expenses and meet needs with little left had significantly lower odds of having a complete ban on smoked tobacco in the home than women who indicated that they live comfortably. Perceived financial security may be a motivating factor that helps women keep their homes free from all smoked tobacco products (# NCT03476837).

Centering racial justice for Black/African American and Indigenous American people in commercial tobacco product regulation

Although overall health in the United States (US) has improved dramatically during the past century, long-standing health inequities, particularly the unequal and unjust burden of tobacco-related disease and death among racialized populations, persist. A considerable gap exists in our understanding of how commercial tobacco product regulations and policies cause and/or exacerbate race-based health inequities among Black/African American (B/AA) and Indigenous American people. The purpose of this paper is to 1) describe how existing US commercial tobacco regulatory policies may contribute to structural racism and undermine the full benefits of tobacco prevention and control efforts among B/AA and Indigenous American groups; and 2) initiate a call to action for researchers and regulators of tobacco products to examine policies using an equity lens. These actions are imperative if empirically-informed regulation of commercial tobacco products is to address health equity.

Electronic cigarette users' reactions and responses to a hypothetical ban of flavoured electronic cigarette liquids

Regulations have been proposed to limit e-cigarette flavours, but limited research has examined potential impacts of such policies. This study examined adult e-cigarette users’ reactions to a hypothetical e-cigarette flavour ban.

Behavioral economic assessment of abuse liability for Black & Mild cigar flavors among young adults

Cigars are available in a variety of flavors that may impact uptake and use, but little is known about how different flavors affect abuse liability. This study used 3 behavioral economic tasks to examine abuse liability of Black & Mild cigars differing in flavor among young adult cigarette smokers. Participants were 25 cigar-naïve young adults (aged 18-25 years) who smoked ≥ 5 cigarettes/day. In 5 Latin square-ordered laboratory visits, participants completed 3 abuse liability tasks (drug purchase task, cross-price purchase task, and multiple-choice procedure) for each of 4 cigar flavors (original, cream, wine, or apple) and own-brand cigarettes. In the drug purchase task, relative to own-brand cigarettes, all cigar flavors were associated with lower abuse liability using most measures (intensity, breakpoint, maximum total tobacco expenditure for 1 day [ps < .05]), although only wine-flavored cigars scored significantly lower using 1 measure (price at maximum total tobacco expenditure for 1 day). When cigars and cigarettes were available concurrently in the cross-price purchase task, all cigar flavors functioned as substitutes for cigarettes. Using the multiple-choice procedure, crossover points for wine- (mean = $0.61) and apple-flavored cigars (mean = $0.71) were significantly lower than own-brand cigarettes (mean = $0.86) and original-flavored cigars (mean = $1.00); no significant differences existed between own-brand cigarettes and original-flavored cigars. Thus, whereas abuse liability may be highest for participants' own-brand cigarette, young adult smokers may be willing to use flavored cigars. Furthermore, abuse liability varies by cigar flavor, with original- and cream-flavored cigars appearing to have the highest abuse liability. Characterizing flavors and flavor additives in cigars represent an important tobacco regulatory target. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

Characterization of Electronic Cigarette Warning Statements Portrayed in YouTube Videos

INTRODUCTION

In 2018, the United States Food and Drug Administration (FDA) required that electronic cigarette (e-cigarette) manufacturers, packagers, importers, distributors, and retailers display an addictive or alternate warning statement on e-cigarette visual advertisements. Few studies have investigated the FDA-mandated and other warnings on social media. This study examined the prevalence and content of warning statements in e-cigarette-related YouTube videos.

METHODS

In 2019, The Virginia Commonwealth University Center for the Study of Tobacco Products conducted bi-monthly (February-June) YouTube searches by relevance and view count to identify e-cigarette-related videos. Overall, 178 videos met the inclusion criteria. Staff coded each video for the presence of a visual/verbal warning statement, warning statement type (eg, FDA-mandated, addiction/tobacco, safety/toxic exposure, health effects), sponsorship, and tobacco product characteristics. A data extraction tool collected the video URL, title, upload date, and number of views, likes/dislikes, and comments.

RESULTS

Only 5.1% of videos contained FDA-mandated and 21.9% contained non-mandated warnings. All videos with FDA-mandated and 46.2% of non-mandated warnings were represented visually. Only 13.1% of industry-sponsored videos uploaded after the mandate effective date had an FDA-mandated warning statement and videos with FDA-mandated and non-mandated (v. no) warnings had significantly fewer views, likes, dislikes, and comments. Among all non-mandated warnings, 31.3% featured an addiction/tobacco, 18.8% a safety/toxic exposure, and 37.5% a health effects warning.

CONCLUSIONS

The prevalence of FDA-mandated warning statements in e-cigarette related YouTube videos was low. FDA enforcement of the warning statement mandate on YouTube could increase the public's understanding of the addictive nature of nicotine in e-cigarettes.

IMPLICATIONS

The FDA has the authority to regulate the advertisement and promotion of e-cigarettes on the Internet. These data can inform future FDA requirements related to the language content and visual representation of addiction/tobacco, safety/exposure, and health effects warning statements that appear in YouTube videos and other visual social media popular among young people. Such data would help consumers make informed decisions about purchasing e-cigarette products, using e-cigarettes, and avoiding unintentional harm related to e-cigarettes. In addition, these data may help social media platforms make decisions on whether they will prohibit advertisements that promote or facilitate the sale of tobacco products.

Cigar-Smoking-Cessation Interest and Experience among Black Young Adults: A Semi-Structured In-Depth Interview Investigation

Although Black/African American populations have high cigar-smoking prevalence, little is known about cigar-smoking cessation among this group. This study explored the perceptions and experiences of cigar-smoking cessation and assistance received from healthcare providers among forty Black young-adult cigar smokers (ages 21-29). Semi-structured in-depth phone interviews were transcribed and coded. Qualitative data were analyzed by using thematic analysis. Participants mostly smoked cigarillos, large cigars, and blunts. Overall, many regular cigarillo smokers reported interest in quitting eventually, while large-cigar and blunt smokers shared less interest in quitting because they perceived low harm from smoking these products. The reasons for cigar-smoking cessation were health concerns and financial constraints. Most of the participants who attempted to quit cigars did not use any cessation aids. The reasons for relapse included nicotine withdrawal, stress, and easy access. Additionally, most participants reported their healthcare providers did not ask whether they smoked cigars, and even when they knew, little assistance for cigar-smoking cessation was provided. Informing Black cigar smokers of the harm of cigar smoking and encouraging healthcare providers to screen for and assist with cigar-smoking cessation may alleviate the health burden of cigar smoking in this population.

Exploring changes in cigar smoking patterns and motivations to quit cigars among black young adults in the time of COVID-19

INTRODUCTION

The COVID-19 pandemic has disproportionately impacted the Black/African American communities in the U.S. The objective of this study is to understand the change in cigar smoking patterns and motivations to quit cigars during the COVID-19 pandemic among Black young adult cigar smokers.

METHODS

During May-June 2020, in-depth telephone interviews were conducted to investigate cigar (i.e., large cigars, cigarillos, filtered cigars, and blunts) smoking behaviors during the pandemic among self-identified, non-Hispanic Black/African American young adult cigar smokers (n = 40; ages 21-29). Interviews were audio-recorded, transcribed verbatim, and coded separately by three coders. Thematic analysis was used to assess thematic patterns arising from the interviews.

RESULTS

Most participants reported smoking cigarillos and blunts in higher frequency and quantity to cope with COVID-19-induced stress, anxiety, loneliness, and boredom due to economic losses and physical isolation. Some also reported contextual changes in cigarillo and blunt smoking, including smoking around the clock, smoking immediately after waking up, and smoking an entire cigarillo or blunt in one setting. Very few participants reported motivations to quit cigars during the pandemic. Perceiving higher risks of progressed COVID-19 outcomes did not prompt participants' increased motivations for quitting cigars.

CONCLUSIONS

Black young adults in this study increasingly smoked cigarillos and blunts during the COVID-19 pandemic, mainly attributed to daily life stressors. Participants did not have increased motivations for quitting cigars to reduce COVID-19-related risks. Promoting contextually appropriate healthy coping and cigar smoking cessation may minimize COVID-19-related health consequences of cigar smoking and reduce health disparities among Black young adults.

Orthodox and Unorthodox Uses of Electronic Cigarettes: A Surveillance of YouTube Video Content

INTRODUCTION

Open electronic cigarette (e-cigarette) systems are customizable by consumers and often allow for potential "unorthodox" use of the product; that is, use not as intended by the manufacturer. Little is known about the types and prevalence of unorthodox uses and how these practices are transmitted via popular social media.

METHODS

Monthly searches of YouTube were conducted from June through November 2016 using the following search terms: "e-cigarettes," "vaping," and "e-juice." After collecting static and dynamic data on the 150 videos identified, two coders independently coded videos for general information, unorthodox use behaviors, health claims, and production quality and characteristics for orthodox and unorthodox use. Intercoder reliability was high (Cohen's κ 0.81, p < .001).

RESULTS

One hundred fifty videos were included in the study with a total of 115 551 563 views. We identified nine categories of unorthodox uses of e-cigarettes. Unorthodox use was three times as prevalent as orthodox use. Seventy-seven percent of the unorthodox use videos included recreational e-cigarette use, 57% included modification of mechanical parts and components, and 44.6% included unorthodox substance application (dripping). There were more than twice as many social media links in videos depicting unorthodox compared to orthodox use, but the level of engagement was lower for unorthodox use.

CONCLUSIONS

E-cigarette unorthodox use on YouTube is more prevalent than orthodox use, suggesting the need to further investigate the prevalence of unorthodox use among e-cigarette users and the influence of social media on consumer uptake of unorthodox and orthodox uses of e-cigarettes.

IMPLICATIONS

The US Food and Drug Administration has regulatory authority over e-cigarettes, parts and components. Many e-cigarettes currently marketed are open systems. Closed systems may allow less manipulation and may influence the safety of these products. This study provides valuable information on ways that open system e-cigarettes are used and it can inform safety tests that can be conducted by the US Food and Drug Administration to determine whether or not these products should remain on the market. In addition, our definitions of unorthodox use can be incorporated into the Population Assessment of Tobacco on Health Study to better understand the prevalence of these behaviors.

Racial discrimination and alcohol problems among African American young adults: Examining the moderating effects of racial socialization by parents and friends

OBJECTIVE

Racial discrimination is a stressor that may put African Americans at risk for alcohol use and related problems. We examined whether experiences of blatant (racist events) and subtle (racial microaggressions) forms of racial discrimination were associated with alcohol consumption and alcohol problems among African American young adults, and whether childhood/adolescence racial socialization by parents and friends moderated these associations.

METHOD

The sample included 383 African American young adults (Mage = 20.65, SD = 2.28; 81% female) who completed an electronic survey in Fall, 2017. Hierarchical linear regression analyses were conducted in Mplus.

RESULTS

Experiences of racist events and racial microaggressions were associated with higher levels of alcohol consumption and more alcohol problems. Racial socialization by friends, but not parents, moderated these associations. Specifically, cultural socialization by friends buffered the effect of racist events on alcohol consumption and alcohol problems, whereas promotion of mistrust by friends exacerbated the effect of racial microaggressions on alcohol problems.

CONCLUSIONS

Both blatant and subtle forms of racial discrimination were associated with higher risk for alcohol use or problems among African American young adults. Racial socialization by friends while growing up may play an important role in alcohol use outcomes during young adulthood. Findings highlight the importance of considering different forms of racial discrimination and emphasize the unique roles of racial socialization across different social contexts (i.e., parent and peers or friends) in relation to psychosocial outcomes among African American individuals.

Hookah Use Among US Youth: A Systematic Review of the Literature From 2009 to 2017

INTRODUCTION

Given the US Food and Drug Administration (FDA)'s authority to regulate hookah, more research is needed to inform regulations intended to prevent youth from using hookah. This systematic review summarizes and assesses the literature related to hookah use among adolescents (11 to ≤18 years of age) in the United States from 2009 to 2017.

METHODS

Database searches yielded 867 peer-reviewed articles. After duplicates were removed, authors reviewed 461 articles for inclusion. Included articles (n = 55) were coded for study themes, study quality, and their relevance to FDA's research priorities. A qualitative synthesis is presented.

RESULTS

The following themes were identified: (1) prevalence of hookah use (n = 42), (2) tobacco use transitions (n = 7), (3) sociodemographic correlates (n = 35), (4) psychosocial risk factors (n = 21), (5) concurrent use of other tobacco products (n = 31), (6) concurrent use of other substances (n = 9), and (7) other (n = 15)-which includes low prevalence themes. The qualitative synthesis showed increasing rates of hookah use. Older age, male gender, positive social normative beliefs, higher peer use, as well as lower perceived risk were associated with hookah use. Longitudinal studies of youth hookah use showed bidirectional relationships between use of hookah and other tobacco products. All articles fell within FDA's research priority related to "behavior," and three priorities ("impact analysis," "health effects," and "toxicity") have not been explored for hookah use among US youth since 2009.

CONCLUSIONS

The prevalence of hookah use among youth in the United States is increasing, thus more research is needed to inform policies targeted to protect this vulnerable population.

IMPLICATIONS

This study represents a novel contribution to our understanding of hookah use among youth in the United States from 2009-the year that the Family Smoking Prevention and Tobacco Control Act was passed-to 2017. In recent years, hookah has become a more popular tobacco product among US youth; however, to date, no systematic reviews of hookah use among this population exist. Results highlight implications for future US FDA regulatory policy and identify gaps in research to be addressed in future studies.

Warning Statements and Safety Practices Among Manufacturers and Distributors of Electronic Cigarette Liquids in the United States

Introduction

Prior to the US Food and Drug Administration's (FDA) regulation of electronic cigarettes and warning statements related to nicotine addiction, there was no critical examination of manufacturer/distributor voluntary practices that could potentially inform FDA actions aimed to protect consumers. This study examined the content of warning statements and safety characteristics of electronic cigarette liquid bottles using a national sample.

Methods

Research staff randomly selected four electronic cigarette liquid manufacturers/distributors from four US geographic regions. Staff documented the characteristics of product packaging and content of warning statements on 147 electronic cigarette liquids (0-30 mg/ml of nicotine) purchased online from 16 manufacturers/distributors in April of 2016.

Results

Data showed that 97.9% of the electronic cigarette liquid bottles included a warning statement, most of which focused on nicotine exposure rather than health. Only 22.4% of bottles used a warning statement that indicated the product "contained nicotine." Of bottles that advertised a nicotine-based concentration of 12 mg/ml, 26% had a warning statements stated that the product "contains nicotine." None of the statements that indicated that the product "contained nicotine" stated that nicotine was "addictive." All bottles had a safety cap and 12% were in plastic shrink-wrap. Fifty-six percent of the websites had a minimum age requirement barrier that prevented under-aged persons from entering.

Conclusions

Most manufacturers/distributors printed a warning statement on electronic cigarette liquid bottles, but avoided warning consumers about the presence and the addictiveness of nicotine. Studies are needed to examine manufacturer/distributor modifications to product packaging and how packaging affects consumer behaviors.

Implications

These data can inform future FDA requirements related to the packaging and advertising of e-cigarette liquids; regulation related to the content of warning statements, including exposure warning statements, which are not currently mandated; and requirements on websites or language on packaging to help manufacturers adhere to the minimum age of purchase regulation. The data can also be used to help FDA develop additional guidance on the framing of statements on packaging that helps consumers make informed decisions about purchasing the product or protecting young people from use or unintentional exposure to the product.

Harm Perceptions of Alternative Tobacco Products among US Adolescents

OBJECTIVES

In this study, we identified groups of adolescents who share similar awareness and perceptions of harm regarding e-cigarettes, cigars, hookah, and smokeless tobacco.

METHODS

We used latent class analyses (LCA) with the data from Wave 1 (2013-14) of the Population Assessment of Tobacco and Health youth and parent survey (PATH; N = 13,650) to address the research goal. Multinomial logistic regression analysis assessed the associations between identified classes with demographic characteristics and tobacco use.

RESULTS

LCA identified 5 classes: (1) perceived harm across all alternative tobacco products (36.6%); (2) perceived harm for e-cigarettes and smokeless tobacco but never heard of cigars and hookah (48.2%); (3) never heard of alternative tobacco products (8.6%); (4) mix of no harm and harm across alternative tobacco products (5.2%); and (5) "don't know" the harm across alternative tobacco products (1.4%). Relative to the class who perceived harm across all alternative tobacco products, classes of adolescents who were unaware of the products or did not know the harms were more likely to be non-white, younger, have lower parental education, and less likely to have tried an alternative tobacco product.

CONCLUSIONS

Tobacco prevention should target vulnerable youth, such as adolescents who are non-white, young, and have low parental education.

A longitudinal analysis of electronic cigarette forum participation

Electronic cigarette (e-cigarette) Internet forums are social networking websites that allow members around the world to share information and personal experiences about e-cigarettes. However, little is known about their popularity and reach. This longitudinal study investigated indicators of participation (membership, number of discussion boards, and number of message posts) in 77 e-cigarette forums from February 2016 to January 2017. Autoregressive time-series analyses were used to assess monthly changes in participation among small (<1000 members), medium (1000-5000 members), and large (>5000 members) forums that were active at all 12 observation time points. Paired sample t-tests were conducted to compare changes in participation before and after the U.S. Food and Drug Administration announced the regulation of e-cigarettes. Analyses revealed significant and consistent increases in forum membership (R²s > 0.72; ps < 0.01), discussion boards (R²s > 0.97; ps < 0.001), and message posts (R²s > 0.96; ps < 0.001) across all forum sizes during the 12-month period. No differences were found in participation indicators pre- and post-regulation announcement. E-cigarette forums provide real-time information on the levels of participation over time and therefore may be an important platform to study interactions among consumers and how these interactions shape e-cigarette knowledge, attitudes and use behaviors.

Triangulating abuse liability assessment for flavoured cigar products using physiological, behavioural economic and subjective assessments: a within-subjects clinical laboratory protocol

INTRODUCTION

In the USA, Food and Drug Administration regulations prohibit the sale of flavoured cigarettes, with menthol being the exception. However, the manufacture, advertisement and sale of flavoured cigar products are permitted. Such flavourings influence positive perceptions of tobacco products and are linked to increased use. Flavourings may mask the taste of tobacco and enhance smoke inhalation, influencing toxicant exposure and abuse liability among novice tobacco users. Using clinical laboratory methods, this study investigates how flavour availability affects measures of abuse liability in young adult cigarette smokers. The specific aims are to evaluate the effect of cigar flavours on nicotine exposure, and behavioural and subjective measures of abuse liability.

METHODS AND ANALYSES

Participants (projected n=25) are healthy smokers of five or more cigarettes per day over the past 3 months, 18-25 years old, naive to cigar use (lifetime use of 50 or fewer cigar products and no more than 10 cigars smoked in the past 30 days) and without a desire to quit cigarette smoking in the next 30 days. Participants complete five laboratory sessions in a Latin square design with either their own brand cigarette or a session-specific Black & Mild cigar differing in flavour (apple, cream, original and wine). Participants are single-blinded to cigar flavours. Each session consists of two 10-puff smoking bouts (30 s interpuff interval) separated by 1 hour. Primary outcomes include saliva nicotine concentration, behavioural economic task performance and response to various questionnaire items assessing subjective effects predictive of abuse liability. Differences in outcomes across own brand cigarette and flavoured cigar conditions will be tested using linear mixed models.

ETHICS AND DISSEMINATION

The Virginia Commonwealth University Institutional Review Board approved the study (VCU IRB: HM20007848). Dissemination channels for study findings include scientific journals, scientific meetings, and policy briefs.

Influence of Parental Alcohol Dependence Symptoms and Parenting on Adolescent Risky Drinking and Conduct Problems: A Family Systems Perspective

BACKGROUND

Parental alcohol problems are associated with adverse adolescent outcomes such as risky drinking and conduct problems. Important questions remain about the unique roles of fathers' and mothers' alcohol problems and differences and/or similarities in pathways of risk across ethnicity and gender. In this study, we used a family systems approach to consider spillover and crossover effects of fathers' and mothers' alcohol problems (number of alcohol dependence symptoms [ADS]) and parenting behaviors in relation to adolescents' risky drinking and conduct problems.

METHODS

The sample included 1,282 adolescents (aged 12 to 17) and their parents from the Collaborative Study on the Genetics of Alcoholism. Parents completed the Semi-Structured Assessment for the Genetics of Alcoholism (SSAGA), and adolescents completed an adolescent version of SSAGA. Data were analyzed using multivariate structural equation modeling.

RESULTS

Fathers' ADS count was associated with higher adolescent risky drinking and conduct problems indirectly via disruption to fathers' and mothers' positive parenting behaviors, whereas mothers' ADS count was not associated with adolescents' risky drinking and conduct problems directly or indirectly via positive parenting behaviors. No differences in these associations were found across ethnic background and offspring gender.

CONCLUSIONS

Findings highlight the importance of considering the unique roles of fathers' and mothers' ADS in influencing family processes and adolescent outcomes.

Sugar and Aldehyde Content in Flavored Electronic Cigarette Liquids

Introduction

Sugars are major constituents and additives in traditional tobacco products, but little is known about their content or related toxins (formaldehyde, acetaldehyde, and acrolein) in electronic cigarette (e-cigarette) liquids. This study quantified levels of sugars and aldehydes in e-cigarette liquids across brands, flavors, and nicotine concentrations (n = 66).

Methods

Unheated e-cigarette liquids were analyzed using liquid chromatography mass spectrometry and enzymatic test kits. Generalized linear models, Fisher's exact test, and Pearson's correlation coefficient assessed sugar, aldehyde, and nicotine concentration associations.

Results

Glucose, fructose and sucrose levels exceeded the limits of quantification in 22%, 53% and 53% of the samples. Sucrose levels were significantly higher than glucose [χ2(1) = 85.9, p < .0001] and fructose [χ2(1) = 10.6, p = .001] levels. Formaldehyde, acetaldehyde, and acrolein levels exceeded the limits of quantification in 72%, 84%, and 75% of the samples. Acetaldehyde levels were significantly higher than formaldehyde [χ2(1) = 11.7, p = .0006] and acrolein [χ2(1) = 119.5, p < .0001] levels. Differences between nicotine-based and zero-nicotine labeled e-cigarette liquids were not statistically significant for sugars or aldehydes. We found significant correlations between formaldehyde and fructose (-0.22, p = .004) and sucrose (-0.25, p = .002) and acrolein and fructose (-0.26, p = .0006) and sucrose (-0.21, p = .0006). There were no significant correlations between acetaldehyde and any of the sugars or any of the aldehydes and glucose.

Conclusions

Sugars and related aldehydes were identified in unheated e-cigarette liquids and their composition may influence experimentation in naïve users and their potential toxicity.

Implications

The data can inform the regulation of specific flavor constituents in tobacco products as a strategy to protect young people from using e-cigarettes, while balancing FDA's interest in how these emerging products could potentially benefit adult smokers who are seeking to safely quit cigarette smoking. The data can also be used to educate consumers about ingredients in products that may contain nicotine and inform future FDA regulatory policies related to product standards and accurate and comprehensible labeling of e-cigarette liquids.

User-identified electronic cigarette behavioral strategies and device characteristics for cigarette smoking reduction

BACKGROUND

There is limited evidence on how cigarette smokers use electronic cigarettes (ECIGs) for smoking cessation and reduction. This study used concept mapping, a participatory mixed-methods research approach, to identify ECIG use behaviors and device characteristics perceived to be associated with cigarette smoking cessation or reduction.

METHODS

Current ECIG users aged 18-64 were recruited from seven cities selected randomly from U.S. census tract regions. Participants were invited to complete concept mapping tasks: brainstorming, sorting and rating (n=72). During brainstorming, participants generated statements in response to a focus prompt ("A SPECIFIC WAY I HAVE USED electronic cigarettes to reduce my cigarette smoking or a SPECIFIC WAY electronic cigarettes help me reduce my cigarette smoking is…") and then sorted and rated the statements. Multidimensional scaling and hierarchical cluster analyses were used to generate a cluster map that was interpreted by the research team.

RESULTS

Eight thematic clusters were identified: Convenience, Perceived Health Effects, Ease of Use, Versatility and Variety, Advantages of ECIGs over Cigarettes, Cigarette Substitutability, Reducing Harms to Self and Others, and Social Benefits. Participants generated several statements that related to specific behavioral strategies used when using ECIGs for smoking reduction/complete switching behaviors such as making rapid transitions from smoking to ECIG use or using certain ECIG liquids or devices. Former smokers rated the Perceived Health Effects cluster and several behavioral strategy statements higher than current smokers.

CONCLUSIONS

These results help to identify ECIG use behaviors and characteristics perceived by ECIG users to aid in cigarette smoking cessation or reduction.

User identified positive outcome expectancies of electronic cigarette use: A concept mapping study

Electronic cigarette (ECIG) use is growing in popularity, but little is known about the perceived positive outcomes of ECIG use. This study used concept mapping (CM) to examine positive ECIG outcome expectancies. Sixty-three past 30-day ECIG users (38.1% female) between the ages of 18 and 64 (M = 37.8, SD = 13.3) completed a CM module. In an online program, participants provided statements that completed a prompt: "A specific positive, enjoyable, or exciting effect (i.e., physical or psychological) that I have experienced WHILE USING or IMMEDIATELY AFTER USING an electronic cigarette/electronic vaping device is. . . ." Participants (n = 35) sorted 123 statements into "piles" of similar content and rated (n = 43) each statement on a 7-point scale (1 = Definitely NOT a positive effect to 7 = Definitely a positive effect). A cluster map was created using data from the sorting task, and analysis indicated a 7 cluster model of positive ECIG use outcome expectancies: Therapeutic/Affect Regulation, High/Euphoria, Sensation Enjoyment, Perceived Health Effects, Benefits of Decreased Cigarette Use, Convenience, and Social Impacts. The Perceived Health Effects cluster was rated highest, although all mean ratings were greater than 4.69. Mean cluster ratings were compared, and females, younger adults, past 30-day cigarette smokers, users of more "advanced" ECIG devices, and nonlifetime (less than 100 lifetime cigarettes) participants rated certain clusters higher than comparison groups (ps < 0.05). ECIG users associate positive outcomes with ECIG use. ECIG outcome expectancies may affect product appeal and tobacco use behaviors and should be examined further to inform regulatory policies.

Reasons for using flavored liquids among electronic cigarette users: A concept mapping study

BACKGROUND

Electronic cigarettes (ECIGs) aerosolize liquids often containing flavorants for inhalation. Few studies have examined the role of flavors in ECIG use. This study's purpose was to examine reasons for flavored ECIG use using a mixed-method approach, concept mapping (CM).

METHODS

Forty-six past 30-day adult ECIG users recruited from vape forums/conferences completed three online CM tasks. Participants brainstormed responses to a prompt: "A specific reason I use flavored e-liquid in my electronic cigarette product is…". The final 107 brainstormed statements were sorted by participants into groups of similar content. Participants rated each statement on a 7-point scale (1-Definitely NOT a reason to 7-Definitely a reason) based on a prompt: "This is a specific reason why I used flavored e-liquid in my electronic cigarette product in the past month." A cluster map was generated from participants' sorting and ratings using CM statistical software. Cluster mean ratings were compared.

RESULTS

Analysis revealed five clusters of reasons for flavored ECIG use including Increased Satisfaction/Enjoyment, Better Feel/Taste than Cigarettes, Variety/Customization, Food Craving Suppression, and Social Impacts. Statements in the Increased Satisfaction/Enjoyment and Better Feel/Taste than Cigarettes clusters were rated significantly higher than statements from other clusters (ps<0.05). Some statements indicated flavors were perceived as masking agents for nicotine or other bad tastes associated with cigarette smoking making ECIG use more palatable.

CONCLUSIONS

Flavored ECIGs are used for many reasons. Some statements suggested flavors may increase the rewarding and possible addictive effects of ECIGs. These results support continued examination of the role of flavors and ECIG use behaviors.

Characteristics and Patterns of Black & Mild Use Among African American Smokers

INTRODUCTION

Increased consumption of little cigars and cigarillos (LCCs) among late adolescent and young adult African American smokers is an emerging public health concern. Despite a growing body of epidemiological evidence, there is scant research on systematic variations in LCC use among young adult African Americans. This study aimed to disaggregate African American Black & Mild (B&M) smokers and to identify subgroups of cigarillo smokers' behaviors and associated characteristics.

METHODS

Using telephone screening data for a NIH-funded clinical laboratory study of toxicant exposure associated with B&M use, latent class analysis (LCA) was used to classify 331 African American B&M smokers' based on daily use, average daily consumption, preference for flavors, preference for product design tips, and product modification behaviors.

RESULTS

Results showed five classes, three of which (Daily-Hypers, Daily-Flavored, and Heavy-Daily-Hypers) reflected daily use and average daily consumption rate ranging between 2.7 and 8.9 B&M cigarillos per day. Non-Daily-Hypers and Non-Daily-Flavored classes represented non-daily use patterns and averaged less than 1.0 B&M cigarillo per day. Both sets of classes defined by daily users and non-daily users included smokers who preferred flavored tobacco and who practiced product modification techniques involving hyping and blunting.

CONCLUSIONS

Latent class analysis is a useful method to detect subtle differences in B&M product preferences and smoking behaviors among African Americans. Study findings highlight the importance of developing tailored interventions that consider within group differences in order to reduce the prevalence of cigarillo smoking among those with the greatest burden.

IMPLICATIONS

The current study is the first to identify unique subgroups of African American B&M smokers based on cigarillo use behaviors and associated characteristics. Latent class analyses may prove useful for understanding other subgroups of tobacco users. Current findings concerning patterns of LCC use illustrate how future tobacco cessation and prevention interventions may be tailored for African American smokers.

Smoking and prostate cancer in a multi-ethnic cohort

BACKGROUND

Prostate cancer (PCa) and smoking-related morbidity disproportionately burdens African American (AA) men. Smoking is associated with high-grade PCa and incidence, but few studies have focused on AA men. This study aims to determine the effect of tobacco-use on odds of PCa and of high-grade PCa in a population of predominantly AA men.

METHODS

This is a cross-sectional study evaluating smoking and PCa status in men with incident PCa and screened healthy controls. Altogether, 1,085 men (527 cases and 558 controls), age ≥ 40 years were enrolled through outpatient urology clinics in two US cities from 2001 to 2012. Validated questionnaires were used to gather clinical and socioeconomic data.

RESULTS

The cases and controls were predominantly AA (79.9% and 71.3%, respectively, P = 0.01). AA men smoked more frequently (53.4% vs. 47.9%, P < 0.001) and quit less frequently than European American (EA) men (31.5% vs. 40.4%, P = 0.01). AA heavy smokers had increased odds of PCa diagnosis (OR 2.57, 95% CI 1.09, 6.10) and high-grade cancer (OR 1.89, 95% CI 1.03, 3.48) relative to never smokers and light smokers. Among AAs, heavy smokers had lower odds of NCCN low PCa recurrence risk stratification. AA former smokers had a trend for increased odds of high-grade cancer compared to never smokers. The associations between smokings, cancer diagnosis and cancer grade did not reach statistical significance in EA men.

CONCLUSION

We found ethnic differences in smoking behavior. Heavy smoking is associated with increased odds of PCa and of higher Gleason grade in AA men.

Investigating social ecological contributors to diabetes within Hispanics in an underserved U.S.-Mexico border community

Hispanics bear a disproportionate burden of diabetes in the United States, yet relations of structural, socio-cultural and behavioral factors linked to diabetes are not fully understood across all of their communities. The current study examines disparities and factors associated with diabetes in adult Hispanics of Mexican-descent (N = 648) participating in a population survey of an underserved rural U.S.-Mexico border community. The overall rate of diabetes prevalence rate in the sample, based on self-report and a glucose testing, was 21%; much higher than rates reported for U.S. adults overall, for all Hispanic adults, or for Mexican American adults specifically. Acculturation markers and social determinants of health indicators were only significantly related to diabetes in models not accounting for age. Older age, greater BMI (>30), greater waist-to-hip ratio as well as lower fruit and vegetable consumption were significantly related to increased likelihood of diabetes when all structural, cultural, behavioral, and biological factors were considered. Models with sets of behavioral factors and biological factors each significantly improved explanation of diabetes relative to prior social ecological theory-guided models. The findings show a critical need for diabetes prevention efforts in this community and suggest that health promotion efforts should particularly focus on increasing fruit and vegetable consumption.

Relationship between smokers' modes of entry into quitlines and treatment outcomes

OBJECTIVES

To assess the relationship between the mode of entry into a quitline service and subsequent tobacco use treatment outcomes.

METHODS

A retrospective study using logistic regression analysis of 11,040 Arizona Smokers' Helpline (ASHLine) clients was conducted to determine whether self- or medical referrals were related to 7- and 30-day point prevalence tobacco treatment outcomes at 7 months postquit.

RESULTS

Smokers referred to the ASHLine by a health care provider were more likely to quit smoking than were those who self-referred.

CONCLUSIONS

Mode of entry into a quitline service for smoking cessation is related to treatment outcomes. Reasons for this outcome are uncertain and require additional research.

Evaluation of prescriber responses to pharmacist recommendations communicated by fax in a medication therapy management program (MTMP)

BACKGROUND

As defined by the Medicare Prescription Drug, Improvement, and Modernization Act of 2003, medication therapy management programs (MTMPs) must be designed to decrease adverse drug events and improve patient outcomes by promoting appropriate medication use. WellPoint Inc. contracted with the pharmacist-run University of Arizona College of Pharmacy Medication Management Center (UA MMC) to provide a pilot telephone-based MTMP to approximately 5,000 high-risk beneficiaries from among its nearly 2 million Medicare prescription drug plan (PDP) beneficiaries. Eligibility for the program was determined by a minimum of 2 of 6 chronic diseases (dyslipidemia, cardiovascular disease, depression, diabetes mellitus, congestive heart failure, and chronic obstructive pulmonary disease; at least 1 of the latter 2 diseases must be present), at least 3 Part-D covered medications, and greater than $4,000 per year in predicted drug spending. In addition to these criteria, WellPoint Inc. used the Johns Hopkins adjusted clinical groups (ACG) predictive model to identify the high-risk beneficiaries to be enrolled in the program. Medication therapy reviews were conducted for these patients. If any medication-related problems (MRPs) were identified, the patient's prescribers were contacted via a fax communication with recommendation(s) to resolve these MRPs. The UA MMC fax interventions were categorized as cost saving, guideline adherence, or safety concerns.

OBJECTIVES

To (a) determine prescriber responses to pharmacist-initiated recommendations in an MTMP for the 3 intervention categories, (b) compare prescriber responses between intervention categories, and (c) compare prescriber response by prescriber type (primary care physician [PCP] vs. specialist) within each intervention category.

METHODS

A retrospective analysis of pharmacist-initiated interventions from August through December 2008 was performed using data collected from the UA MMC database. Data were collected on intervention category (cost saving, guideline adherence, or safety concerns), and responses of prescribers were recorded as either approval or decline (no response was considered decline). Prescriber specialty was identified from searching records of state medical boards. Logistic regression analyses with the robust variance option to adjust for correlation within prescribers were conducted to compare prescriber approval rates between and within intervention categories. Significance was assessed at alpha 0.05.

RESULTS

Of 4,967 Medicare Part D beneficiaries determined to be MTMP-eligible, 4,277 beneficiaries (86.1%) were available for assessment (400 declined, 186 disenrolled, and 104 were deceased). Pharmacists initiated 1,548 valid medication recommendations (i.e., recommendations were excluded for deceased patients, incorrect prescribers, and where prescriber specialty was not identified). These recommendations for 1,174 beneficiaries (27.5% of those available) were faxed to prescribers requesting approval. Mean (SD) age for beneficiaries having recommendations was 72.9 (9.4) years, and the majority (57.6%) was female. By category of recommendation, 58.3% (n=902) were guideline adherence, 33.3% (n=515) were cost saving, and 8.5% (n=131) were safety concerns. Prescriber approval rates were 47.2% overall (n =731/1,548), 41.4% (n=373/902) for guideline adherence, 58.3% (n=300/515) for cost savings, and 44.3% (n=58/131) for safety concerns; 817 recommendations were not approved by prescribers (n= 255 [16.5%] denials and 562 no response [36.3%]). Prescriber approval was significantly higher for cost-saving interventions compared with guideline adherence interventions (odds ratio [OR]=1.98, 95% CI=1.56-2.51, P< 0.001) and compared with safety interventions (OR=1.76, 95% CI=1.19, 2.59, P=0.004); there was no significant difference in the prescriber approval rates for the interventions for safety versus guideline adherence. The overall approval rate was higher for PCPs (49.8%, n=525/1,054) versus specialists (41.7%, n=206/494; OR=1.39, 95% CI=1.08-1.78, P=0.011) and for the category for guideline adherence interventions (44.0% for PCPs vs. 35.9% for specialists; OR =1.40, 95% CI=1.01-1.95, P=0.044), but not for the other 2 intervention categories.

CONCLUSIONS

Prescriber approval rates for pharmacist recommendations for drug therapy changes for MTMP beneficiaries were approximately 47% overall and higher for recommendations that involved cost savings compared with recommendations for safety concerns or guideline adherence. Compared with specialists, PCPs had higher approval rates for pharmacist recommendations overall and for the intervention category guideline adherence.
