1441-1444AbstractAs the prevalence rates of cigarette use have declined over the past decade, use of electronic cigarettes (e-cigarettes) continues to increase, and companies are heavily invested in manufacturing new e-cigarette products. Scientists are therefore studying e-cigarette use at a rapid rate, generally by conceptualizing e-cigarettes as similar to traditional cigarettes in their use and effects. Thinking of e-cigarettes as largely comparable with cigarettes, however, fails to capture the unique e-cigarette capabilities, user experiences, and effects on nicotine dependence and even health. Assuming that e-cigarette users puff on their devices as they do cigarettes to attain doses of nicotine comparable in magnitude and asking questions about e-cigarette use modeled after how smoking behavior has been usually assessed (eg, puff number, duration, number of cigarettes per day) may miss important differences. A greater appreciation of the distinct uniqueness of e-cigarettes, as compared with cigarettes, will help to accelerate innovative research on e-cigarettes and other electronic devices, leading to new theoretical models and behavioral measures. Implications: With research about electronic cigarettes (e-cigarettes) rapidly increasing, this commentary addresses the conceptualization of e-cigarettes as similar to traditional cigarettes. The more we attempt to understand and measure e-cigarettes as equivalent to cigarettes, the more likely research may err in conclusions about these unique devices. Our commentary notes how using unique conceptualizations and measures for e-cigarettes will help accelerate new research.A pilot randomized trial examining the feasibility and acceptability of a culturally tailored and adherence-enhancing intervention for Latino smokers in the U.S.

1AbstractLatino smokers in the United States (US) are known to experience smoking cessation treatment disparities due to their under-utilization of services, limited access to health care, and poor smoking cessation treatment outcomes. A limited number of studies have focused on developing and testing smoking cessation treatments for Latino smokers in the US. The objectives of this study were to conduct a feasibility pilot randomized trial testing three smoking cessation interventions for Latinos. Twenty-five adult Latino smokers were randomized to one of three groups: Culturally-Tailored Smoking Cessation plus Adherence Enhancement (CT+AE), Culturally-Tailored Smoking Cessation (CTSC), and a Health Education (HE) control group. All participants received three counseling sessions along with nicotine replacement therapy (NRT). Data relating to intervention acceptability and NRT adherence were collected. Self-reported 7-day point prevalence smoking was collected at 3 and 6 month follow-up and biochemically verified with expired carbon monoxide testing. Overall, the interventions demonstrated high levels of feasibility and acceptability. Days of nicotine patch use were found to be higher in the CT+AE group (mean (M) = 81.3;standard deviation (SD) = 3.32) than the CTSC (M = 68.6;SD = 13.66) and HE (M = 64;SD = 17.70) groups. At 3-month follow-up, approximately 50% of the CT+AE group were smoking abstinent, 25% of the CTSC group, and 44% of the HE group. At 6-month follow-up, 37.5% of the CT+AE group were abstinent, 25% of the CTSC group, and 44.4% of the HE group. This study is the first to target Latino smokers in the US with a culturally-tailored intervention that addresses treatment adherence. Results support the preliminary feasibility and acceptability of the CT+AE intervention.An African-specific haplotype in MRGPRX4 is associated with menthol cigarette smoking

2AbstractIn the U.S., more than 80% of African-American smokers use mentholated cigarettes, compared to less than 30% of Caucasian smokers. The reasons for these differences are not well understood. To determine if genetic variation contributes to mentholated cigarette smoking, we performed an exome-wide association analysis in a multiethnic population-based sample from Dallas, TX (N = 561). Findings were replicated in an independent cohort of African Americans from Washington, DC (N = 741). We identified a haplotype of MRGPRX4 (composed of rs7102322[G], encoding N245S, and rs61733596[G], T43T), that was associated with a 5-to-8 fold increase in the odds of menthol cigarette smoking. The variants are present solely in persons of African ancestry. Functional studies indicated that the variant G protein-coupled receptor encoded by MRGPRX4 displays reduced agonism in both arrestin-based and G protein-based assays, and alteration of agonism by menthol. These data indicate that genetic variation in MRGPRX4 contributes to inter-individual and inter-ethnic differences in the preference for mentholated cigarettes, and that the existence of genetic factors predisposing vulnerable populations to mentholated cigarette smoking can inform tobacco control and public health policies.Associations of risk factors of e-cigarette and cigarette use and susceptibility to use among baseline PATH study youth participants (2013–2014)

51-60AbstractIntroduction: Improved understanding of the distribution of traditional risk factors of cigarette smoking among youth who have ever used or are susceptible to e-cigarettes and cigarettes will inform future longitudinal studies examining transitions in use. Methods: Multiple logistic regression analysis was conducted using data from youth (ages 12–17 years) who had ever heard of e-cigarettes at baseline of the PATH Study (n = 12,460) to compare the distribution of risk factors for cigarette smoking among seven mutually exclusive groups based on ever cigarette/e-cigarette use and susceptibility status. Results: Compared to committed never users, youth susceptible to e-cigarettes, cigarettes, or both had increasing odds of risk factors for cigarette smoking, with those susceptible to both products at highest risk, followed by cigarettes and e-cigarettes. Compared to e-cigarette only users, dual users had higher odds of nearly all risk factors (aOR range = 1.6–6.8) and cigarette only smokers had higher odds of other (non-e-cigarette) tobacco use (aOR range = 1.5–2.3), marijuana use (aOR = 1.9, 95%CI = 1.4–2.5), a high GAIN substance use score (aOR = 1.9, 95%CI = 1.1–3.4), low academic achievement (aOR range = 1.6–3.4), and exposure to smoking (aOR range = 1.8–2.1). No differences were observed for externalizing factors (depression, anxiety, etc.), sensation seeking, or household use of non-cigarette tobacco. Conclusions: Among ever cigarette and e-cigarette users, dual users had higher odds of reporting traditional risk factors for smoking, followed by single product cigarette smokers and e-cigarette users. Understanding how e-cigarette and cigarette users differ may inform youth tobacco use prevention efforts and advise future studies assessing probability of progression of cigarette and e-cigarette use.E-cigarette Use and Myocardial Infarction : Association Versus Causal Inference

280-289AbstractThe role of tobacco marketing in tobacco use, particularly among the vulnerable ethnic and socioeconomic sub-populations is a regulatory priority of the U.S. Food and Drug Administration. There currently exist both ethnic and socioeconomic disparities in the use of tobacco products. Monitoring such inequalities in exposure to tobacco marketing is essential to inform tobacco regulatory policy that may reduce known tobacco-related health disparities. We use data from the Population Assessment of Tobacco and Health (PATH) Wave 1 youth survey to examine (1) recalled exposure to and liking of tobacco marketing for cigarettes, non-large cigars, and e-cigarettes, (2) self-reported exposure to specific tobacco marketing tactics, namely coupons, sweepstakes, and free samples, and (3) self-reported impact of tobacco marketing and promotions on product use. Findings indicate that African Americans and those of lower SES were more likely to recall having seen cigarette and non-large cigar ads. Reported exposure to coupons, sweepstakes and free samples also varied ethnically and socioeconomically. African Americans and those of lower SES were more likely than other respondents to report that marketing and promotions as played a role in their tobacco product use. Better understanding of communication inequalities and their influence on product use is needed to inform tobacco regulatory action that may reduce tobacco company efforts to target vulnerable groups. Tobacco education communication campaigns focusing on disproportionately affected groups could help counter the effects of targeted industry marketing.Is e-cigarette use associated with coronary heart disease and myocardial infarction?

10AbstractBackground: This study analyzed the National Health Interview Surveys (NHIS) of 2016 (n = 33,028) and 2017 (n = 26,742) to examine whether e-cigarette use is consistently associated with myocardial infarction (MI) and coronary heart disease (CHD). Methods: Surveys were examined separately and pooled. Logistic regression analysis was used, with demographics, e-cigarette use, smoking and risk factors for CHD (hypertension, hypercholesterolemia, and diabetes) being independent variables. Former smokers were subclassified according to quit duration (⩽ 6 and > 6 years). Results: For MI, an association was observed with some days e-cigarette (but not daily) use in the 2017 survey (OR: 2.11, 95% CI: 1.14–3.88, p = 0.017). No statistically significant association was observed in the pooled analysis (daily e-cigarette use: OR: 1.35, 95% CI: 0.80–2.27, p = 0.267). For CHD, an association was observed with daily e-cigarette use in the 2016 survey (OR: 1.89, 95% CI: 1.01–3.53, p = 0.047). From the pooled analysis, no association was found between any pattern of e-cigarette use and CHD. In single-year and pooled analysis, both MI and CHD were strongly associated with all patterns of smoking, hypertension, hypercholesterolemia, diabetes, and age. Conclusions: The pooled analysis of the 2016 and 2017 NHIS showed no association between e-cigarette use and MI or CHD. The associations between established risk factors, including smoking, and both conditions were remarkably consistent. The inconsistent associations observed in single-year surveys and the cross-sectional design of the NHIS cannot substantiate any link between e-cigarette use and an elevated risk for MI or CHD. Longitudinal studies are needed to explore the effects of e-cigarette use on cardiovascular disease.Latent Classes of Nicotine Beliefs Correlate with Perceived Susceptibility and Severity of Nicotine and Tobacco Products in US Young Adults

S91-S100AbstractBackground: Pervasive misperceptions about nicotine may influence uptake of quit smoking aids and the impact of policies addressing nicotine as a tobacco product constituent. Methods: Latent class analyses were conducted using four items on nicotine beliefs asked of 4037 adults aged 18-40 in wave 9 (February-March 2016) of the Truth Initiative Young Adult Cohort Study. Confirmatory factor analyses identified three factors from 12 items: nicotine susceptibility (NSUS), nicotine severity (NSEV), and tobacco severity (TSEV). Analyses assessed correlations between latent classes, sociodemographics, and nicotine/tobacco factor scores. Results: A four-class model of nicotine beliefs was the best fit, with the largest class believing that nicotine plays a major part in smoking risks (class 1, n = 2070; 52%). Class 2 shared that belief but also responded "Don't know" to addiction questions (class 2, n = 382; 11%). Fewer belonged in class 3, who reported that nicotine plays a small part in health risks (n = 1277; 30%), and class 4, who perceived nicotine as not cancer causing (n = 308; 7%). Latent class membership was correlated with sociodemographics, peer smoking, and past 30-day tobacco use. Classes 1 and 2 had similar NSUS scores and classes 3 and 4 had similar NSEV and TSEV scores. Discussion: Differences in the perceptions of nicotine and tobacco-related harms can be partially explained by clustering of underlying nicotine beliefs. These classes of beliefs are correlated with sociodemographic predictors of smoking. These findings may help to identify specific beliefs or groups to be targeted by public education efforts on nicotine. Implications: The current study supports that underlying nicotine beliefs are associated with perceived harms of specific nicotine and tobacco products (relative to cigarettes), with greater false beliefs about nicotine correlated with greater perceived susceptibility to nicotine addiction. Two important inferences emerge from this study: first, that education to address nicotine beliefs may also reframe perceptions of the harms of nicotine and tobacco products; and second, that this type of education may differentially impact perceptions of the harms of nicotine products (e.g., nicotine replacement therapy and e-cigarettes) and tobacco products (e.g., cigars, smokeless, and hookah).Longitudinal tobacco use transitions among adolescents and young adults : 2014-2016

458-468AbstractIntroduction: Among youth, the frequency and prevalence of using more than one tobacco (small cigar, cigarette, and hookah) or nicotine-containing product (e-cigarettes-ENDS) are changing. These shifts pose challenges for regulation, intervention, and prevention campaigns because of scant longitudinal data on the stability of use patterns in this changing product landscape. Methods: A nationally representative longitudinal survey of 15- to 21-year olds (n = 15,275) was used to describe transitions between never use, noncurrent use, and past 30-day use of combustible tobacco, e-cigarettes (ENDS), and dual use of both kinds of products. A multistate model was fit to observations collected every 6 months across 2.5 years to estimate the probability of transitions between states (TPs), the average time in state (sojourn time), and the effect of age on transitions. Results: Current state strongly predicted future state over time intervals of 1 year or less, but only weakly predicted future state at longer intervals: TP to noncurrent use was higher for ENDS-only than combustible-only users over a 6-month interval but was similar for both groups over a 2-year interval. Sojourn time was significantly longer for combustible-only (0.52 years) and dual use (0.55 years) than ENDS-only use (0.27 years); older youth were more likely than younger youth to stay combustible tobacco users or noncurrent users. Conclusions: The dynamics of transitions between combustible tobacco products and ENDS in a population of youth and young adults suggest that policy and prevention efforts must consider the frequent changes and instability over a 1-year or less time period in use patterns among young people. Implications: The study addresses an urgent need in public health for timely information on how youth and young adults use tobacco and nicotine products. We found that youth, particularly adolescents, moved frequently between using ENDS and combustible tobacco products either alone or together. Importantly, the utility of current-use states for predicting future use states declined for time horizons longer than 1 year. Our results demonstrate a need for caution in interpreting product transitions. Longitudinal data with frequent observations and coverage of a wide range of possible product types is required to fully characterize usage patterns in youth.Marketing Influences on Perceptions of Reduced Nicotine Content Cigarettes

S117-S124AbstractINTRODUCTION: The Food and Drug Administration announced intent to reduce the nicotine content in cigarettes. There is limited evidence on how reduced nicotine content cigarette (RNC) marketing affects product beliefs and use, and research on this is needed to inform regulations.METHODS: In an online experiment, 426 young adult cigarette smokers (aged 18-30 years) were randomized in a 2 (implicit: red package vs. blue package) × 2 (explicit: corrective message vs. no corrective message) design to view an advertisement for previously commercially available RNCs. Outcomes were advertisement content recall, product beliefs, and use intentions. Participants' responses to open-ended assessment of their beliefs about the stimuli were coded to identify prevailing themes.RESULTS: Red packaging and corrective messaging were independently associated with greater advertisement content recall (p = .01 and p = .04, respectively). There were no significant main or interaction effects on product beliefs or use intentions. Controlling for condition, advertisement content recall was significantly associated with less favorable product beliefs (p < .001) and favorable product beliefs were associated with intent to use the product (p < .001). Open-ended responses converged on the finding that respondents were interested in RNCs, but expressed skepticism about effectiveness and value.CONCLUSIONS: Brief exposure to an RNC advertisement with red packaging and corrective messaging were each independently associated with greater advertisement content recall. The results indicate: (1) interest and confusion among young adult smokers regarding RNCs, (2) beliefs about RNCs are influenced by marketing, and (3) beliefs are associated with intention to use RNCs.IMPLICATIONS: Findings from this study demonstrate the importance of advertising effects on beliefs about RNC products and support the need to regulate advertising and labeling alongside product regulation. More detailed study of advertisement features that affect consumers' beliefs about RNCs and how they impact their processing of explicit messaging about product risks will be important to guide regulatory decision-making.Nicotine maintenance for smokers in methadone treatment : a new direction

269-276AbstractPatients of methadone maintenance treatment (MMT) exhibit an exceedingly high prevalence of tobacco use and disproportionately suffer from tobacco-related illnesses and mortality. A number of studies have sought to target MMT smokers with cessation interventions utilizing a variety of behavioral and pharmacological treatments. Such efforts have struggled to attain even modest rates of cessation at follow-up, suggesting a need for novel approaches. In an effort to accelerate this area of research, the current article proposes an alternative paradigm for MMT smokers: Nicotine Maintenance. The proposed model emphasizes five domains aimed at advancing the contextual fit between smoking cessation treatment and MMT: (1) A harm reduction and maintenance orientation; (2) a reconsideration of abstinence-oriented frameworks and techniques; (3) a longer-term perspective; (4) greater integration with the MMT treatment milieu; and (5) approaches that address the unique needs of MMT patients including shame, stigma, and the enhancement of treatment autonomy.Patterns of E-Cigarette Use among Youth and Young Adults : Review of the Impact of E-Cigarettes on Cigarette Smoking

1320-1330AbstractThere is concern that e-cigarette use among youth and young adults (YAs) may lead to future cigarette or other combustible tobacco product use. A synthesis of the literature on this topic is needed because existing longitudinal studies are limited in number and not consistent in their conclusions. We conducted a search in PubMed through December 31, 2017 for peer-reviewed studies related to e-cigarette patterns of use. Of 588 relevant studies, 26 had a youth or YA sample, were longitudinal in design, and assessed e-cigarette use at baseline and cigarette smoking at follow-up. Most studies followed a sample over time and compared cigarette smoking at follow-up between baseline e-cigarette users and nonusers. Other studies examined the difference at follow-up in cigarette smoking status among smokers according to e-cigarette use at baseline. Results suggest that, among never smokers, e-cigarette use is associated with the future (6 months to 2.5 years) cigarette trial; however, firm conclusions cannot be drawn because of limitations including small sample size, measurement of experimental use (ie, ever use, past 30-day use) rather than established use, and inadequate controls for potentially confounding variables. Conclusions also cannot be drawn from studies examining the impact of e-cigarette use among smokers due to the limited number of studies and additional limitations. A comprehensive understanding of this literature is needed to inform policy makers and consumers for evidence-based decision-making and to guide future research on e-cigarette use among youth and young adults. Implications: The present article provides a review of the impact of e-cigarette use on subsequent cigarette smoking among youth and YAs. Studies presented here suggest that e-cigarette use among nonsmokers is associated with subsequent cigarette smoking, but study designs are subject to numerous limitations. Future research should focus on addressing the characteristics that put youth and YAs at the risk of using either product and how appeal and accessibility of these products are related to product use in order to inform future policy-making.Prevalence and correlates of nicotine and nicotine product perceptions in U.S. young adults, 2016

98AbstractIntroduction: Nicotine is not a human carcinogen and combustion compounds in tobacco smoke, rather than nicotine, cause tobacco-related cardiovascular disease. Few recent studies examine the public's beliefs about nicotine in relation to smoking. Methods: Participants aged 18-40 (n = 4,091) in Wave 10 (Fall 2016) of the Truth Initiative Young Adult Cohort Study responded to nineteen items on nicotine and nicotine product perceptions, including addictiveness and health harms of nicotine patch/gum and e-cigarettes compared to cigarettes. Analyses conducted in 2018 examined prevalence of perceptions and sociodemographic and tobacco use correlates of selected perceptions. Results: The majority of young adults reported that nicotine was responsible for a “relatively” or “very large” part of the health risks (66%) and cancer (60%) caused by smoking. More than half of young adults (55%) believed that nicotine is a cause of cancer. Between 23% and 43% of young adults responded “don't know” to items on nicotine. Females, blacks, Hispanics, and those with less than some college education were more likely to report true or “don't know” vs. false to “nicotine is a cause of cancer” and had higher odds of believing that nicotine was responsible for a “relatively” or “very large” part of the health risks of smoking and cancer caused by smoking. Past 30-day tobacco users had lower odds of reporting these beliefs. Conclusions: Misperceptions of nicotine are widespread in young adults. Public education is needed to maximize the public health impact of FDA's required nicotine warning label and proposed nicotine reduction policies.Prevalence and Correlates of Snuff Use, and its Association with Tuberculosis, among Women Living with HIV in South Africa

1087-1092AbstractIntroduction: A higher proportion of people living with HIV (PLWH) smoke compared to the general population, but little information exists about the prevalence and correlates of smokeless tobacco use among PLWH. In South Africa, dry powdered tobacco is inhaled nasally as snuff. Methods: A cross-sectional survey among PLWH attending three HIV clinics was conducted. Snuff use was assessed via self-report and urine cotinine. Results: Given the low (3%) prevalence of snuff use among men, analysis was restricted to n = 606 nonsmoking women living with HIV. Half (n = 298, 49%) were snuff users, the majority of whom (n = 244, 84%) had a positive urine cotinine test. In adjusted analysis, snuff use was negatively associated with higher education (relative risk [RR] 0.55; 95% confidence interval [CI]: 0.39, 0.77) and mobile phone ownership (RR 0.83; 95% CI: 0.71, 0.98), and positively associated with ever having tuberculosis (TB) (RR 1.22; 95% CI: 1.03, 1.45). In adjusted analysis, with current TB as the outcome, snuff use was marginally statistically significantly associated with a twofold increase in odds of a current TB diagnosis (odds ratio [OR] 1.99; 95% CI: 0.98, 4.15). Discussion: A high proportion of nonsmoking South African women living with HIV use snuff, which was a risk factor for TB. Additional research is needed to understand the relationship between snuff, TB, and other potential health risks. Implications: PLWH have a higher prevalence of smoking than their seronegative peers, but there is a paucity of research on smokeless tobacco use in this population, especially in low-resource settings. TB is the leading cause of death among PLWH, and with improvements to HIV treatment and care, PLWH are at greater risk of tobacco-related diseases. We report an extremely high prevalence of snuff use among women living with HIV in South Africa. Further, in this population snuff use is positively associated with ever having a TB diagnosis, as well as currently having TB.Preventing Smoking Progression in Young Adults : the Concept of Prevescalation

377-384AbstractAs adolescents cross the threshold to young adulthood, they encounter more opportunities to engage in or accelerate previously discouraged or prohibited behaviors. Young adults, therefore, are more apt to initiate cigarette smoking and, more importantly, to accelerate their use if they tried and experimented as an adolescent. Preventing the escalation and entrenchment of smoking in the young adult years is critically important to reducing tobacco’s long-term health toll. However, traditional interventions for youth have focused on preventing smoking initiation, and interventions for adults have focused on smoking cessation; both have failed to address the needs of young adults. We introduce the concept of “prevescalation” to capture the need and opportunity to prevent the escalation of risk behaviors that typically occur during young adulthood, with a focus on the example of cigarette smoking. Prevescalation negates the notion that prevention has failed if tobacco experimentation occurs during adolescence and focuses on understanding and interrupting transitions between experimentation with tobacco products and established tobacco use that largely occur during young adulthood. However, since risk behaviors often co-occur in young people, the core concept of prevescalation may apply to other behaviors that co-occur and become harder to change in later adulthood. We present a new framework for conceptualizing, developing, and evaluating interventions that better fit the unique behavioral, psychosocial, and socio-environmental characteristics of the young adult years. We discuss the need to target this transitional phase, what we know about behavioral pathways and predictors of cigarette smoking, potential intervention considerations, and research challenges.Re : Disregarding the impact of nicotine on the developing brain when evaluating costs and benefits of noncombustible nicotine products

158-159AbstractThis Letter to the Editor is in response to a letter from Ms. Flannery, titled, “Disregarding the impact of nicotine on the developing brain when evaluating costs and benefits of noncombustible nicotine products”. In our response, we address some concerns raised by Ms. Flannery, and reiterate our position in our original article. In particular, we underline the importance of a rational public health calculus that weighs beneficial and harmful consequences of policies related to noncombustible nicotine product (NNP) use. We further emphasize the need to correct misperceptions about relative risk of different products to encourage smokers to switch to NNPs. Lastly, we are explicit about our assertion that no use of any nicotine-containing products is the only way to avoid harm at any age, but that we must view this issue pragmatically for the benefit of public health.Study protocol for a telephone-based smoking cessation randomized controlled trial in the lung cancer screening setting : The lung screening, tobacco, and health trial

Providing tobacco use treatment to high risk cigarette smokers in the LCS setting may result in health benefits beyond the impact of LCS. As one of the nine trials in the National Cancer Institute's Smoking Cessation at Lung Examination (SCALE) collaboration, the goal of the Lung Screening, Tobacco, and Health (LSTH) trial is to develop a scalable and cost-effective cessation intervention for subsequent implementation by LCS programs. Guided by the RE-AIM Framework, the LSTH trial is a two-arm RCT (N = 1330) enrolling English- and Spanish-speaking smokers registered for LCS at one of seven collaborating sites. Participants are randomly assigned to Usual Care (UC; three proactive telephone counseling sessions/two weeks of nicotine patches) vs. Intensive Telephone Counseling (ITC; eight proactive sessions/eight weeks of nicotine patches, plus discussion of the LCS results to increase motivation to quit). Telephone counseling is provided by tobacco treatment specialists. To increase continuity of care, referring physicians are notified of participant enrollment and smoking status following the intervention. Outcomes include: 1) self-reported 7-day, 30-day, and sustained abstinence, and biochemically-verified at 3-, 6-, and 12-months post-randomization, 2) reach and engagement of the interventions, and 3) cost-effectiveness of the interventions. The Cancer Intervention and Surveillance Modeling Network (CISNET) will model long-term impacts of six SCALE trials on the cost per life year saved, quality-adjusted life years saved, lung cancer mortality reduction, and population mortality. Clinical trials registration: The trial is registered at clinical trials.gov: NCT03200236.The Effects of Varying Electronic Cigarette Warning Label Design Features On Attention, Recall, and Product Perceptions Among Young Adults

317-324AbstractThis study was a 3 (Brand: Blu, MarkTen, Vuse) by 3 (Warning Size: 20%, 30%, or 50% of advertisement surface) by 2 (Warning Background: White, Red) experimental investigation of the effects of electronic cigarette (e-cigarette) warning label design features. Young adults aged 18–30 years (n = 544) were recruited online, completed demographic and tobacco use history measures, and randomized to view e-cigarette advertisements with warning labels that varied by the experimental conditions. Participants completed a task assessing self-reported visual attention to advertisements with a-priori regions of interest defined around warning labels. Warning message recall and perceived addictiveness of e-cigarettes were assessed post-exposure. Approximately half of participants reported attending to warning labels and reported attention was greater for warnings on red versus white backgrounds. Recall of the warning message content was also greater among those reporting attention to the warning label. Overall, those who viewed warnings on red backgrounds reported lower perceived addictiveness than those who viewed warnings on white backgrounds, and e-cigarette users reported lower perceived addictiveness than non-users. Among e-cigarette users, viewing warnings on white backgrounds produced perceptions more similar to non-users. Greater recall was significantly correlated with greater perceived addictiveness. This study provides some of the first evidence that e-cigarette warning label design features including size and coloring affect self-reported attention and content recall.Transitions in electronic cigarette use among adults in the Population Assessment of Tobacco and Health (PATH) Study, Waves 1 and 2 (2013-2015)

50-59AbstractIntroduction This study assessed patterns of e-cigarette and cigarette use from Wave 1 to Wave 2 among adult e-cigarette users at Wave 1 of the Population Assessment of Tobacco and Health (PATH) Study. Methods We examined changes in e-cigarette use frequency at Wave 2 among adult e-cigarette users at Wave 1 (unweighted n=2835). Adjusted prevalence ratios (aPR) were calculated using a predicted marginal probability approach to assess correlates of e-cigarette discontinuance and smoking abstinence at Wave 2. Results Half (48.8%) of adult e-cigarette users at Wave 1 discontinued their use of e-cigarettes at Wave 2. Among dual users of e-cigarettes and cigarettes at Wave 1, 44.3% maintained dual use, 43.5% discontinued e-cigarette use and maintained cigarette smoking and 12.1% discontinued cigarette use at Wave 2, either by abstaining from cigarette smoking only (5.1%) or discontinuing both products (7.0%). Among dual users at Wave 1, daily e-cigarette users were more likely than non-daily users to report smoking abstinence at Wave 2 (aPR=1.40, 95% CI 1.02 to 1.91). Using a customisable device (rather than a non-customisable one) was not significantly related to smoking abstinence at Wave 2 (aPR=1.14, 95% CI 0.81 to 1.60). Conclusions This study suggests that e-cigarette use patterns are highly variable over a 1-year period. This analysis provides the first nationally representative estimates of transitions among US adult e-cigarette users. Future research, including additional waves of the PATH Study, can provide further insight into long-term patterns of e-cigarette use critical to understanding the net population health impact of e-cigarettes in USA.Adult interest in using a hypothetical modified risk tobacco product : findings from wave 1 of the Population Assessment of Tobacco and Health Study (2013–14)

113-124AbstractBackground and aims: The US Family Smoking Prevention and Tobacco Control Act provides a pathway for manufacturers to market a modified risk tobacco product (MRTP). This study examines socio-demographic and tobacco use correlates of interest in a hypothetical MRTP in a nationally representative sample of US adults. Design: Cross sectional wave 1 data from the 2013–14 Population Assessment of Tobacco and Health (PATH) Study. Setting: Household Audio-Computer Assisted Self-Interviews of US adults conducted in 2013–14. Participants: A total of 32 320 civilian, non-institutionalized adults in the United States. Measurements: Interest in using a hypothetical MRTP (‘If a tobacco product made a claim that it was less harmful to health than other tobacco products, how likely would you be to use that product?’), socio-demographics, tobacco use history and mental health and substance use problems. All estimates were weighted. Findings: Overall, 16.7% [95% confidence interval (CI) = 16.28, 17.18] of US adults reported interest in a hypothetical MRTP. Tobacco use was associated significantly with interest in a hypothetical MRTP, with interest most common among current established smokers (54.4%; 95% CI = 53.31, 55.39) and least common among never tobacco users (3.0%; 95% CI = 2.49, 3.55). Interest in a hypothetical MRTP was associated with experimental e-cigarette use among current experimental, current established and former smokers. Among non-smokers, race, age, education and substance use were associated with interest in using a hypothetical MRTP. Conclusions: Among adults in the United States, interest in using a hypothetical modified risk tobacco product is low overall, and highest among current experimental and established smokers. A small percentage of non-smokers are interested in using a hypothetical hypothetical modified risk tobacco product.Communicating differences in tobacco product risks : Timing is of the essence

8AbstractImportance: Use of electronic cigarettes (e-cigarettes) is increasing. Measures of exposure to known tobacco-related toxicants among e-cigarette users will inform potential health risks to individual product users. Objectives: To estimate concentrations of tobacco-related toxicants among e-cigarette users and compare these biomarker concentrations with those observed in combustible cigarette users, dual users, and never tobacco users. Design, Setting, and Participants: A population-based, longitudinal cohort study was conducted in the United States in 2013-2014. Cross-sectional analysis was performed between November 4, 2016, and October 5, 2017, of biomarkers of exposure to tobacco-related toxicants collected by the Population Assessment of Tobacco and Health Study. Participants included adults who provided a urine sample and data on tobacco use (N = 5105). Exposures: The primary exposure was tobacco use, including current exclusive e-cigarette users (n = 247), current exclusive cigarette smokers (n = 2411), and users of both products (dual users) (n = 792) compared with never tobacco users (n = 1655). Main Outcomes and Measures: Geometric mean concentrations of 50 individual biomarkers from 5 major classes of tobacco product constituents were measured: nicotine, tobacco-specific nitrosamines (TSNAs), metals, polycyclic aromatic hydrocarbons (PAHs), and volatile organic compounds (VOCs). Results: Of the 5105 participants, most were aged 35 to 54 years (weighted percentage, 38%; 95% CI, 35%-40%), women (60%; 95% CI, 59%-62%), and non-Hispanic white (61%; 95% CI, 58%-64%). Compared with exclusive e-cigarette users, never users had 19% to 81% significantly lower concentrations of biomarkers of exposure to nicotine, TSNAs, some metals (eg, cadmium and lead), and some VOCs (including acrylonitrile). Exclusive e-cigarette users showed 10% to 98% significantly lower concentrations of biomarkers of exposure, including TSNAs, PAHs, most VOCs, and nicotine, compared with exclusive cigarette smokers; concentrations were comparable for metals and 3 VOCs. Exclusive cigarette users showed 10% to 36% lower concentrations of several biomarkers than dual users. Frequency of cigarette use among dual users was positively correlated with nicotine and toxicant exposure. Conclusions and Relevance: Exclusive use of e-cigarettes appears to result in measurable exposure to known tobacco-related toxicants, generally at lower levels than cigarette smoking. Toxicant exposure is greatest among dual users, and frequency of combustible cigarette use is positively correlated with tobacco toxicant concentration. These findings provide evidence that using combusted tobacco cigarettes alone or in combination with e-cigarettes is associated with higher concentrations of potentially harmful tobacco constituents in comparison with using e-cigarettes alone.Correlates of transitions in tobacco product use by u.S. adult tobacco users between 2013–2014 and 2014–2015 : Findings from the path study wave 1 and wave 2

11AbstractMore than half of adult tobacco users in the United States (U.S.) transitioned in tobacco product use between 2013–2014 and 2014–2015. We examine how characteristics of adult tobacco users in the U.S. relate to transitions in tobacco product use. Population Assessment of Tobacco and Health (PATH) Study data were analyzed from 12,862 adult current tobacco users who participated in Wave 1 (W1, 2013–2014) and Wave 2 (W2, 2014–2015). Three types of transitions were examined—(1) adding tobacco product(s); (2) switching to non-cigarette tobacco product(s); and (3) discontinuing all tobacco use—among those currently using: (1) any tobacco product; (2) cigarettes only (i.e., exclusive cigarette); and (3) cigarettes plus another tobacco product(s) (i.e., poly-cigarette). Multinomial logistic regression analyses determined relative risk of type of transition versus no transition as a function of demographic and tobacco use characteristics. Transitions in tobacco product use among adult tobacco users were common overall, but varied among different demographic groups, including by age, sex, sexual orientation, race/ethnicity, educational attainment, and poverty level. Further, cigarette smokers with higher dependence scores were more likely to add product(s) and less likely to discontinue tobacco use compared to those with low dependence scores. That high nicotine dependence is a barrier to discontinuing tobacco use adds evidence to support policy to lower nicotine content of cigarettes and to evaluate new products for their potential to reduce cigarette use.E-Cigarette Science and Its Relevance for Regulatory Actions and Policy

1069-1075AbstractIntroduction: Despite smoker interest in e-cigarettes as a harm reduction or cessation aid, many smokers prematurely discontinue vaping after trying a product. This study explored the role of early subjective sensory experiences in vaping persistence and desistance. Methods: African American menthol cigarette smokers aged ≥18 years (N = 15; M = 54.1 years; SD = 8.2), motivated to quit smoking, and interested in trying e-cigarettes were recruited in Washington, DC. Participants were followed for 3 weeks and provided menthol cigalike e-cigarettes after Week 1. Participants completed three interviews about their vaping experiences. Thematic analysis of responses was designed to understand the sensory aspects of vaping. Results: During the first 2 weeks of vaping, four participants reported a positive vaping experience while 11 reported decreased satisfaction. Salient sensory attributes of dissatisfaction included poor taste, insufficient throat hit, difficulty pulling, and a lack of “whole body” satisfaction compared to their preferred cigarette brand. Conclusions: The sensory experiences with a specific cigalike e-cigarette were related to vaping persistence and desistence. Although this was a small volunteer sample of African American menthol smokers motivated to quit smoking, 27% (N = 4) of participants with a positive vaping experience continued using the product, while 73% (N = 11) of participants' vaping experience was unsatisfactory across several experiential categories. In future research of e-cigarettes' efficacy as a smoking cessation or reduction aid, both device characteristics and smokers' expectations for these devices should be considered, so vapers do not expect the same taste sensations, throat sensations, and “whole body” satisfaction as they experienced with their menthol cigarettes. Implications: The subjective sensory experiences associated with initial e-cigarette product use are associated with use patterns. Subjective sensory experiences may also help understand the differences in the appeal, satisfaction, and harm-reduction potential of the rapidly evolving diverse types of products emerging in the marketplace. How products meet the sensory needs of smokers wanting to switch or quit smoking may influence adherence and success rates.
