RESUMO
PURPOSE: To explore how boxed warning (BW) information fits within the context of prescribers' overall treatment decision-making and communication with patients. METHODS: In-depth interviews (N = 52) were conducted with primary care providers and specialists. Participants were presented with one of two prescribing scenarios: (1) estrogen vaginal inserts to treat vulvovaginal atrophy (VVA) associated with menopause; or (2) direct-acting antivirals (DAA) to treat chronic hepatitis C virus infection (HCV). The semi-structured interviews explored participants' treatment decision-making within the scenario, reactions to current prescribing information for a product within the FDA-approved drug class, as well as their perceptions of BWs generally. RESULTS: Across scenarios, providers described that the BW is only one of several factors that influence treatment decision-making. In the VVA scenario, symptom severity, family history, and experience with nonprescription drugs were raised as common factors that influence prescribing considerations; compared to comorbid infections, viral load, and HCV genotype in the HCV scenario. Perceptions of the DAA BW were generally positive or neutral, as many participants found the information important and appropriate. The VVA BW was viewed less favorably, with many participants stating the BW overstates the risk for this drug. CONCLUSIONS: Findings suggest that BWs are one of several factors that influence providers' treatment decisions, and BW influence largely depends on context. Providers across scenarios expressed notable differences in their perceptions of the risk information provided in the presented BWs; however, across scenarios participants expressed consideration of how patients may perceive the BW.

INTRODUCTION: Cigarette smoking has declined, while electronic nicotine delivery system (ENDS) use has increased in the United States. Understanding the role of ENDS in adult smoking quit attempts and cessation is important for estimating their population health impact. AIMS AND METHODS: We used data from 2018 to 2019 tobacco use supplement to the current population survey to examine demographic characteristics and ENDS use patterns among adult ENDS users who reported quitting smoking in the past year by trying to switch to ENDS ("switchers") and smokers who did or did not make a quit attempt in the past year. χ2 tests of proportions and t-tests were used to compare characteristics between groups. RESULTS: In 2018-2019, about three-quarters of switchers reported daily use of ENDS compared to only one-third of dual users with a recent quit attempt by trying to switch to ENDS. Compared to dual users who made a quit attempt by trying to switch to ENDS, switchers were more likely to use menthol/mint-flavored ENDS exclusively (5.6% vs. 13.1%; pâ =â .004) but less likely to use tobacco-flavored ENDS exclusively (21.2% vs. 13.7%; pâ =â .01). CONCLUSIONS: ENDS users who quit smoking in the past year and reported trying to quit by switching to ENDS were more likely to use menthol/mint flavors exclusively and use ENDS daily compared to dual users who made a quit attempt by trying to switch to ENDS. Longer-term prospective data may better clarify the role of ENDS in smoking quit attempts and cessation. IMPLICATIONS: This study provides information on patterns of ENDS use in former smokers and current smokers who tried to quit smoking by switching to ENDS in a national sample of U.S. adults. These results can inform policy actions concerning ENDS products.

OBJECTIVE: Examine patterns of dual use of cigarettes and smokeless tobacco and complete switching over time among adult current cigarette smokers using data from the Population Assessment of Tobacco and Health Study Wave 3 (2015-2016), Wave 4 (2016-2018) and Wave 5 (2018-2019). METHODS: We examined four tobacco use states among 6834 exclusive smokers and 372 dual users at Wave 3 with two waves of follow-up data: exclusive cigarette use, exclusive smokeless tobacco use, dual use and use of neither product. RESULTS: Among exclusive smokers at Wave 3, only 1.6% (95% CI: 1.3% to 2.1%) transitioned to dual use at Wave 4, and 0.1% (95% CI: 0.07% to 0.2%) switched to exclusive smokeless tobacco use. Among exclusive smokers who switched to dual use, 53.1% (95% CI: 40.9% to 64.9%) returned to exclusive cigarette smoking, 34.3% (95% CI: 23.8% to 46.6%) maintained dual use and 12.6% (95% CI: 7.0% to 21.7%) did not smoke cigarettes after an additional wave of follow-up. Dual users at Wave 3 were likely to maintain their dual use status at Wave 4, 51.2% (95% CI: 46.1% to 56.3%) and Wave 5, 47.9% (95% CI: 40.1% to 55.8%). CONCLUSIONS: Very few cigarette smokers transition to smokeless tobacco use, and among those who do, dual use is more common than exclusive smokeless tobacco use. Further, the majority of exclusive cigarette smokers who transition to dual use at Wave 4 continue smoking cigarettes at Wave 5, either as dual users or as exclusive smokers.

INTRODUCTION: 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.

Electronic cigarettes (e-cigarettes) were the most commonly used tobacco product among U.S. middle school and high school students in 2016 (1). CDC and the Food and Drug Administration (FDA) analyzed data from the 2016 National Youth Tobacco Survey (NYTS) to assess self-reported reasons for e-cigarette use among U.S. middle school (grades 6-8) and high school (grades 9-12) student e-cigarette users. Among students who reported ever using e-cigarettes in 2016, the most commonly selected reasons for use were 1) use by "friend or family member" (39.0%); 2) availability of "flavors such as mint, candy, fruit, or chocolate" (31.0%); and 3) the belief that "they are less harmful than other forms of tobacco such as cigarettes" (17.1%). The least commonly selected reasons were 1) "they are easier to get than other tobacco products, such as cigarettes" (4.8%); 2) "they cost less than other tobacco products such as cigarettes" (3.2%); and 3) "famous people on TV or in movies use them" (1.5%). Availability of flavors as a reason for use was more commonly selected by high school users (32.3%) than by middle school users (26.8%). Efforts to prevent middle school and high school students from initiating the use of any tobacco product, including e-cigarettes, are important to reduce tobacco product use among U.S. youths (2).

The purpose of this study was to investigate susceptibility and ever use of tobacco products among adolescents and young adults in the US. Cross-sectional analysis of Wave 1(2013-2014) adolescent (12-17year-olds; n=13,651) and young adult (18-24year-olds; n=9112) data from the nationally-representative Population Assessment of Tobacco and Health (PATH) Study was conducted. At 12years, 5% were ever tobacco users and 36% were susceptible to use. Seventy percent were susceptible at age 17years, and the same proportion were ever users at age 22years. Susceptibility levels were comparable for cigarettes and e-cigarette (28.6% and 27.4%, respectively), followed by hookah (22.0%), pipes (17.5%), cigars (15.2%), and smokeless tobacco (9.7%). Non-Hispanic (NH) Black (Adjusted Odds Ratio [ORadj]=1.36; 95% Confidence Limit [CL], 1.18-1.56) and Hispanic (ORadj=1.34: 95% CL,1.19-1.49) adolescent never- users were more likely to be susceptible to future use of a tobacco product than NH Whites. Susceptibility was higher with age (15-17yrs. vs 12-14yrs.: ORadj=1.69; 95% CL, 1.55-1.85) and parental education (college graduates vs less than HS education: ORadj=1.22, 95% CL, 1.08-1.39). Compared to exclusive users of hookah, cigars, or smokeless products, larger proportions of exclusive e-cigarette ever users were also susceptible to cigarette use. Among adolescents, lower levels of ever use of tobacco products are often counterbalanced by higher levels of susceptibility for future use, which may suggest delayed initiation in some groups. Ever users of a given tobacco product were more susceptible to use other tobacco products, putting them at risk for future multiple tobacco product use.

BACKGROUND: Electronic cigarette (e-cigarette) use in the USA is increasing. As such, it is critical to understand who uses e-cigarettes, how e-cigarettes are used and what types of products are prevalent. This study assesses patterns of current e-cigarette use among daily and non-daily adult users in the 2013-2014 Population Assessment of Tobacco and Health (PATH) Study. METHODS: We examined the proportion of current adult e-cigarette users (n=3642) reporting infrequent use (use on 'some days' and use on 0-2 of the past 30 days), moderate use (use on 'some days' and use on >2 of the past 30 days) and daily use. We examined demographic characteristics, use of other tobacco products and e-cigarette product characteristics overall and by use category. Adjusted prevalence ratios (aPRs) were calculated using Poisson regression to assess correlates of daily e-cigarette use. RESULTS: Among the 5.5% of adult current e-cigarette users in the PATH Study, 42.2% reported infrequent use, 36.5% reported moderate use and 21.3% reported daily use. Cigarette smokers who quit in the past year were more likely to report daily e-cigarette use, compared with current smokers (aPR=3.21, 95% CI=2.75 to 3.76). Those who reported using rechargeable or refillable devices were more likely to report daily use compared with those who did not use these devices (aPR=1.95, 95% CI=1.44 to 2.65 and aPR=2.10, 95% CI=1.75 to 2.52, respectively). CONCLUSIONS: The majority of e-cigarette users in this study reported less than daily use. Compared with non-daily use, daily use was associated with being a former smoker; however, cross-sectional data limits our ability to establish the temporality or directionality of such associations.

INTRODUCTION: The consumption of cigar products has increased since 2000. The multiple product types within this category, combined with the varied language with which consumers refer to them, present challenges for accurately assessing the prevalence of cigar product use. Surveillance is also complicated by the fact that these products can be used to smoke marijuana, as "blunts"-cigars in which the tobacco is removed and replaced with marijuana. Few studies exist regarding the language and terminology used to describe these products. METHODS: Sixteen focus groups were conducted in five cities in the United States between March and May of 2014. Participants (N = 123) included adults who had used cigars, cigarillos, or little cigars in the past 30 days. A semi-structured moderator guide was used to gather data on the terms used to identify cigar product subtypes and the language used to describe the products and their use. RESULTS: Participants used a variety of terms for each product subtype. Brand names were often used, as well as slang terms, including terms describing cigars modified for marijuana use. Some subtypes were less likely than others to be considered "cigars." Participants had mixed opinions about whether users of cigar products are "smokers." CONCLUSIONS: Users of cigar products may classify or label products differently from researchers and policy makers, and many refer to their product by brand name or a slang term. These findings have implications for future research, instrument design, and public health messaging about cigar products. IMPLICATIONS: This study adds to the body of evidence highlighting the challenges for measurement and surveillance of non-cigarette tobacco products, including cigars. Findings illustrate the myriad terms used by consumers to describe their use of cigar product subtypes, as well as the complexity of distinguishing between use of cigar products as intended, versus as a vehicle for smoking marijuana. Future research aimed to enhance specificity of cigar use measures will enable policy-makers and public health practitioners to more fully characterize prevalence and patterns of use by cigar subtype.

INTRODUCTION: Use of electronic nicotine delivery systems (ENDS), including electronic cigarettes (e-cigarettes), is increasing. One concern is the appeal of these products to youth and young adults and the potential to influence perceptions and use of conventional cigarettes. METHODS: Using data from the 2012-2013 National Adult Tobacco Survey, characteristics of adults aged 18-29 years who had never established cigarette smoking behavior were examined by ever use of e-cigarettes, demographics, and ever use of other tobacco products (smokeless tobacco, cigars, hookah, and cigarettes). Multivariate logistic regression was used to examine the relationship between e-cigarette use and openness to cigarette smoking among young adults, defined as the lack of a firm intention not to smoke soon or in the next year. RESULTS: Among young adults who had never established cigarette smoking behavior (unweighted n = 4,310), 7.9% reported having ever tried e-cigarettes, and 14.6% of those who reported having ever tried e-cigarettes also reported current use of the product. Ever e-cigarette use was associated with being open to cigarette smoking (adjusted odds ratio = 2.4; 95% confidence interval = 1.7, 3.3), as was being male, aged 18-24 years, less educated, and having ever used hookah or experimented with conventional cigarettes. CONCLUSIONS: Ever use of e-cigarettes and other tobacco products was associated with being open to cigarette smoking. This study does not allow us to assess the directionality of this association, so future longitudinal research is needed to illuminate tobacco use behaviors over time as well as provide additional insight on the relationship between ENDS use and conventional cigarette use among young adult populations.

INTRODUCTION: Electronic cigarette (e-cigarette) use is increasing rapidly, and the impact on youth is unknown. We assessed associations between e-cigarette use and smoking intentions among US youth who had never smoked conventional cigarettes. METHODS: We analyzed data from the nationally representative 2011, 2012, and 2013 National Youth Tobacco Surveys of students in grades 6-12. Youth reporting they would definitely not smoke in the next year or if offered a cigarette by a friend were defined as not having an intention to smoke; all others were classified as having positive intention to smoke conventional cigarettes. Demographics, pro-tobacco advertisement exposure, ever use of e-cigarettes, and ever use of other combustibles (cigars, hookah, bidis, kreteks, and pipes) and noncombustibles (chewing tobacco, snuff, dip, snus, and dissolvables) were included in multivariate analyses that assessed associations with smoking intentions among never-cigarette-smoking youth. RESULTS: Between 2011 and 2013, the number of never-smoking youth who used e-cigarettes increased 3-fold, from 79,000 to more than 263,000. Intention to smoke conventional cigarettes was 43.9% among ever e-cigarette users and 21.5% among never users. Ever e-cigarette users had higher adjusted odds for having smoking intentions than never users (adjusted odds ratio = 1.70, 95% confidence interval = 1.24-2.32). Those who ever used other combustibles, ever used noncombustibles, or reported pro-tobacco advertisement exposure also had increased odds for smoking intentions. CONCLUSION: In 2013, more than a quarter million never-smoking youth used e-cigarettes. E-cigarette use is associated with increased intentions to smoke cigarettes, and enhanced prevention efforts for youth are important for all forms of tobacco, including e-cigarettes.

The burden of death and disease from tobacco use in the United States has been caused overwhelmingly by cigarettes and other smoked tobacco products. In the United States, cigarette consumption declined during 2000-2011; however, consumption of cigars more than doubled during the same period. The cigar market includes diverse product types manufactured with a variety of shapes and sizes, filters, tips, flavors, and prices. Although national estimates of cigar consumption have been reported previously, data characterizing who smokes different cigar types are limited. A recent analysis from the 2012-2013 National Adult Tobacco Survey (NATS) found that more than one in 20 U.S. adults smoke cigars "every day," "someday," or "rarely". This report expands upon those findings, using data from the 2012-2013 NATS to further characterize cigar smokers by the usual type of cigar smoked using the following categories: little filtered cigars (LFCs), cigarillos/other mass market cigars (cigarillos/MMCs), and premium cigars. The findings indicate that among U.S. adults who smoke cigars, 61.8% usually smoke cigarillos/MMCs, 19.9% usually smoke premium cigars, and the remainder, 18.4%, usually smoke LFCs. These data can help to inform public health interventions to reduce the burden of adverse health effects caused by cigar smoking in the United States, including regulation.

BACKGROUND: Previous studies have examined the characteristics of open and closed system electronic nicotine delivery system (ENDS) users, but population-level information on nicotine exposure among these users has not been available. METHODS: We analyzed nicotine biomarker and survey data from Wave 3 of the Population Assessment of Tobacco and Health (PATH) study collected from October 2015 to October 2016. We identified 277 exclusive ENDS users and 468 dual cigarette and ENDS users and analyzed concentrations of nicotine and its metabolites obtained from urine samples by device type and other characteristics, such as frequency of use and e-liquid flavor. RESULTS: Among exclusive ENDS users, open system users had higher levels of total nicotine exposure (TNE-2) than closed system users [8.8 µmol/g creatinine (95% confidence interval [CI] = 5.3-14.8 µmol/g vs. 2.0 µmol/g (95% CI = 0.7-5.4 µmol/g)]. However, TNE-2 concentrations were similar when open and closed system users were stratified as daily [26.4 µmol/g (95% CI = 20.1-34.7 µmol/g) vs. 27.1 µmol/g (95% CI = 16.4-44.9 µmol/g)] and nondaily [0.5 µmol/g (95% CI = 0.1-1.9 µmol/g) vs. 0.2 µmol/g (95% CI = 0.0-0.7 µmol/g)] ENDS users. Dual users generally had higher nicotine exposure than exclusive users. CONCLUSIONS: Nicotine exposure was observed to be higher among exclusive open system ENDS users compared with closed system users, but levels were similar when users were stratified by frequency of use. IMPACT: These results suggest that exclusive ENDS users with similar use patterns receive comparable levels of nicotine, regardless of whether they use open or closed system devices.

BACKGROUND: More smokers report using e-cigarettes to help them quit than FDA-approved pharmacotherapy. OBJECTIVE: To assess the association of e-cigarettes with future abstinence from cigarette and tobacco use. DESIGN: Cohort study of US sample, with annual follow-up. PARTICIPANTS: US adult (ages 18+) daily cigarette smokers identified at Wave 1 (W1; 2013-14) of the PATH Study, who reported a quit attempt before W2 and completed W3 (n = 2443). EXPOSURES: Use of e-cigarettes, pharmacotherapy (including nicotine replacement therapy), or no product for last quit attempt (LQA), and current daily e-cigarette use at W2. ANALYSIS: Propensity score matching (PSM) of groups using different methods to quit. OUTCOME MEASURES: 12+ months abstinence at W3 from cigarettes and from all tobacco (including e-cigarettes). 30+ days abstinence at W3 was a secondary outcome. RESULTS: Among daily smokers with an LQA, 23.5% used e-cigarettes, 19.3% used pharmacotherapy only (including NRT) and 57.2% used no product. Cigarette abstinence for 12+ months at W3 was ~10% in each group. Half of the cigarette abstainers in the e-cigarette group were using e-cigarettes at W3. Different methods to help quitting had statistically comparable 12+ month cigarette abstinence at W3 (e-cigarettes vs no product: Risk Difference (RD) = 0.01, 95% CI: -0.04 to 0.06; e-cigarettes vs pharmacotherapy: RD = 0.02, 95% CI:-0.04 to 0.09). Likewise, daily e-cigarette users at W2 did not show a cessation benefit over comparable no-e-cigarette users and this finding was robust to sensitivity analyses. Abstinence for 30+ days at W3 was also similar across products. LIMITATIONS: The frequency of e-cigarette use during the LQA was not assessed, nor was it possible to assess continuous abstinence from the LQA. CONCLUSION: Among US daily smokers who quit cigarettes in 2014-15, use of e-cigarettes in that attempt compared to approved cessation aids or no products showed similar abstinence rates 1-2 years later.

Serious injuries may result from electronic nicotine delivery systems (ENDS) battery malfunctions, including overheating, fires, and explosions (O/F/E). This pilot study assessed the usefulness of social media monitoring as a tool for gathering information surrounding ENDS battery O/F/E, including changes in the volume and nature of social media mentions over time. Brandwatch, a social media monitoring tool, was queried to examine ENDS battery-related O/F/E over a one-month period, annually, from 2013-2017. Two researchers qualitatively coded the social media mentions for relevance and coded the relevant mentions by event type and theme. The total number of mentions coded as relevant (n = 947) for the one-month period increased each year. Mentions of first-person events were relatively infrequent (3.6% of relevant mentions), while mentions describing events that happened to someone else increased over time (60.4% of relevant mentions). A relatively small proportion of mentions expressed concern around a potential event and advice on how to prevent future events (4.8% and 10.5% of relevant mentions, respectively). Findings suggest that social media mentions around ENDS battery O/F/E events have increased over recent years. Social media monitoring can complement traditional surveillance systems to elucidate the extent to which ENDS O/F/E events are occurring.

To date no study has reported U.S. nationally representative estimates of current ENDS users by device category ("open" vs. "closed" systems) nor their detailed use behaviors. We examined the proportion of current adult ENDS users (unweighted n = 2671) using either "closed" or "open" systems during Wave 3 (2015-2016) of the Population Assessment of Tobacco and Health (PATH) Study. Demographic characteristics, use patterns, and device characteristics were examined overall and by device type. Among the 5.0% of current users at Wave 3, 43.9% used closed systems and 53.7% used open systems. Compared to closed system users, open system users were more likely to be male (60.7% vs. 48.4%), aged 18-24 (30.4% vs. 21.4%), and non-Hispanic White (76.2% vs. 65.4%), recent former (9.9% vs. 5.6%) or long-term former (20.2% vs. 10.9%) smokers, and use ENDS daily (44.1% vs. 22.5%); they were less likely to be to be current daily smokers (31.7% vs. 48.0%) or never smokers (15.2% vs. 19.5%). Adult ENDS users were nearly evenly split on their use of closed versus open systems; however, several group differences were observed. Disentangling the relationship between device selection and subsequent use patterns remains a public health priority.

INTRODUCTION: Tobacco use disparities by sexual identity are well characterized among adults, but relatively less is known about tobacco use disparities in sexual minority youth. Moreover, no national study has reported tobacco use behaviors among gender minority (e.g., transgender) youth. METHODS: Data from Wave 3 (2015-2016) of the Population Assessment of Health Study from youth aged 14-17 years (n=7,772), analyzed in 2018, were stratified by transgender identity, sex, and sexual identity to describe tobacco product use. RESULTS: Transgender youth (n=79) were more likely to report ever use of tobacco products compared with nontransgender youth (electronic nicotine products, 40.2% vs 23.0%; cigarettes, 33.9% vs 14.1%; and smokeless tobacco, 21.5% vs 6.0%, respectively) and more likely to report past 30-day use of these products. Similarly, female sexual minority youth, compared with straight female youth, were more likely to report ever use of electronic nicotine products (37.9% vs 20.1%); cigarettes (28.9% vs 12.0%); cigars (11.3% vs 5.2%); hookah (12.7% vs 7.6%); and past 30-day use of electronic nicotine products, cigarettes, and cigars. Among male youth, sexual minority youth were more likely to report ever use of cigarettes compared with straight youth (25.1% vs 13.5%), but they did not differ in ever or past 30-day use of any other tobacco products. CONCLUSIONS: Sexual minority youth and transgender youth are more likely to use tobacco products compared with their nonminority peers. Similar to patterns among adults, this is especially true for female sexual minority youth. This information is useful for developing communication and education efforts to prevent youth tobacco initiation in these high-risk groups.

INTRODUCTION: 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 12-17â¯years) who had ever heard of e-cigarettes at baseline of the PATH Study (nâ¯=â¯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 rangeâ¯=â¯1.6-6.8) and cigarette only smokers had higher odds of other (non-e-cigarette) tobacco use (aOR rangeâ¯=â¯1.5-2.3), marijuana use (aORâ¯=â¯1.9, 95%CIâ¯=â¯1.4-2.5), a high GAIN substance use score (aORâ¯=â¯1.9, 95%CIâ¯=â¯1.1-3.4), low academic achievement (aOR rangeâ¯=â¯1.6-3.4), and exposure to smoking (aOR rangeâ¯=â¯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.

INTRODUCTION: Assessing the extent that cigarette smokers use or switch to e-cigarettes and smokeless tobacco can help inform the population health impact of these products. This study estimated the prevalence of e-cigarette and smokeless tobacco use and switching among current and recent former adult cigarette smokers. METHODS: Data from the 2012-2013 (n=8,891) and 2013-2014 (n=11,379) National Adult Tobacco Survey were analyzed in 2016. Response rates for this telephone survey were 44.9% and 36.1%, respectively. Tobacco product use was assessed by smoking status. RESULTS: Current e-cigarette use increased for all groups, with a greater increase among recent quitters, 9.1% (95% CI=7.1%, 11.1%) in 2012-2013 and 15.8% (95% CI=13.7%, 17.9%) in 2013-2014, than smokers with an unsuccessful quit attempt, 10.4% (95% CI=9.1%, 11.7%) in 2012-2013 and 14.8% (95% CI=13.5%, 16.1%) in 2013-2014, or smokers with no quit attempt, 5.9% (95% CI=4.8%, 6.9%) in 2012-2013 and 10.7% (95% CI=9.4%, 12.0%) in 2013-2014. Between 2012-2013 and 2013-2014, current use of smokeless tobacco remained steady for recent quitters (4.6% to 4.7%, p=0.92) and smokers with no quit attempt (4.0% to 4.3%, p=0.97), and decreased in smokers with an unsuccessful quit attempt (5.7% to 3.8%, p=0.004). More recent quitters completely switched to e-cigarettes in the past year (15.3% in 2012-2013, 25.7% in 2013-2014) than to smokeless tobacco (4.6% in 2012-2013, 4.5% in 2013-2014). CONCLUSIONS: Current and recent former adult smokers are more likely to use e-cigarettes than smokeless tobacco. Current e-cigarette use was most prevalent among unsuccessful quitters and recent quitters, who were substantially more likely to report complete switching to e-cigarettes than smokeless tobacco.

More than half of adult tobacco users in the United States (U.S.) transitioned in tobacco product use between 2013â»2014 and 2014â»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, 2013â»2014) and Wave 2 (W2, 2014â»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.

In 2013â»2014, nearly 28% of adults in the United States (U.S.) were current tobacco users with cigarettes the most common product used and with nearly 40% of tobacco users using two or more tobacco products. We describe overall change in prevalence of tobacco product use and within-person transitions in tobacco product use in the U.S. between 2013â»2014 and 2014â»2015 for young adults (18â»24 years) and older adults (25+ years). Data from Wave 1 (W1, 2013â»2014) and Wave 2 (W2, 2014â»2015) of the Population Assessment of Tobacco and Health (PATH) Study were analyzed (N = 34,235). Tobacco product types were categorized into: (1) combustible (cigarettes, cigars, pipe tobacco, hookah), (2) noncombustible (smokeless tobacco, snus pouches, dissolvable tobacco), and (3) electronic nicotine delivery systems (ENDS). Transitions for individual combustible-product types, and for single- and multiple-product use, were also considered. Overall prevalence of current tobacco use decreased from 27.6% to 26.3%. Among W1 non-tobacco users, 88.7% of young adults and 95.8% of older adults were non-tobacco users at W2. Among W1 tobacco users, 71.7% of young adults transitioned, with 20.7% discontinuing use completely, and 45.9% of older adults transitioned, with 12.5% discontinuing use completely. Continuing with/transitioning toward combustible product(s), particularly cigarettes, was more common than continuing with/transitioning toward ENDS. Tobacco use behaviors were less stable among young adults than older adults, likely reflecting greater product experimentation among young adults. Relative stability of cigarette use compared to other tobacco products (except older adult noncombustible use) demonstrates high abuse liability for cigarettes.
