Introduction: Given the negative health outcomes of tobacco and cannabis co-use, understanding the co-use of tobacco and cannabis is important, particularly regarding those with higher health burdens, such as sexual minority individuals. This study examined the co-use of tobacco and cannabis by sexual identity., Methods: The adult sample from the 2022 National Survey on Drug Use and Health (NSDUH) was used for this study. A multinomial logistic regression was performed on past-month tobacco and cannabis use (i.e., no use of tobacco and cannabis [reference], tobacco only use, cannabis only use, tobacco and cannabis co-use) by sexual identity (i.e., heterosexual (reference), gay/lesbian, bisexual), adjusting for demographics. Data were collected in 2022, and statistical analyses were performed in 2024., Results: Among the overall adult sample, 15.8% (weighted) reported past-month tobacco only use, 7.4% reported past-month cannabis only use, and 8.5% reported past-month tobacco and cannabis co-use. Among female adults, tobacco and cannabis co-use was more likely to be reported by lesbian females (aRRR=3.83, 95% CI=2.51, 5.84) and bisexual females (aRRR=6.48, 95% CI=5.17, 8.11), compared with heterosexual females. Among male adults, tobacco and cannabis co-use was more likely to be reported by gay males (aRRR=1.68, 95% CI=1.05, 2.68) and bisexual males (aRRR=1.94, 95% CI=1.42, 2.66), compared with heterosexual males., Conclusions: This study observed high levels of tobacco and cannabis co-use among sexual minority individuals. Future research should examine factors that influence tobacco and cannabis co-use for sexual minority individuals., Competing Interests: Conflict of Interest There is no conflict of interest in this study., (Copyright © 2024.

Objective: Sexual minority (SM) women experience tobacco-related disparities and report a higher prevalence of cigarette use, as well as subgroup differences in use, but little is known about their quitting behavior. This study used data from a national sample of United States SM women to examine cigarette quit ratios overall and by age, race/ethnicity, and sexual orientation., Methods: Using baseline survey data from the Generations Study (2016-2017, N = 812), we calculated quit ratios among SM women reporting lifetime smoking (100+ cigarettes) who reported currently smoking "not at all" relative to those reporting smoking "every day or some days." Quitting was compared across cohort, race/ethnicity, and sexual orientation, controlling for household income., Results: SM women reporting lifetime smoking in the older cohort were significantly more likely to report quitting than those in the younger cohort. Bisexual women also reported a greater likelihood of quitting than gay/lesbian women. There was no association between race/ethnicity and the probability of quitting smoking., Conclusions: SM women remain a priority for tobacco prevention and cessation efforts. There is evidence that the probability of quitting cigarettes differs across sexual orientation and age cohorts, which has implications for tailoring of interventions and tobacco communications., Competing Interests: Declaration of competing interest The authors have no conflicts of interest., (Copyright © 2024.

Purpose: Tobacco use is a major health disparity for lesbian, gay, bisexual, and transgender (LGBT) populations compared with heterosexual/cisgender populations. In this scoping review, we aimed to determine if LGBT tobacco use disparities are improving or worsening over time and if trends in disparities differed across subgroups. Methods: We included articles that longitudinally explored youth and adult LGB tobacco use in the United States and Canada after searching four databases and capturing records through July 2022. Two reviewers independently screened the title/abstract and full text of 2326 and 45 articles, respectively. Eleven articles from 18 larger assessments met inclusion criteria, spanning data collection from 1996 to 2020. Results: All studies consistently demonstrated tobacco disparities for LGB populations. No articles examined longitudinal transgender tobacco disparities. Most studies focused on smoking combustible cigarettes. Disparities in heavy or daily use for all LGB youth subgroups compared with heterosexual samples appear to be shrinking longitudinally. Results for early-onset, current, and lifetime smoking were less consistent. Adult evidence was relatively sparse; however, after 2010, studies show diminishing disparities over time, except for current smoking by bisexual women. Conclusions: Large tobacco use disparities persist for LGB populations, although the size of disparities may be decreasing for some groups. Initiatives for lesbian and bisexual women and girls should be prioritized, in addition to interventions addressing LGB smoking broadly. Surveillance instruments should uniformly and consistently assess LGBT identities and tobacco use behaviors.

Background: Adverse childhood experiences (ACEs) predict low education and low income, but this has scarcely been examined by sexual orientation and gender identity., Objective: We investigated prevalence and associations between ACEs, low income, and low education in sexual and gender diverse (SGD) and cisgender heterosexual (CGH) sub-groups., Participants and Setting: Data came from 14 states in the 2019 Behavioral Risk Factor Surveillance System survey (n = 79,303)., Methods: Chi-square, logistic regression, and moderation analyses were implemented to examine the prevalence and associations between ACEs, low income, and low education. Sample stratification was used to examine differences between SGD and CGH sub-groups., Results: SGD participants reported higher prevalence of ACEs, low income, and low education compared to CGH participants (p < 0.0001) with the highest proportions in transgender and queer/something else groups. ACEs were associated with low income (AOR 1.084, CI 1.067-1.102) and low education (AOR 1.056, CI 1.041-1.071) in the entire sample. Transgender and queer/something else groups had higher odds of low income (AOR 3.345, CI 1.975-5.665; AOR 1.702, CI 1.096-2.643) and low education (AOR 1.702, CI 1.096-2.643; AOR 3.552, CI 2.842-4.440) and gay/lesbian identity had reduced odds of low education (AOR 0.586, CI 0.457-0.751) compared to CGH males. The strength of associations between ACEs and low income and low education were weaker among SGD compared to CGH sub-groups., Conclusion: These findings highlight the importance of including categories of sexual identity cross-classified by gender identity in population-based analyses in order to facilitate a comprehensive characterization of the life course outcomes of SGD populations., Competing Interests: Declaration of competing interest The authors have no conflicts of interest to disclose., (Copyright © 2023 Elsevier Ltd.

Aims: To measure longitudinal trajectories of marijuana use in four tobacco/nicotine products (hand-rolled cigarettes/spliffs, cigars/blunts, hookah, and e-cigarettes) among young adult Texas college students from 2015 to 2019., Design: This study used six consecutive waves of data from the marketing and promotions across colleges in Texas project (Project M-PACT), a longitudinal study of the tobacco behaviors of young adult college students. The first four waves were collected every 6 months (fall 2015-spring 2017), and the final two waves were conducted yearly (spring 2018 and 2019). Growth curve models measured trajectories of marijuana use in tobacco products across the 3.5-year period., Setting and Participants: A total of 4857 young adults from 24 colleges in the largest metropolitan areas of Texas, United States (Austin, Dallas, Houston, and San Antonio): mean age = 21.0, SD = 2.3; 64.2% assigned female; 36.1% non-Hispanic white, 31.0% Hispanic, and 33.0% other or combination race/ethnicity., Measurements: Participants completed online surveys assessing their past 6-month use of marijuana in four tobacco products of interest (spliffs, blunts, hookah, and e-cigarettes) and socio-demographic variables (sex, race/ethnicity, age, 2-year/4-year college attendance, and sexual and gender minority identity)., Findings: Observed vaping marijuana in e-cigarettes approximately doubled between the spring of 2015 and the spring of 2019, from 11.8% to 23.9% following a quadratic time trend (linear OR = 0.84, 95% CI = 0.73-0.97, quadratic OR = 1.18, CI = 1.13-1.22). This same time period saw a quadratic decline in using marijuana in hookah (P < 0.001) and no changes in using hand-rolled cigarettes/spliffs or cigars/blunts for marijuana delivery., Conclusions: The popularity of nicotine e-cigarettes appears to be expanding the avenues for marijuana delivery among young adults in Texas, United States., (© 2022 Society for the Study of Addiction.)

Introduction: To eliminate tobacco-related disparities, tobacco control research would benefit from a paradigm shift. Intersectionality, a framework pioneered by Kimberlé Crenshaw in late 1980s, has the potential to improve our understanding of why and how certain social groups are disproportionately harmed by commercial tobacco use, and improve our ability to address persistent tobacco-related health disparities., Aims and Methods: In this commentary, we outline the rationale and recommendations for incorporating intersectionality into equity-minded tobacco control research. These recommendations arose from intersectionality webinars organized by the Health Disparities (now Health Equity) Network of the Society for Research on Nicotine & Tobacco (SRNT) in 2019 and 2020., Results: Specifically, we propose that eliminating tobacco-related disparities through intersectionality-informed research requires a multilevel, multipronged approach. We summarize priority actions for the tobacco control research field to achieve health equity through the intersectionality framework including acknowledging that structural factors, racism and power dynamics shape lived experiences, integrating critical theoretical frameworks and intersectionality scholarship into research questions, and embracing collaborative community-based approaches at every level of the research process., Conclusions: Through these actions, our field can take concrete steps to fundamentally improve our approach to conducting research to achieve health equity., Implications: Intersectionality is a valuable tool to align our field with our pursuit of health equity. The recommendations aim to improve methods of equity-focused tobacco control, prompt ongoing dialogue on the utility of this tool, and shift paradigms in how the research process is conducted at every level among stakeholders, including researchers, journal editors and reviewers, funders, practitioners, and policy makers., (© The Author(s) 2022.

Aside from prevalence estimates and comparisons to heterosexual and presumed cisgender (i.e., not transgender) samples, little is known about transgender and gender diverse (TGD) young adult tobacco use. This study explored reasons and contexts TGD young adults used a variety of tobacco products through 25 one-on-one semi-structured qualitative interviews in 2018. Thematic analysis yielded four themes: (1) smoking in response to anxiety, depression, or stress, (2) social smoking, (3) accepting smoking-related norms, and (4) appealing aspects of tobacco. The first three themes contained elements specifically tied to TGD identity; the final theme related to perceptions of tobacco unrelated to identity. Findings suggest reasons for smoking that are unique to TGD young adults, who frequently reported smoking cigarettes as a coping response to an amalgam of stressors. Accounting for unique stressors related to TGD identity will assist in developing culturally relevant interventions to reduce the disproportionate tobacco burden in TGD communities.

Introduction: Research has demonstrated disparities in depressive symptoms among people who are marginalized. However, more work should examine depressive symptoms through an intersectional lens, recognizing that multiple systems of privilege and oppression interlock to create unique struggles where multiple marginalized identities meet. Recent methodological developments have advanced quantitative intersectionality research using multilevel modeling to partition variance in depressive symptoms to person-level sociodemographic variables and intersectional-level social strata. The purpose of this study is to leverage these methods to examine trajectories of depressive symptoms among young adults in Texas through an intersectional lens., Methods: Multilevel modeling was used to examine the longitudinal trajectories of depressive symptoms among 3575 young adults from 24 colleges in Texas assessed seven times between Fall 2014 and Spring 2018. Intersectional identities included sex, race/ethnicity, and sexual and gender minority identities. The model examined time nested within individuals and individuals nested within intersectional social strata., Results: Young adults in Texas experienced an increase in depressive symptoms from 2014-2018. Those with female, Hispanic, AAPI, other race/ethnicity, or LGBTQ + identities experienced more depressive symptoms. After controlling for the main effects of the sociodemographic variables, 0.08% of variance in depressive symptoms remained attributed to the effects of intersectional identities., Conclusion: Evaluating disparities in depressive symptoms through an intersectional lens offers a more complete description of the epidemiology of depressive symptoms. Communities and institutions that serve marginalized people should consider the elevated burden of depressive symptoms that marginalized people may carry, and integrate culturally competent psychoeducation, assessments, and therapies where possible., (© 2022.

Introduction: Tobacco interventions specifically created for transgender and gender diverse young adults appear almost non-existent. The Food and Drug Administration's This Free Life is the first large scale campaign specifically designed to address the smoking disparities of sexual and gender minority (SGM) young adults. The purpose of this study was to gauge the reactions and receptivity to This Free Life from a gender diverse young adult sample using interviews conducted in spring and summer 2018., Methods: Participants were 25 young adults recruited in Austin, Texas (M age = 23.2, 64.0 % non-Hispanic White, 70 % assigned female at birth) for semi-structured one-on-one interviews as part of a larger project focusing on the reasons and settings for tobacco use. Data in the current study pertain to attitudes and reactions to online video content from This Free Life., Results: Positive reactions to video content related to visible queer representation and depictions of gender non-conformity in videos that were positive and affirming in tone. Negative reactions related to what was perceived as sexist stereotypes perpetuated in videos, and an over-reliance on cisgender gay bar culture. Some participants felt that messaging discouraging social/occasional smoking did not take into account their own important reasons for smoking., Conclusions: Transgender and gender diverse young adults have been overlooked in many efforts to address SGM smoking disparities. Targeted efforts such as This Free Life have the potential to help curb the disproportionate tobacco burden of gender diverse young adults by including diverse gender representation in affirming messages that emphasize freedom and autonomy., (Copyright © 2020 Elsevier B.V.

Introduction: Sexual and gender minority (SGM) individuals have higher tobacco use prevalence and consequently higher burden of tobacco-caused diseases, including cancer and cardiovascular disease compared with their heterosexual or cisgender counterparts. Yet, there is a critical gap in research focused on measuring SGM tobacco-related health disparities and addressing unmet needs of SGM individuals in the context of nicotine and tobacco research., Aims and Methods: In this commentary, we summarize recommendations discussed during a pre-conference workshop focused on challenges and opportunities in conducting SGM tobacco control research at the 2019 Society for Research on Nicotine and Tobacco Annual Meeting., Results: Specifically, we recommend defining and measuring SGM identity in all nicotine and tobacco research routinely, using novel methods to engage a demographically diverse sample of the SGM population, and eliciting SGM community voices in tobacco control research., Conclusions: Addressing these critical research gaps will enable the scientific community to generate the data to fully understand and support SGM individuals in tobacco use prevention and cessation., Implications: Tobacco use and its consequences have become increasingly concentrated in disadvantaged groups, including sexual and gender minority (SGM) populations. Through concrete recommendations in this commentary, we aimed to promote health equity, diversity, and inclusion in tobacco research for SGM populations by urging the scientific community to consider expanding efforts to monitor and address tobacco-related health disparities of SGM populations within their respective research programs., (© The Author(s) 2020.

Introduction: Polytobacco use is a growing concern; users are exposed to cumulatively more nicotine, increasing their risk for dependence and long-term use. More sexual minority (SM) young adults report polytobacco use than their heterosexual peers, yet no studies explore how their tobacco patterns vary across the diverse product landscape. The purpose of this study was to characterize SM young adults' patterns of tobacco use and nicotine dependence, and explore co-occurring risk factors for polytobacco use., Methods: Participants were 609 SM Texas college students. Latent class analysis identified subgroups of tobacco users based on their tobacco use behaviors and an indicator of nicotine dependence. Multinomial logistic regression identified associations between individual-level variables and the probability of membership in various user classes., Results: Tobacco use clustered in four classes: non-users, non-addicted cigarette users, non-addicted e-cigarette users, and addicted polytobacco users. Polytobacco users had an increased probability of depressive symptoms and cannabis use relative to non-users, and more binge alcohol use than all other groups. Non-addicted cigarette users had an increased probability of binge alcohol use, cannabis use, and being non-Hispanic White relative to non-users, and an increased likelihood of cannabis use relative to non-addicted e-cigarette users. Non-addicted e-cigarette users had an increased probability of binge alcohol use relative to non-users., Conclusions: SM young adults' tobacco use varies across the diverse product landscape. Failing to account for a range of tobacco behaviors and nicotine dependence prevents tailoring interventions that should also address concerns such as depressive symptoms, cannabis use, and binge alcohol use., Competing Interests: Declaration of Competing Interest The authors declare no conflicts of interest., (Copyright © 2020.

Purpose: The purpose of this study was to compare characteristics of usual JUUL users versus other electronic nicotine delivery systems (ENDS) users, examine differences in reasons for use and perceptions across ENDS user groups, and identify significant correlates of usual JUUL use., Methods: This study used data from 510 young adult ENDS users (ages 18-29 years) from Wave 7 (Spring 2018) of the Marketing and Promotions Across Colleges in Texas Project (Project M-PACT). Chi-Square analyses, independent t-tests, and mixed-effects logistic regression analyses were conducted to identify factors associated with usual JUUL use. Four separate regression analyses were conducted based on independent variables of interest; all models included demographics and ENDS/other tobacco use behaviors as covariates., Results: Compared with other ENDS users, usual JUUL users were more likely to be male, younger, smoke cigarettes, reported a higher socioeconomic status (SES), used ENDS on more days in the past 30 days, and reported nicotine "hit" as a reason for use. Usual JUUL users had a higher prevalence of perceiving JUUL/pod vapes as addictive compared with other ENDS users, although perceived addictiveness was not significant in the multivariable models nor were the cessation and dependence measures different between ENDS user groups., Conclusions: Results highlight concerns about the dual use of JUUL and cigarettes and raise additional concerns about the high nicotine concentration of JUUL. Future longitudinal research is needed to determine if usual JUUL users are more likely to develop symptoms of nicotine dependence compared with other ENDS users., (Copyright © 2019 Society for Adolescent Health and Medicine.

United States (U.S.) veterans are prone to higher rates of smoking and smoking-related disease. We describe the prevalence of cigarette and non-cigarette product use and determine longitudinal predictors of tobacco use transitions in this vulnerable population. Data are from Waves 1 (2013-2014) and 2 (2014-2015) of the adult cohort in the Population Assessment of Tobacco and Health. Wave 1 prevalence was calculated for past 30-day use of all queried tobacco products, and compared by veteran status. Weighted multinomial logistic regression was used to determine predictors-demographics, substance use, and physical and psychological comorbidities-of tobacco use transitions (continued use, initiation, and cessation) among veterans. Compared to non-veterans, use of nearly all tobacco products was significantly higher among veterans and was highest among younger veterans. Compared to continued nonusers, continued users were more likely to: be of younger age (OR = 0.95, 95% CI: 0.95-0.96), have poorer physical health (OR = 1.58, 95% CI: 1.22-2.06) and mental health (OR = 1.48, 95% CI: 1.18-1.85), report substance use (OR = 1.79, 95% CI: 1.21-2.64), and report problematic alcohol use (OR = 4.23, 95% CI: 2.38-7.52) and were less likely to be female (OR = 0.57, 95% CI: 0.35-0.93). Compared to continued nonusers, initiators were more likely to report problematic alcohol use (OR = 8.63, 95% CI: 3.79-19.63), and those in the cessation category were more likely to be of younger age (OR = 0.97, 95% CI: 0.95-0.99). Cigarette and non-cigarette use is especially prevalent among young veterans, so prevention should begin during military service. Tobacco cessation programs should be tailored for this population, incorporating aspects related to concomitant health conditions., (© 2019 The Author(s).)

Introduction: We conducted a systematic review of the literature on cigar research on youth to identify potential future research agenda to generate evidence to inform cigar regulations to prevent cigar use among youth., Methods: We searched articles on Medline, EMBASE, and PsycINFO in April 2017 to identify articles relevant to cigars and adolescents. Two independent coders examined 48 articles to determine eligibility: (1) published between 2000-April 2017; (2) published in English; (3) conducted in the United States; (4) published in a peer-review journal; (5) examined cigars, cigarillos, or little cigars; (6) included youth (12-18 years old); and (7) included empirical data. Three independent coders reviewed the included articles (n = 48) to identify whether the studies addressed FDA's Research Priorities., Results: The studies addressed FDA's Research Priorities of "behavior" (n = 48), "communications" (n = 4), "marketing influences" (n = 1), and "impact analysis" (n = 1). Studies on "behavior" underscored the need for improvements in measurement, such as using brand names and distinguishing cigar products. The review revealed the need for restrictions on cigar flavors, development of media campaigns and interventions, increasing the cost (via taxation), and evaluating the impact of cigar policies., Conclusions: The studies mostly focused on surveillance of behaviors and use patterns, which revealed cigar specific issues to address in policies to decrease cigar use among youth. The lack of studies addressing other FDA's research priorities highlighted the critical need for future studies that inform prevention of youth cigar use., (Copyright © 2019 Elsevier Ltd.

Sexual minority (SM) young adults, such as those who identify as lesbian, gay, or bisexual (LGB), have well documented smoking disparities compared to heterosexual young adults. However, no studies have simultaneously tested the role of three risk factors (depressive symptoms, recalling tobacco marketing in bars, and cigarette-related social norms) to explain SM tobacco use disparities. Longitudinal structural equation modeling was used to explore if the association between SM identity and past 30-day cigarette smoking one year later was mediated by these three risk factors. Starting in fall 2015, three surveys were administered every 6 months to 3,972 young adult college students. Surveys assessed SM identity, depressive symptoms, tobacco marketing in bars, normative perceptions of cigarettes, and tobacco use behaviors. Greater depressive symptoms, recalling more tobacco marketing in bars, and more accepting cigarette-related social norms were each hypothesized to explain a unique portion of the association between SM identity and subsequent cigarette use. SM young adults reported higher prevalence of cigarette use, depressive symptom scores reflecting elevated risk for major depressive disorder, and more accepting cigarette-related social norms than their heterosexual peers. Results indicated that only cigarette-related social norms mediated the association between SM identity and subsequent past 30-day smoking, while controlling for depressive symptoms, recalling tobacco marketing in bars, sociodemographic factors, and previous tobacco use. Findings reflect a need for tailored tobacco control messaging that shift the more accepting cigarette-related norms of SM young adults, as doing so may ultimately lead to decreased smoking for this high-risk subgroup.

Background: Factors associated with marijuana use in electronic nicotine delivery systems (ENDS) are largely unknown. ENDS advertising, through subtle normative cues as well as explicit and implicit messages suggesting ENDS products are socially condoned and healthier alternatives, may influence the use of marijuana in ENDS. The aim of our study was to examine the association between exposure to ENDS advertising and subsequent use of ENDS with marijuana among college students., Methods: Data for this study were from waves 2 and 4 of the Marketing and Promotions across Colleges in Texas (M-PACT) study. Participants included 3720 college students (mean age = 21.4, SD = 2.3; 35.78% white; 35.7% male) across 24 colleges in Texas who completed online tobacco behavior surveys one year apart. Multilevel logistic regression was conducted to examine the association between ENDS advertising exposure at wave 2 (spring 2015) and use of marijuana in ENDS one year later at wave 4 (spring 2016), controlling for age, sex, race/ethnicity, and wave 2 sensation-seeking, impulsivity, current tobacco use, current marijuana use, and ever use of ENDS with marijuana. Use of ENDS to consume marijuana in the past six months was the outcome variable and ENDS advertising exposure was the independent variable., Results: Nearly half of participants reported ever ENDS use at waves 2 and 4, and 10% used marijuana in ENDS in the past 6-months at wave 4. Multilevel logistic regression analyses indicated that for every unit increase in ENDS advertising exposure, the odds of subsequently using ENDS with marijuana one year later were 1.08 times (95% CI = 1.01-1.14) greater., Conclusions: ENDS advertising uniquely contributed to the subsequent use of marijuana in an ENDS, over and above the effects of other risk factors., (Copyright © 2019 Elsevier Ltd.

Introduction: This study examined the association of sociodemographic characteristics, tobacco and substance use behaviors, and reasons to use cigars in young adults' flavored and non-flavored cigar use., Methods: Participants were 523, 18- to 29- year-old young adult college students (60.4% male; 40.9% non-Hispanic white) who reported current (past 30-day) cigar use., Results: Almost 75% of the sample regularly chose flavored cigar products. Multilevel logistic regression analyses indicated that younger, female, and racial/ethnic minority cigar users had significantly greater odds of using flavored cigars than their counterparts. Current marijuana smokers, ever-blunt smokers, and students who reported using cigars because they were affordable and/or available in flavors they liked had a greater odds of flavored cigar use compared to their counterparts. Moreover, among dual users of cigars and cigarettes, those who cited using cigars because they were cheaper than cigarettes and because cigars felt like smoking regular cigarettes had greater odds of using flavored cigars compared to their peers. Number of days cigars were smoked and current use of other tobacco products were not associated with flavored cigar use., Conclusions: Appealing attributes of flavored cigars have the potential to contribute to the tobacco use and subsequent nicotine addiction of younger, female, and racial/ethnic minority young adults. The wide variety of cigar flavors, their attractive price, and similarity to cigarette smoking underscore the need for additional research that links these unique traits to sustained tobacco use, and underscore the need for regulation of flavored products., Implications: This study extends the current literature by finding that younger, female, and racial/ethnic minorities have greater odds of flavored cigar use than their peers. Flavored cigars have characteristics that appeal to members of these populations, which can contribute to their long-term use and potential for addiction., (© The Author 2017.

Introduction: Most research regarding sexual and gender minority (SGM) populations is limited to examination of cigarette or general tobacco use or does not examine heterogeneity across SGM groups other than lesbian or gay and bisexual individuals. This study examined differences in the odds of current use and age of initiation of five tobacco/nicotine products among three groups of SGM young adults who self-identified as (1) gay or lesbian, (2) bisexual, and (3) queer, transgender, or "other," compared to their heterosexual peers., Methods: Participants were 4252 college students aged 18-29 years from 24 colleges in Texas who completed an online tobacco use survey. Multilevel logistic regression models were used to examine the odds of SGM participants currently using each tobacco product. Multilevel linear regression models were used to examine the association of current product users' SGM status with self-reported age of each product's initiation. All models were adjusted for sociodemographic factors and accounted for students clustered within each college., Results: At least one SGM group had significantly greater odds of currently using every tobacco product type compared to heterosexual participants, except hookah. There were few differences across groups in age of initiation. However, queer, transgender, and "other-" identified participants initiated e-cigarettes 1.34 years younger than heterosexual participants, and bisexual participants initiated smokeless tobacco 3.66 years younger than heterosexual participants., Conclusions: Findings highlight some significant tobacco use disparities among SGM young adults compared to their heterosexual peers. Longitudinal studies with larger group sizes will identify prospective predictors of sustained SGM-related tobacco use disparities., Implications: This study extends the current literature by including the sexual and gender minority identity options of queer, transgender, and "other," highlighting disparities in tobacco use between young adults in these subgroups compared to their heterosexual peers, particularly in noncigarette tobacco product use. Findings underscore the need for the Food and Drug Association and other health agencies to tailor health communication efforts specific to sexual and gender minority populations pertaining to the risks and harms surrounding tobacco product use., (© The Author 2017.

Introduction: Characteristics of electronic nicotine delivery systems (ENDS) make assessment of their use a challenge for researchers. Cognitive interviews are a way of gaining insight into participants' interpretations of survey questions and the methods they use in answering them, to improve survey tools., Methods: We used cognitive interviews to modify a young adult survey and improve assessment of quantity and frequency of ENDS use, as well as reasons for initiation and use of ENDS products. Twenty-five college students between the ages of 18 and 32 participated in individual cognitive interviews, which assessed question comprehension, answer estimation, retrieval processes, and answer response processes., Results: Comprehension issues arose discerning between ENDS device types (eg, cigalikes vs. vape pens), and answer estimation issues arose regarding ENDS use as drug delivery systems. These issues appeared to improve when pictures were added specifying the device in question, as well as when specific language naming nicotine as the ENDS product content was added to survey questions. Regarding answer retrieval, this sample of users had problems reporting their frequency of ENDS use, as well as quantifying the amount of ENDS products consumed (eg, volume of e-juice, number of cartridges, nicotine concentration)., Conclusions: Accurate assessment of ENDS products proved challenging, but cognitive interviews provided valuable insight into survey interpretation that was otherwise inaccessible to researchers. Future research that explores how to assess the wide array of ENDS devices, as well as possible population differences among specific device-type users would be valuable to public health researchers and professionals., Implications: This study extends the current literature by using cognitive interviews to test ENDS assessment questions in a sample of young adults, a population at elevated risk for ENDS use. Problems encountered when answering ENDS use questions underscore the need to develop easily understood ENDS questions that allow for quantification of ENDS use. Future research examining the nature of ENDS product types and different levels of user experience will yield valuable assessment tools for researchers and tobacco control professionals., (© The Author 2016.
