Correlates of susceptibility to waterpipe tobacco smoking in young adults.

INTRODUCTION: Many US young adults are susceptible to waterpipe (i.e., hookah) tobacco smoking (WTS) initiation, but research on factors associated with WTS susceptibility is limited. We examined sociodemographic, other tobacco and substance use, and attitudes and perceptions correlates of WTS susceptibility among young adults. METHODS: Baseline data from a randomized trial testing WTS risk messages was collected in US young adults aged 18 to 30 years who never used waterpipe tobacco but were susceptible to WTS (n = 294). Extent of susceptibility to WTS was defined using the average score of a valid scale with higher scores indicating higher susceptibility. Correlates were sociodemographics, other tobacco and substance use, and attitudes and perceptions. Multiple linear regression models identified correlates of greater WTS susceptibility. RESULTS: Participants averaged 25 (SD 3.2) years of age, 60% were male, 22% were Black non-Hispanic, 47% completed some college education, and 66% were employed. Our models consistently showed that more positive attitudes toward WTS (ß = -0.08, p<0.01), lower perceived addictiveness relative to cigarettes (ß = -0.09, p = 0.04), and greater perceived social acceptability of WTS (ß = 0.05, p<0.01) were positively correlated with WTS susceptibility. Additionally, young adults who smoked cigarillos (ß = 0.53, p<0.01), used cannabis (ß = 0.14, p = 0.02), and Black non-Hispanic versus White non-Hispanic young adults (ß = 0.18, p = 0.03) also had higher WTS susceptibility. CONCLUSIONS: Findings suggest that WTS prevention efforts require multicomponent interventions including targeting subpopulations at greater risk based on race/ethnicity and other tobacco and substance use. These interventions should consider attitudes and social acceptability of WTS as modifiable targets to maximize public health benefits.

Associations Between Noticing E-Cigarette Advertising Features and E-Cigarette Appeal and Switching Interest Among Young Adult Dual Users.

BACKGROUND: E-cigarette advertising, which often includes various features, may prompt e-cigarette use and product switching. This study examined the associations between noticing e-cigarette ad features and perceived product appeal and interest in completely switching from cigarettes to advertised e-cigarettes among young adult dual users of both products. METHODS: We analyzed data from an online heatmap experiment among young adult dual users defined as established cigarette smokers who currently used e-cigarettes (ages 18-34 years; n = 1,821). Participants viewed 12 e-cigarette ads, clicked on ad features (e.g., fruit flavors, nicotine warnings, price promotions, smoker-targeted claims) that attracted their attention (defined as "noticing"), and answered questions about e-cigarette product appeal and interest in completely switching from cigarettes to the e-cigarettes shown. We examined within-person associations between noticing specific ad features and outcomes, controlling for demographic and tobacco use-related characteristics. RESULTS: Noticing fruit flavors (AOR = 1.67 and 1.28) and fruit images (AOR = 1.53 and 1.21) was positively associated with having any e-cigarette product appeal and switching interest. Noticing price promotions (AOR = 1.23) was positively associated with product appeal. In contrast, noticing nicotine warnings (AOR = 0.74 and 0.86), smoker-targeted claims (AOR = 0.78 and 0.89), and tobacco flavors (AOR = 0.92 and 0.90) was negatively associated with product appeal and switching interest. CONCLUSIONS: Noticing certain e-cigarette ad features (e.g., fruit flavors and nicotine warnings) may be associated with product appeal and/or switching interest among young adult dual users. More research is needed to assess the influence of e-cigarette ad features that promote product switching interests among cigarette smokers while discourage interests among tobacco-naïve individuals.

Associations of educational and marketing messages with beliefs about nicotine and reduced nicotine cigarettes.

INTRODUCTION: Widespread misperceptions about nicotine may have unintended effects on public health. We examined associations between existing messages about nicotine or tobacco and beliefs about nicotine and reduced nicotine cigarettes (RNC). METHODS: 2962 U.S. 18-45-year-olds were randomized in a May 2022 web-based survey to view one of 26 text-based messages about tobacco or nicotine from three sources: ongoing research (n = 8), messages authorized by FDA for VLN cigarettes (n = 6), and FDA's "From Plant to Product to Puff" campaign (n = 12); six messages from FDA's campaign did not reference nicotine and were treated as the reference source. Analyses examined associations between messages, grouped by source and individually, with beliefs about nicotine and RNC addictiveness and harms. RESULTS: Relative to FDA messages that did not reference nicotine, all message sources were associated with greater odds of a correct belief about nicotine (Odds Ratios [ORs] = 1.40-1.87, p's < 0.01); VLN messages were associated with greater correct beliefs about RNC addictiveness (b = 0.23, p < .05). No campaign produced greater correct beliefs about RNC harms. At the individual level, only five messages were associated with a correct belief about nicotine (ORs = 2.12-2.56, p-values < .01), and one with correct beliefs about RNC harms (b = 1.09, p < .05), vs. the reference message. CONCLUSIONS: Few existing messages improved understanding of the risks of nicotine separately from the risks of combustible products. Communication research is needed to promote greater public understanding of nicotine while minimizing unintended effects on nicotine and tobacco use.

"I don't think that a medication is going to help someone long-term stay off opioids": Treatment and recovery beliefs of rural Vermont family members of people with opioid use disorder.

PURPOSE: Few studies have addressed beliefs about treatment for opioid use disorder (OUD) among family members of people with OUD, particularly in rural communities. This study examined the beliefs of rural family members of people with OUD regarding treatment, including medication for OUD (MOUD), and recovery. METHODS: Semi-structured qualitative interviews were conducted with rural Vermont family members of people with OUD. Twenty family members completed interviews, and data were analyzed using thematic analysis. RESULTS: Four primary themes related to beliefs about OUD treatment emerged: (1) MOUD is another form of addiction or dependency and should be used short-term; (2) essential OUD treatment components include residential and mental health services and a strong support network involving family; (3) readiness as a precursor to OUD treatment initiation; and (4) stigma as an impediment to OUD treatment and other health care services. CONCLUSIONS: Rural family members valued mental health services and residential OUD treatment programs while raising concerns about MOUD and stigma in health care and the community. Several themes (e.g., MOUD as another form of addiction, residential treatment, and treatment readiness) were consistent with prior research. The belief that MOUD use should be short-term was inconsistent with the belief that OUD is a disease. Findings suggest a need for improved education on the effectiveness of MOUD for family members and on stigma for health care providers and community members.

Measuring disability among U.S. adolescents and young adults: A survey measurement experiment.

Objective: Disability is identified in surveys using various question sets, with little understanding of reliability across these measures, nor how these estimates may vary across age groups, including adolescents and young adults (AYA). The purpose of this study was to assess AYA prevalence of disability using two disability question sets and reliability of these measures. Methods: AYA participants in the Policy and Communication Evaluation (PACE) Vermont Study completed a single-item disability question used in the National Survey on Health and Disability (NSHD) and Urban Institute's Health Reform Monitoring Survey (HRMS) and a six-item set on functioning (Washington Group-Short Set, WG-SS) from the National Health Interview Survey (NHIS) and National Survey on Drug Use and Health (NSDUH) in 2021. Prevalence was estimated for any disability and each disability domain in adolescents (ages 12-17) and young adults (ages 18-25) and compared with U.S. national estimates in NHIS and NSDUH. Results: Using the WG-SS, the prevalence of any disability was 17.0 % in PACE Vermont adolescents and 22.0 % in young adults, consistent with the national prevalence of adolescents in NSDUH (17.9 %) but higher than estimates of young adults in NHIS (3.9 %) and NSDUH (12.9 %). The single-item question provided lower estimates of disability (adolescents: 6.9 %; young adults: 18.5 %) than the WG-SS, with low positive agreement between measures. Discussion: The prevalence of disability in AYAs varies depending on measures used. To improve disability surveillance, it may be necessary to validate new disability questions, including among AYAs, to capture a broader range of disability domains.

Longitudinal association between harm perceptions and tobacco behaviors among adults who smoke cigarettes: Differential associations across age groups using the PATH study.

INTRODUCTION: The relationship between e-cigarette and cigarette harm perceptions and tobacco behaviors may vary by age. We examined longitudinal associations of harm perceptions with tobacco use behaviors among adults who smoke cigarettes. METHODS: Data were from Waves 4 (2016-2018) and 5 (2018-2019) of the Population Assessment of Tobacco and Health survey. Weighted multivariable logistic regressions identified independent associations between relative and absolute e-cigarette and cigarette harm perceptions at baseline and continued smoking, dual use, complete switching, and quit intention at follow-up, stratified by age (young adults [YAs] 18-24, middle-aged adults [MAs] 25-44, and older adults [OAs] ≥45) among U.S. adults who smoke (n=8,231). RESULTS: Perceiving e-cigarettes as less harmful than cigarettes was associated with higher odds of complete switching from cigarettes to e-cigarettes (aORs overall: 1.52; MAs: 1.68). Perceiving e-cigarettes as very/extremely harmful was associated with lower odds of dual use (overall aOR: 0.75; MAs: 0.72) and higher odds of quit intention (aOR among OAs: 1.34). Perceiving cigarettes as very/extremely harmful was associated with lower odds of continued smoking (overall aOR: 0.69; MAs: 0.76; OAs: 0.53), and higher odds of complete switching (overall aOR: 1.65; MAs: 1.86) and quit intention (overall aOR: 1.58; MAs: 1.42; OAs: 1.80). No findings reached significance for YAs. DISCUSSION: E-cigarette relative and absolute harm perceptions were associated with different tobacco behaviors by age. Low cigarette harm perceptions were similarly associated with continued smoking and lower quit intentions in MAs and OAs. Future research should explore what beliefs inform these perceptions and age-related differences. IMPLICATIONS: The associations between harm perceptions and subsequent tobacco behaviors differed by age among adults who smoke. This study adds that low relative harm perceptions of e-cigarettes can promote complete switching among MAs who smoke. High absolute harm perceptions of e-cigarettes may deter dual use among MAs. Additionally, high absolute harm perceptions of cigarettes may reduce smoking and increase cigarette smoking quit intentions among MAs and OAs. Future research is needed to understand the beliefs that support harm perceptions among different age groups and why their effects differ by age, and what factors influence YAs' tobacco use behaviors.

Widespread Misperceptions Among U.S. Adults About Tobacco Company Engagement in Black and African American Communities.

INTRODUCTION: Menthol cigarettes and flavored cigars (MC/FC) bring profits to U.S. tobacco companies at the cost of Black/African American (B/AA) lives. This exploratory cross-sectional study describes perceptions of tobacco company engagement and activities in B/AA communities related to MC/FC. AIMS AND METHODS: Among 2307 U.S. adults aged 18-45 surveyed in 2022, six items addressed beliefs about tobacco company funding of B/AA community organizations, payment of B/AA lobbyists to oppose public health policies, support of health equity efforts in B/AA communities, and targeted marketing of MC/FC in B/AA communities. Adjusted proportions were calculated for each belief overall and by race and cigarette smoking status. RESULTS: Among all adults, 37% believed that tobacco companies deny the harms of MC/FCs, 20% believed they pay Black lobbyists to oppose health policies, and 12% believed they fund Black community organizations. Compared with non-B/AA adults, a higher proportion of B/AA adults believed that tobacco companies target Black communities with MC/FC marketing (62% vs. 46%). More adult smokers (ie, menthol or non-MC) than nonsmokers thought that tobacco companies support health equity efforts and did not target Black communities with MC/FC marketing nor deny the harms of MC/FCs to B/AA communities. CONCLUSIONS: Few B/AAs and adult smokers believed that tobacco companies used B/AA organizations and lobbyists to oppose MC/FC policies in the B/AA community as well as reject MC/FC's harmfulness. Culturally tailored and community-engaged communication efforts are needed to correct disinformation about MC/FC tobacco companies' engagement and activities in B/AA communities among B/AA and menthol cigarette smokers. IMPLICATIONS: Tobacco companies have a history of predatory marketing that promotes flavored tobacco products to Black/African American (B/AA) individuals and more recently has spread disinformation to dissuade policy support for menthol cigarette/flavored cigar (MC/FC) bans. It is unclear what are the perceptions of tobacco company engagement and activities in B/AA communities related to MC/FC. Our study shows that B/AA adults and current cigarette smokers hold misperceptions about tobacco companies' role in spreading disinformation about MC/FC. This study identified beliefs about the industry's role in funding B/AA organizations and lobbyists who oppose policy, as well as the industry's denial of menthol cigarette and flavored cigar harms as potential messaging targets for communication efforts designed to correct disinformation about MC/FC policies among B/AA and those who currently smoke MC.

Examining the predictive utility of behavioral economic demand indices and subjective effects on the actualized reinforcing value of menthol cigarettes and potential alternatives.

INTRODUCTION: Considering recent and proposed bans on menthol cigarettes, methods are needed to understand the substitutability of potential menthol cigarette alternatives (MCAs) for menthol cigarettes. This study examined the prospective relationship between behavioral economic demand indices and subjective effects of usual brand menthol cigarettes (UBMC) and preferred MCAs with subsequent performance on a laboratory-based concurrent-choice task comparing UBMC and MCAs. METHODS: Eighty participants who typically smoked menthol cigarettes completed this clinical lab study. After sampling each product, participants completed the cigarette purchase task (CPT) and modified cigarette evaluation questionnaire (mCEQ). Following one-week of substituting their preferred MCA for their UBMC, participants completed a 90-min concurrent-choice self-administration task comparing their UBMC and preferred MCA. Linear regression models explored associations between CPT demand indices and mCEQ subjective effects in the lab with subsequent response effort for UBMCs on the concurrent-choice task. RESULTS: Three demand indices for UBMC were positively associated with UBMC response effort: Essential Value (EV; p=.02), Omax (p=.02), and breakpoint (p=.04). Four CPT demand indices for the preferred MCA significantly corresponded with UBMC response effort: EV (p=.03), Pmax (p=.04), Omax (p=.03), and breakpoint (p=.03). Subjective effects captured by the mCEQ were not associated with response effort. CONCLUSIONS: Demand indices reflecting Persistence (i.e., sensitivity to escalating price) predicted effort to obtain UBMC puffs on the concurrent-choice task. Among this sample, the CPT captured information on the relative reinforcing value (i.e., addiction potential) of combustible tobacco products similar to the longer self-administration task. IMPLICATIONS: In an ever-changing product market, assessing the reinforcing efficacy of menthol cigarettes and putative substitutes quickly and with validity is an important methodological tool for understanding abuse liability. Results suggest that behavioral economic demand indices of cigarette purchase task efficiently capture information on the relative reinforcing value of usual brand menthol cigarettes and plausible alternative tobacco products, similar to a 90-min in-laboratory self-administration task.

Cigarette smoking behaviors and nicotine dependence at the intersection of sexual identity and sex in the United States: Findings from the National Survey on Drug Use and Health.

INTRODUCTION: Cigarette smoking is disproportionately high among lesbian, gay, and bisexual (LGB) adults. Yet, collapsing these identities into a monolith can disguise important within group disparities (e.g., lesbian/gay versus bisexual female). The purpose of this study is to report recent national prevalence estimates and trends of cigarette smoking behaviors and nicotine dependence by sexual identity and sex. METHODS: Data were from the 2015-2019 National Survey on Drug Use and Health (n = 210,392; adults 18+), a nationally representative, repeated cross-sectional study of substance use and mental health in the U.S. We examined bivariate and multivariable associations between sexual identity and cigarette smoking measures (i.e., former smoking, lifetime smoking, current smoking, current daily smoking, nicotine dependence) by sex. We also examined linear time trends in current and former smoking. Covariates included age, race/ethnicity, education, annual household income, and survey year. RESULTS: Bisexual women had the highest unadjusted prevalence of current smoking (31 %) and lowest of former smoking (25 %). LGB females and males had higher adjusted prevalence of current smoking, daily smoking, and nicotine dependence than heterosexual adults. Bisexual females and gay and bisexual males had lower adjusted prevalence of former smoking (adjusted prevalence ratio range: 0.78-0.85) than heterosexual counterparts. DISCUSSION: This is the first study to identify disproportionately low prevalence of former smoking among bisexual females. Paired with findings of high prevalence of current cigarette smoking and nicotine dependence, these data suggest that tobacco control interventions targeted toward bisexual females are urgently needed to reduce the burden of cigarette smoking among these individuals.

Implementation of Quitline Financial Incentives to Increase Counseling Sessions Among Adults Who Use Menthol Tobacco Products.

Since 2017, the Vermont Tobacco Control Program (VTCP) has worked to reduce the impact of flavored tobacco products on Vermonters. With the proposed U.S. Food and Drug Administration (FDA) rules banning menthol cigarettes and flavored cigars and proposed legislation banning sales of all menthol and flavored tobacco products in Vermont, VTCP prioritized resources to support cessation among Vermonters who use menthol tobacco products. In March 2021, VTCP began offering a tailored quitline protocol for adults who use menthol tobacco, including financial incentives, for completed coaching sessions. From March 2021 to May 2022, 66 quitline callers enrolled in the menthol incentive protocol, representing 8% of all quitline callers and 25% of participants in the state's quitline incentive programs. A greater proportion of callers in the menthol incentive program completed three or more quitline calls (58% vs. 38%) and enrolled in phone and text support (61% vs. 32%). Quitline callers enrolled in any incentive protocols (menthol, Medicaid/uninsured, or pregnant) were more likely to request one or two forms of nicotine replacement therapy (NRT). Quitlines remain an effective, evidence-based method of tobacco cessation, especially in reaching vulnerable populations. Given the targeted marketing of menthol brands to Black and African American populations, LGBTQ+ populations, youth, and neighborhoods with lower incomes, addressing menthol cigarette use is key to improving health equity and health of Vermonters. Early data indicates that the use of financial incentives can increase engagement with a state quitline among menthol tobacco users through greater completion of cessation coaching calls, enrollment in text message support, and NRT usage.

Patterns of Alcohol, Marijuana, and Tobacco Use Among U.S. Adolescents and Young Adults by Disability Status: 2015-2019.

PURPOSE: To estimate the national prevalence of tobacco, marijuana, and alcohol use among U.S. adolescents (age 12-17) and young adults (aged 18-25; adolescents and young adults [AYAs]) with a disability and examine associations between disability and substance use from 2015 to 2019. METHODS: Data from the 2015-2019 National Survey on Drug Use and Health were used to estimate the prevalence of tobacco, marijuana, and alcohol use among AYAs with disabilities. Modified Poisson regression models evaluated linear time trends in past-month substance use and estimated adjusted prevalence ratios (aPRs) for past-month cigarette, any tobacco, alcohol, and marijuana use. RESULTS: Adolescents with any disability had a higher prevalence of past-month cigarette (aPR = 1.87; 95% CI 1.67-2.09), alcohol (aPR = 1.21; 95% CI 1.11-1.31), and marijuana use (aPR = 1.47; 95% CI 1.36-1.60) compared to those without disabilities. Cigarette smoking among adolescents decreased over this time period; however, the decline among adolescents without a disability was greater than those with any disability. Young adults with any disability had a higher prevalence of past-month cigarette (aPR = 1.42; 95% CI 1.35-1.48) and marijuana use (aPR = 1.39; 95% CI 1.34-1.45), but a lower prevalence of past-month alcohol use (aPR = 0.93; 95% CI 0.90-0.95) than those without disabilities. Alcohol use remained constant among young adults with any disability but decreased for those without disabilities. DISCUSSION: Population-level disparities in cigarette and marijuana use exist in AYAs with disabilities. Future studies should identify strategies tailored to AYAs with disabilities to encourage smoking cessation and prevent cannabis use disorder.

Smoking cessation interventions for U.S. adults with disabilities: A systematic review.

INTRODUCTION: People with disabilities disproportionately use tobacco products. However, little is known about cessation interventions tailored for people with disabilities. The objective of this study was to conduct a systematic review of smoking cessation interventions for adults with disabilities. METHODS: Six electronic databases (Cochrane, CINAHL Plus [EBSCOhost], Embase [Ovid], Medline [Ovid], PsycINFO [Ovid], and Web of Science) were searched to identify eligible interventions for people with disabilities (e.g., vision, hearing, mobility, communication, cognition, self-care) through July 2023. Two independent coders evaluated the records and extracted data from studies that met inclusion criteria. Qualitative synthesis was conducted on the included studies in 2023. RESULTS: One randomized controlled trial and one nonrandomized study met the inclusion criteria. Both studies used mindfulness-based procedures to reduce cigarette use in adults with mild intellectual disability. The outcome was defined as self-reported cigarette use at follow-up, which ranged from 1 year to 3 years. Limited information was provided on how the interventions were tailored to meet the unique needs of people with disabilities in either study. CONCLUSION: Two interventions conducted in adults with mild intellectual disability showed promising results using mindfulness-based procedures; however, the studies did not address barriers reported by people with disabilities, nor tailor the interventions to meet the needs of the target population. Research is needed to address tobacco use disparities among people with a range of disabilities. Current cessation interventions would be enhanced by integrating disability identifiers alongside other demographic information in future studies and reporting subgroup analyses in adults with disabilities.

Substitutability of menthol cigarette alternatives: a clinical trial.

INTRODUCTION: This study assessed the substitutability of plausible combustible menthol cigarette alternatives (MCAs) for usual brand menthol cigarettes (UBMCs) in adults who smoke menthol cigarettes. METHODS: Following three in-lab sampling sessions, 80 adults aged 21-50 who smoke menthol cigarettes chose their preferred MCA: (1) a menthol roll-your-own cigarette (mRYO), (2) a menthol filtered little cigar (mFLC) or (3) a non-menthol cigarette (NMC). Participants were instructed to completely substitute their preferred MCA for their UBMC for 1 week and complete daily diaries documenting adherence and subjective effects. At the final lab visit, participants completed concurrent choice and cross-price elasticity tasks with their substitute product and UBMC as the comparator. RESULTS: Most (65%) participants chose mRYO as their preferred product, followed by NMC and mFLC. Adherence to MCA was high for all products across the week (range: 63%-88%). Positive subjective effects for mRYO decreased over time but remained numerically higher than the other MCA products; craving reduction also decreased for NMC across phases. In the progressive ratio task, participants chose their UBMC in 61.7% of choices; this did not differ by preferred MCA, although the median breakpoint was highest for mRYO and similar for mFLC and NMC. Cross-price elasticity comparing UBMC and the preferred product indicated high substitutability of each MCA at phase 3 (I values -0.70 to -0.82). CONCLUSIONS AND RELEVANCE: mRYOs were the most preferred MCA among the study products, but all MCAs were acceptable substitutes for UBMC using behavioural and economic measures in a short-term trial period.Trial registration number NCT04844762.

Statewide Trends in Buprenorphine Prescribing in Rural and Nonrural Vermont: Analysis of Population-based Patient Pharmacy Claims.

IMPORTANCE: Opioid-related mortality rates have risen dramatically over the past decade, and office-based opioid treatment using buprenorphine offers hope for combatting this trend. Vermont's policymakers, health care systems, and treatment providers have worked to expand access to treatment throughout the rural state. OBJECTIVE: The objective of the current study was to characterize the trends in the number of buprenorphine prescribers and the number of patients per prescriber in Vermont over the past decade (2010-2020). METHODS: We used Vermont's all-payer claims database to identify patients with buprenorphine claims between 2010 and 2020 and their prescribers. We conducted analyses of trends in the number of prescribers treating different numbers of patients, the number of patients treated by prescribers in those categories, and the number of rural (vs nonrural) patients filling buprenorphine prescriptions. We used Z tests to determine if there were statistical differences between trends. RESULTS: The number of buprenorphine prescribers treating 10+ patients grew more rapidly than other prescriber groups ( P < 0.001). Nearly half of Vermont patients in 2020 were treated by 33 high-volume prescribers who treated 100 or more patients with buprenorphine. The number of patients filling buprenorphine prescriptions in Vermont increased by 98% between 2010 and 2020, with greater increases seen among rural than nonrural residents (107% vs 72%; P = 0.008). CONCLUSIONS AND RELEVANCE: Since 2010, Vermont has increased utilization of its office-based opioid treatment capacity, particularly in rural counties.

Effect of nicotine corrective messaging on nicotine-related beliefs in US adults: a randomised controlled trial.

INTRODUCTION: Widespread misperceptions of the health risks of nicotine could undermine the public health benefits of the Food and Drug Administration's actions, including modified risk tobacco product authorisations and a reduced nicotine product standard for cigarettes. METHODS: 794 US adults (aged 18+) in NORC's AmeriSpeak panel participated in a randomised controlled trial in Spring 2021 to test the effect of three exposures to eight nicotine corrective messages (NCM) on beliefs about nicotine, nicotine replacement therapy (NRT), e-cigarettes and reduced nicotine content (RNC) cigarettes at 3-month follow-up. Analyses conducted in 2022 examined the effect of study condition (NCM (n=393) vs no message control (n=401)) on nicotine beliefs, use intentions and use of nicotine and tobacco products. RESULTS: Exposure to three NCM doses reduced nicotine (b=-0.33; 95% CI -0.60, -0.07), NRT (b=-0.49; 95% CI -0.85, -0.14), e-cigarette (b=-0.32; 95% CI -0.59, -0.05) and RNC cigarette false beliefs (b=-0.64; 95% CI -1.26, -0.02) compared with the control, controlling for baseline beliefs. Baseline tobacco use and concern about nicotine addiction attenuated intervention effects on false beliefs about RNC cigarettes. There were few intervention effects on intention or use of nicotine and tobacco products. CONCLUSIONS: Repeated exposure to NCM was necessary to reduce false beliefs about nicotine and tobacco products. Future studies will improve understanding of the dose and duration of nicotine education needed to shift intentions and behaviour, as well as tailored content for tobacco product users to achieve similar reductions in false beliefs as non-users. TRIAL REGISTRATION NUMBER: NCT04805515.

Effects of cigarette package colors and warning labels on marlboro smokers' risk beliefs, product appraisals, and smoking behavior: a randomized trial.

OBJECTIVE: Plain packaging and graphic warning labels are two regulatory strategies that may impact cigarette risk beliefs and reduce consumption, but data are needed to better understand how smokers respond to such regulations. METHODS: Adult, daily, Marlboro non-menthol smokers (Red [n = 141] or Gold [n = 43]) completed a mixed factorial randomized trial. Participants smoked their usual cigarettes during baseline (5-days) and were randomized to receive cigarette packs with a warning label manipulation (graphic vs. text-only). Within each warning label condition, participants completed three within-subjects pack color manipulations (red, gold, plain), each lasting 15 days. Participants were blinded to the fact that all packs contained their usual cigarettes. Mixed-effects models examined between- and within-subject differences on risk beliefs, product perceptions, and smoking behavior. RESULTS: Warning type and package color did not impact cigarette consumption or subjective ratings. However, use increased in all conditions (2.59-3.59 cigarettes per day) relative to baseline. While smokers largely held correct risk beliefs at baseline (Mean = 6.02, SE = 0.17, Range:0-8), the cumulative number of incorrect or uncertain cigarette risk beliefs increased from baseline in all pack color manipulations in the text (IRR range = 1.70-2.16) and graphic (IRR range = 1.31-1.70) warning conditions. Across all pack color periods, those in the graphic (vs. text) warning condition had reduced odds of reporting their study cigarettes as 'safer' than regular cigarettes (OR range = 0.22-0.32). CONCLUSIONS: Pack color modification may increase uncertainty about several key cigarette risk beliefs, though graphic warnings may attenuate these effects. Regulatory agencies could consider supporting policy changes with information campaigns to maximize public knowledge. TRIAL REGISTRATION: November 25, 2014; Registration number: NCT02301351.

Dramatic Reductions in Cigarette Smoking Prevalence among High School Youth from 1991 to 2022 Unlikely to Have Been Undermined by E-Cigarettes.

There is concern that youth e-cigarette use could lead youth to initiate cigarette smoking. This study identifies epochs of cigarette smoking among U.S. high school students in three commonly utilized national school-based surveys over three decades without a priori assumptions. We examined trends in ever and current cigarette smoking among high school youth from 1991 to 2022 in three datasets: Monitoring the Future (MTF), the National Youth Risk Behavior Survey (NYRBS) and the National Youth Tobacco Survey (NYTS) via Joinpoint regression. High stable rates of ever smoking were noted from 1991 to 1999 (NYRBS and MTF) and then significantly declined from 1999 to 2013; declines accelerated through to 2022. In the NYTS, ever cigarette smoking significantly declined from 1999 to 2018 and then declines accelerated to 2022. Current cigarette smoking reached its peak in 1997, and then significantly declined from 1997 to 2013 in the NYRBS and MTF and similarly in the NYTS from 1999 to 2018. Declines in current smoking then accelerated in all surveys through to 2022. These findings suggest dramatic successes in reducing youth smoking since the late 1990s, with more rapid declines in prevalence in the past decade.

Effects of pictorial warning labels depicting lesser-known and well-known risks of smoking on viewing patterns, recall, and knowledge of smoking harms.

BACKGROUND: In 2019, the Food and Drug Administration introduced 11 pictorial warning labels (PWLs) for inclusion on cigarette packages, created in compliance with court recommendations and tailored to increase knowledge of smoking harms. Several highlighted lesser-known risks of smoking. No behavioral studies have yet evaluated how risk content in PWLs impacts viewing patterns, recall, and knowledge of smoking harms. METHODS: Seventy adults who reported smoking cigarettes daily (62.9% male, 57.1% African American, mean age = 50.3, mean cigarettes per day = 14.4) completed a single-session laboratory study. They were randomized to view a set of four PWLs depicting either lesser-known or well-known risks of smoking while having eye movements recorded, then completed post-exposure recall and knowledge measures. RESULTS: Participants exposed to PWLs depicting lesser-known smoking risks viewed the text of the warning sooner and for longer than the image (p's <0.05); those exposed to PWLs depicting well-known risks viewed the image longer than text (p <0.001). PWL condition did not affect recall of text or image (p's >0.1). Those viewing lesser-known (vs. well-known) risks had greater knowledge of smoking causing lesser-known risks of bladder cancer, blindness, bloody urine, cataracts, diabetes, and head and neck cancer (p's <0.001). CONCLUSIONS: Individuals viewing PWLs depicting lesser-known (vs. well-known) smoking risks visually engaged with the PWL text more than image, had similarly high recall of PWL content, and had greater knowledge of lesser-known risks of smoking. Findings suggest including lesser-known risk information on PWLs improves overall knowledge of smoking health risks.

Effects of reduced nicotine content cigarette advertising with warning labels and social media features on product perceptions among young adults.

This study sought to understand reactions to very low nicotine (VLN) cigarette advertising compared with conventional cigarette advertising with consideration of warning labels and social media context. The online experimental study recruited young adult cigarette smokers and nonsmokers (N = 1,608). Participants completed a discrete choice task with a 2 × 2 × 3 mixed design: brand, (VLN, Marlboro), context (Ad only, Ad on social media), and warning (Text-only, Well-known risk pictorial, or Lesser-known risk pictorial). Participants made choices about attention, appeal, harm, buying, and quitting intentions. Social media context increased attention and appeal. A well-known risk pictorial warning outperformed a text-only warning. Smokers had increased odds of quit intentions for VLN ads, yet nonsmokers had increased intentions to buy cigarettes on social media with a text-only warning. Results indicate differences in how young adults react to cigarette ads on social media, especially with the warnings they portray.
