Quantity of cigarettes smoked when co-used with alcohol and cannabis: Consideration of different definitions of co-use based on daily diary data.

INTRODUCTION: Cigarettes are frequently co-used with alcohol and cannabis. However, definitions of co-use vary and the extent to which cigarette use changes on days with different patterns of co-use is unclear. We compared the number of cigarettes smoked on different days based on co-use patterns of cigarettes and alcohol or cannabis. METHODS: This study analyzed 2408 smoking days collected in a 30-day smartphone-based daily diary study among 146 young adults (aged 18-26) with an oversample from sexual minority groups. Two separate multilevel models were estimated: one for cigarette and alcohol co-use and the other for cigarette and cannabis co-use. Both models examined day-level associations between the number of cigarettes smoked and 3 different types of days (smoking-only days, same-occasion co-use days, different-occasion co-use days), controlling for demographic characteristics. RESULTS: More cigarettes were smoked on same-occasion co-use days compared to cigarette-smoking-only days for both alcohol (b=1.474, SE=0.136, t=10.8, p<.001) and cannabis (b=0.822, SE=0.209, t=3.9, p<.001). There were no significant differences in cigarettes smoked on days with co-use on the same day, but on different occasions, compared to days with smoking only. CONCLUSIONS: Compared to days with cigarette smoking only, more cigarettes are smoked on days when cigarettes are co-used with alcohol or cannabis on the same occasion, while the same is not true for days with co-use on different occasions. Conflating different definitions of co-use may impact findings on associations between co-use and smoking behavior.

Oral nicotine product marketing expenditures in the USA from 2016 to 2023: trends over time by brand and targeted media outlets.

BACKGROUND: Oral nicotine products (ONPs) are increasing in sales, availability and flavours. In April 2022, the US Food and Drug Administration (FDA) obtained regulatory authority over non-tobacco nicotine products, which include many ONPs. Advertising practices for ONPs need monitoring to understand marketing strategies and inform FDA marketing authorisation decisions. METHODS: ONP advertisement (ad) expenditure data (January 2016-June 2023) were purchased (print, TV, radio, online video, online display and mobile; N=125 236) and adjusted to 2023 dollars. Descriptive statistics examined expenditures by ONP brand and media outlet over time. RESULTS: Velo spent the most on ONP advertising (89.8%), followed by Zyn (5.7%) and Black Buffalo (1.2%). Velo encompassed the majority of TV (98.1%), radio (99.9%) and mobile ad spend (87.3%); Zyn was the leader for online display (46.2%) and online video (71.1%); and Black Buffalo accounted for 100% of print ads. In 2023, (January-June), Zyn accounted for 88.0% of ad expenditures and Velo spent $0, though the total amount spent by Zyn was far less than Velo in prior years. TV ads (98.1% Velo) aired primarily on prime time/late night or 09:00-17:00 on weekends. Radio ads (99.9% Velo) aired primarily from 06:00 to 10:00, 12:00 to 14:00 and 15:00 to 19:00 on weekdays. Overall, expenditures focused on reaching a national audience, though print ads indicated potential male-targeted marketing. CONCLUSIONS: Following FDA's regulatory authority over non-tobacco nicotine products, ad expenditures for Velo dropped to $0. Ongoing surveillance of ONP ad trends can inform FDA marketing authorisation decisions by revealing brand-specific marketing strategies that may be targeted toward populations at increased risk of tobacco use.

Pharmaceuticalisation as the tobacco industry's endgame.

CONTEXT: Declining smoking prevalence and denormalisation of tobacco in developed countries reduced transnational tobacco company (TTC) profit during 1990s and 2000s. As these companies faced increasingly restrictive policies and lawsuits, they planned to shift their business to socially acceptable reduced-harm products. We describe the internal motivations and strategies to achieve this goal. METHODS: We analysed previously secret tobacco industry documents available through the Truth Tobacco Documents Library. These documents were triangulated with TTCs' investor and other professional reports, websites and public statements. FINDINGS: Mimicking pharmaceutical business models, tobacco companies sought to refurbish their image and ensure long-term profitability by creating and selling pharmaceutical-like products as smoking declined. These products included snus, heated tobacco products, e-cigarettes, nicotine gums and inhalers. Tobacco companies created separate divisions to develop and roll out these products, and the majority developed medical research programmes to steer these products through regulatory agencies, seeking certification as reduced-harm or pharmaceutical products. These products were regarded as key to the survival of the tobacco industry in an unfriendly political and social climate. CONCLUSIONS: Pharmaceuticalisation was pursued to perpetuate the profitability of tobacco and nicotine for tobacco companies, not as a sincere search to mitigate the harms of smoking in society. Promotion of new pharmaceuticalised products has split the tobacco control community, with some public health professionals and institutions advocating for the use of 'clean' reduced-harm nicotine and tobacco products, essentially carrying out tobacco industry objectives.

Factors Associated With Abstinence Among Young Adult Smokers Enrolled in a Real-world Social Media Smoking Cessation Program.

OBJECTIVE: Social media platforms are promising to provide smoking cessation support. This study aimed to identify baseline factors associated with cigarette smoking abstinence among young adult smokers enrolled in a real-world social media-based smoking cessation program. AIMS AND METHODS: We analyzed data from young adult smokers (aged 18-30 years) participating in a publicly available Facebook-based smoking cessation program serving the San Francisco Bay Area. The analytic sample consisted of 248 participants who completed both the baseline and follow-up surveys at 3 months. Multivariable logistic regression analysis determined baseline factors significantly associated with self-reported 7-day cigarette smoking abstinence at 3 months. RESULTS: Participants were race/ethnically diverse, well-educated, and 47.6% reported LGB + sexual identity. Those who reported dual use of cigarettes and e-cigarettes in the past 30 days (vs. cigarette use only), current alcohol users (vs. non-users), and those aged 25-30 years (vs. 18-24 years) were significantly less likely to report 7-day abstinence at 3 months. Non-daily smokers (vs. daily smokers) and those with high desire to quit smoking (vs. low to moderate desire) were more likely to report abstinence. Results also showed reduction in the percentage of e-cigarette and other tobacco product use among participants. CONCLUSIONS: Social media interventions may be more effective for young adult non-daily smokers and those with high desire to quit smoking. Smoking cessation programs may help reduce use of other tobacco products among treatment-seeking smokers. Smoking cessation interventions for young adults need to explicitly address dual use of cigarettes and e-cigarettes and use of alcohol. IMPLICATIONS: Findings of this study highlight the need for future interventions to address dual use of cigarettes and e-cigarettes and use of alcohol to improve cigarette smoking abstinence outcomes. The reduction in the use of other tobacco products among program participants indicates that social media smoking cessation programs may exert a broader positive influence on overall tobacco consumption. The large number of LGB+ smokers participating in the program suggests social media is a promising cessation channel for this hard-to-reach group, warranting further study.

Classification of patterns of tobacco and cannabis co-use based on temporal proximity: A qualitative study among young adults.

PURPOSE: Co-use of tobacco and cannabis is a common and complex behavior. The lack of harmonized measures of co-use yields confusion and inconsistencies in synthesizing evidence about the health effects of co-use. We aimed to classify co-use patterns based on temporal proximity and describe preferred products and motives for each pattern in order to improve co-use surveillance. METHODS: We conducted semi-structured interviews in a sample of 34 young adults (Mage = 22.8 years, 32.4 % female) during 2017-2019 in California, USA. We employed a qualitative thematic analysis to identify timing, reasons, and contexts for tobacco and cannabis co-use and classify co-use patterns. RESULTS: Four emergent patterns of co-use with increasing temporal proximity between tobacco use and cannabis use were: Same-month different-day co-use (Pattern 1); Same-day different-occasion co-use (Pattern 2); Same-occasion sequential co-use (Pattern 3); and Same-occasion simultaneous co-use (Pattern 4). Participants used various product combinations within each pattern. Similar motives for all patterns were socialization, product availability, and coping with stress/anxiety. Unique motive for temporally distant patterns (Patterns 1 and 2) was seeking substance-specific effects (e.g., stimulant effect from nicotine, relaxation effects from cannabis), while unique motives for temporally close patterns (Patterns 3 and 4) were seeking combined effects from both substances (e.g., more intense psychoactive effects, mitigating cannabis adverse effects) and behavioral trigger (e.g., cannabis use triggers tobacco use). CONCLUSIONS: Our classification of co-use patterns can facilitate consistency for measuring co-use and assessing its health impacts. Future research should also measure product types and motives for different patterns to inform intervention efforts.

Associations between tobacco and cannabis use and anxiety and depression among adults in the United States: Findings from the COVID-19 citizen science study.

BACKGROUND: Little is known about whether people who use both tobacco and cannabis (co-use) are more or less likely to have mental health disorders than single substance users or non-users. We aimed to examine associations between use of tobacco and/or cannabis with anxiety and depression. METHODS: We analyzed data from the COVID-19 Citizen Science Study, a digital cohort study, collected via online surveys during 2020-2022 from a convenience sample of 53,843 US adults (≥ 18 years old) nationwide. Past 30-day use of tobacco and cannabis was self-reported at baseline and categorized into four exclusive patterns: tobacco-only use, cannabis-only use, co-use of both substances, and non-use. Anxiety and depression were repeatedly measured in monthly surveys. To account for multiple assessments of mental health outcomes within a participant, we used Generalized Estimating Equations to examine associations between the patterns of tobacco and cannabis use with each outcome. RESULTS: In the total sample (mean age 51.0 years old, 67.9% female), 4.9% reported tobacco-only use, 6.9% cannabis-only use, 1.6% co-use, and 86.6% non-use. Proportions of reporting anxiety and depression were highest for the co-use group (26.5% and 28.3%, respectively) and lowest for the non-use group (10.6% and 11.2%, respectively). Compared to non-use, the adjusted odds of mental health disorders were highest for co-use (Anxiety: OR = 1.89, 95%CI = 1.64-2.18; Depression: OR = 1.77, 95%CI = 1.46-2.16), followed by cannabis-only use, and tobacco-only use. Compared to tobacco-only use, co-use (OR = 1.35, 95%CI = 1.08-1.69) and cannabis-only use (OR = 1.17, 95%CI = 1.00-1.37) were associated with higher adjusted odds for anxiety, but not for depression. Daily use (vs. non-daily use) of cigarettes, e-cigarettes, and cannabis were associated with higher adjusted odds for anxiety and depression. CONCLUSIONS: Use of tobacco and/or cannabis, particularly co-use of both substances, were associated with poor mental health. Integrating mental health support with tobacco and cannabis cessation may address this co-morbidity.

Perceptions of Safety of Daily Cannabis vs Tobacco Smoking and Secondhand Smoke Exposure, 2017-2021.

Importance: While rates of cigarette use are declining, more US adults are using cannabis. Perceptions of safety are important drivers of substance use and public policy; however, little is known about the comparative views of US adults on tobacco and cannabis safety. Objective: To compare public perceptions of safety of cannabis vs tobacco smoke and evaluate how perceptions may be changing over time. Design, Setting, and Participants: This longitudinal survey study was conducted using a web-based survey administered in 2017, 2020, and 2021. US adults participating in Ipsos KnowledgePanel, a nationally representative, population-based survey panel, were included. Data were analyzed from March 2021 through June 2023. Main Outcomes and Measures: Two questions directly compared the perception of safety of cannabis vs tobacco in terms of daily smoking and secondhand smoke exposure. Additional questions assessed perceptions of safety of secondhand tobacco smoke for adults, children, and pregnant women, with an analogous set of questions for secondhand cannabis smoke. Results: A total of 5035 participants (mean [SD] age, 53.4 [16.2] years; 2551 males [50.7%]) completed all 3 surveys and provided responses for tobacco and cannabis risk questions. More than one-third of participants felt that daily smoking of cannabis was safer than tobacco, and their views increasingly favored safety of cannabis vs tobacco over time (1742 participants [36.7%] in 2017 vs 2107 participants [44.3%] in 2021; P < .001). The pattern was similar for secondhand cannabis smoke, with 1668 participants (35.1%) responding that cannabis was safer than tobacco in 2017 vs 1908 participants (40.2%) in 2021 (P < .001). Participants who were younger (adjusted odds ratio [aOR] for ages 18-29 years vs ≥60 years, 1.4 [95% CI, 1.1-1.8]; P = .01) or not married (aOR, 1.2 [95% CI, 1.0-1.4]; P = .01) were more likely to move toward safer views of cannabis use over time, while those who were retired (aOR vs working, 0.8 [95% CI, 0.7-0.9]; P = .01) were less likely to move toward a safer view of cannabis. Participants were also more likely to rate secondhand smoke exposure to cannabis vs tobacco as completely or somewhat safe in adults (629 participants [12.6%] vs. 119 participants [2.4%]; P < .001), children (238 participants [4.8%] vs. 90 participants [1.8%]; P < .001), and pregnant women (264 participants [5.3%] vs. 69 participants [1.4%]; P < .001). Conclusions and Relevance: This study found that US adults increasingly perceived daily smoking and secondhand exposure to cannabis smoke as safer than tobacco smoke from 2017 to 2021. Given that these views do not reflect the existing science on cannabis and tobacco smoke, the findings may have important implications for public health and policy as the legalization and use of cannabis increase.

Young Adults' Perceptions of and Intentions to Use Nicotine and Cannabis Vaporizers in Response to e-Cigarette or Vaping-Associated Lung Injury Instagram Posts: Experimental Study.

BACKGROUND: Inhaling aerosolized nicotine and cannabis (colloquially called "vaping") is prevalent among young adults. Instagram influencers often promote both nicotine and cannabis vaporizer products. However, Instagram posts discouraging the use of both products received national media attention during the 2019 outbreak of e-cigarette or vaping-associated lung injury (EVALI). OBJECTIVE: This experiment tested the impact of viewing Instagram posts about EVALI, varying in image and text valence, on young adults' perceived harmfulness of nicotine and cannabis products, perceived risk of nicotine and cannabis vaporizer use, and intentions to use nicotine and cannabis vaporizers in the future. METHODS: Participants (N=1229) aged 18-25 (mean 21.40, SD 2.22) years were recruited through Qualtrics Research Services, oversampling for ever-use of nicotine or cannabis vaporizers (618/1229, 50.3%). Participants were randomly assigned to view Instagram posts from young people portraying their experiences of EVALI in a 2 (image valence: positive or negative) × 2 (text valence: positive or negative) between-subjects experiment. Positive images were attractive and aesthetically pleasing selfies. The positive text was supportive and uplifting regarding quitting the use of vaporized products. Negative images and text were graphic and fear inducing. After viewing 3 posts, participants reported the perceived harmfulness of nicotine and cannabis products, the perceived risk of nicotine and cannabis vaporizer use, and intentions to use nicotine and cannabis vaporizers in the future. Ordinal logistic regression models assessed the main effects and interactions of image and text valence on perceived harmfulness and risk. Binary logistic regression models assessed the main effects and interactions of image and text valence on intentions to use nicotine and cannabis vaporizers. Analyses were adjusted for product use history. RESULTS: Compared to viewing positive images, viewing negative images resulted in significantly greater perceived harm of nicotine (P=.02 for disposable pod-based vaporizers and P=.04 for other e-cigarette "mods" devices) and cannabis vaporized products (P=.01), greater perceived risk of nicotine vaporizers (P<.01), and lower odds of intentions to use nicotine (P=.02) but not cannabis (P=.43) vaporizers in the future. There were no significant main effects of text valence on perceived harm, perceived risk, and intentions to use nicotine and cannabis vaporized products. No significant interaction effects of image and text valence were found. CONCLUSIONS: Negative imagery in Instagram posts about EVALI may convey the risks of vaporized product use and discourage young adults from this behavior, regardless of the valence of the post's text. Public health messaging regarding EVALI on Instagram should emphasize the risk of cannabis vaporizer use, as young adults may otherwise believe that only nicotine vaporizer use increases their risk for EVALI.

Changes in perceived harms of tobacco and cannabis and their correlations with use: A panel study of young adults 2014-2020.

PURPOSE: Perceived harm is associated with substance use. Changes in product and policy landscapes may impact perceived harms of tobacco and cannabis. This study aimed to examine changes in young adults' perceived harms of tobacco and cannabis and their associations with use behavior during a period including both before and after legalization of cannabis. METHODS: We conducted a panel survey of California Bay Area young adults (mean age = 23.5 years old, 64.4% female) in 2014 and 2019-2020. Participants (N = 306) reported past 30-day use and perceived harms of tobacco and cannabis at both waves. Perceived harms to health of cannabis and tobacco (cigarettes, e-cigarettes, hookah, smokeless tobacco, and secondhand tobacco smoke) were measured from 1-"Not at all harmful" to 7-"Extremely harmful." Mixed-effects logistic regressions examined associations between perceived harms and use of tobacco and cannabis, controlling for demographics. RESULTS: Participants perceived lower harm for cannabis than for tobacco products. Perceived harms of e-cigarettes, hookah, and smokeless tobacco significantly increased over time; while perceived harms of cigarettes, secondhand tobacco smoke, and cannabis did not change. Increased perceived harm of e-cigarettes was associated with lower odds of any tobacco use (OR = 0.72, 95%CI = 0.56, 0.92), and increased perceived harm of cannabis was associated with lower odds of any cannabis use (OR = 0.51, 95%CI = 0.42, 0.62). CONCLUSIONS: Findings suggest that perceived harms of e-cigarettes and cannabis play important roles in driving young adult use behaviors. Risk communication efforts that increase perceptions of health harms related to e-cigarettes and cannabis may decrease use of tobacco and cannabis among young people.

Flavored Cannabis Use and Cannabis-Tobacco Co-use: Patterns In U.S. States With Legalized Nonmedical Adult Use.

INTRODUCTION: Little is known about inhaled flavored cannabis use. This study aimed to investigate the prevalence and patterns of flavored cannabis use and cannabis-tobacco co-use. METHODS: This study surveyed adult past 30-day cannabis users in U.S. states and districts that have legalized cannabis for nonmedical/adult use (n=9) (November 2018; n=2,978). By product/behavior (any cannabis, cannabis extract vaporizers, mixed cannabis-nicotine vaporizers, blunts, chasing), the association between flavored (versus non-flavored) use and sociodemographic characteristics, cannabis use disorder symptoms, and tobacco use was estimated using weighted multivariable logistic regression in January 2022. RESULTS: Almost half of adult cannabis users reported using at least one flavored cannabis product (46.5%). Flavored cannabis use was more likely among respondents who were female (AOR=1.2, CI=1.0, 1.4), were Black (ref: White; AOR=2.2, CI=1.5, 3.1), were Hispanic/Latino/a/x (ref: White; AOR=1.6, CI=1.2, 1.9), had cannabis use disorder symptoms (AOR=2.0, CI=1.6, 2.4), or were currently using tobacco (AOR=2.4, CI=2.1, 2.9). Use was less likely among middle-aged/older adults (ref: ages 21-34 vs 35-49 years; AOR=0.6, CI=0.5, 0.7). CONCLUSIONS: Observed differences in flavored cannabis use are concerning if flavors raise appeal or dependence. Integrating flavored cannabis and tobacco research and practice is warranted.

"I'm both smoking and vaping": a longitudinal qualitative study of US young adults who tried to quit smoking cigarettes by using electronic cigarettes.

OBJECTIVE: To describe how young adults use electronic cigarettes (electronic nicotine delivery systems (ENDS)) for smoking cessation and reasons why they may or may not successfully quit smoking. METHODS: Longitudinal qualitative data were collected annually from 2017 to 2019 for 25 young adult tobacco users (aged 18-29 years) in California (USA) who used ENDS to quit/reduce smoking. Thematic and trajectory analyses were used to identify key within-person and between-person changes in tobacco/nicotine use over time. RESULTS: Five types of tobacco use transition were identified among baseline dual users of cigarettes and ENDS: sustained dual use without reduced smoking (n=8), transition to exclusive daily ENDS use (n=6), sustained dual use with reduced smoking (n=5), transition back to exclusive smoking (n=4) and transition to neither smoking nor vaping (n=2). Participants' ENDS use behaviour varied over time in terms of vaping quantity and device characteristics (eg, changing nicotine concentrations/flavours, switching between multiple devices). Three themes that related to successfully replacing cigarettes with ENDS were perceived positive physical effects, perceived satisfaction and enjoyment and context changes. Four themes for unsuccessful replacement were perceived negative physical discomforts, perceived addictiveness and harm, unsatisfactory substitution for cigarettes and device malfunction. CONCLUSIONS: Young adults' experiences with using ENDS as a smoking cessation aid were highly variable. Adequate nicotine delivery and perceived safety and benefits contributed to successfully reducing or quitting cigarettes. Providing behavioural counselling and standardising ENDS products may enhance cessation for young adults.

Young Adult Responses to Peer Crowd-Based Targeting in E-cigarette Advertisements: An Experimental Study.

AIMS: To examine the effects of psychographically targeted e-cigarette advertisements on young adults. METHODS: A total of 2100 young adults (18-29 years old) representing five peer crowds (groups with shared values, interests, and lifestyle: Mainstream, Young Professional, Hip Hop, Hipster, and Partier) were recruited from a nationwide opt-in online panel. Participants were randomly assigned to view e-cigarette advertisements featuring characters that either did or did not match their own peer crowd affiliation and evaluated advertising effectiveness using Likert-type and semantic differential scales. Participants also reported their attitudes toward using e-cigarettes. RESULTS: No significant overall effect of peer crowd matching was observed. However, significant two-way interaction effects emerged where matching advertisements yielded higher evaluations than mismatching advertisements among those who currently do not use tobacco and nicotine products and among Mainstream participants. Advertisements featuring Mainstream characters were in general rated more highly than other advertisements. Additional analyses found significant effects of peer crowd matching among those who viewed advertisements featuring non-Mainstream characters. CONCLUSIONS: Peer crowd-based targeting can increase the effectiveness of e-cigarette advertisements which may impact initiation among current nonusers, requiring stricter marketing regulations. More research is needed to determine if anti-tobacco messaging tailored by peer crowds may effectively counteract targeted e-cigarette marketing. IMPLICATIONS: E-cigarette advertisements often use psychographic targeting strategies, using lifestyles, attitudes, and values. Low-risk young adults (eg, those who currently do not use tobacco and nicotine products) are susceptible to psychographically targeted e-cigarette advertisements. This may result in the initiation of e-cigarette use among young adults who would otherwise be less likely to use tobacco and nicotine products. Stricter marketing regulations for emerging tobacco and nicotine products are required to reduce marketing exposure.

Impacts of Tax and Flavor Tobacco Policies on San Francisco Bay Area Tobacco Prices.

California Proposition 56 increased the state tobacco tax by $2 per cigarette pack effective April 1, 2017. Between 2015-2020 San Francisco (SF) and some cities in Alameda County enacted local flavored tobacco sales restrictions. SF also increased its Cigarette Litter Abatement Fee, from $0.20/pack in 2015 to $1.00 in 2020. Compare the change in tobacco prices before (2015) and after (2019/20) the implementation of a $2 increase in tobacco excise tax and local flavored tobacco policies in SF and Alameda Counties. Descriptive study of the pre-to-post policy analysis design. We drew a proportional random sample of retailers (N=463) in SF and Alameda Counties, by city. Using multivariable, single- and multiple-level linear regressions, we compared inflation-adjusted average tobacco prices in 2015 vs. 2019/20 by county and by flavor policy, accounting for socio-demographics. Change in inflation-adjusted average tobacco prices in 2015 vs. 2019/20 by county and flavor policy, accounting for socio-demographics. Between 2015-2019/20, the increase in cigarette prices was higher than the $2 tax increase, and higher in SF than Alameda County (+$4.6 vs +$2.5). SF retailers stopped selling Newport menthol cigarettes and Blu brand menthol e-cigarettes in 2019/20. Adjusted average cigarette prices increased significantly more in SF and Alameda County cities with comprehensive or partial flavor policies versus cities without flavor policies (by $3.23 and $2.11). Local flavor policies affected menthol product availability and may have had positive spillover effects and indirectly increased pack prices.

Associations Between Product Type and Intensity of Tobacco and Cannabis Co-use on the Same Day Among Young Adult Smokers: Smartphone-Based Daily-Diary Study.

BACKGROUND: Co-use of tobacco and cannabis is highly prevalent among young US adults. Same-day co-use of tobacco and cannabis (ie, use of both substances on the same day) may increase the extent of use and negative health consequences among young adults. However, much remains unknown about same-day co-use of tobacco and cannabis, in part due to challenges in measuring this complex behavior. Nuanced understanding of tobacco and cannabis co-use in terms of specific products and intensity (ie, quantity of tobacco and cannabis use within a day) is critical to inform prevention and intervention efforts. OBJECTIVE: We used a daily-diary data collection method via smartphone to capture occurrence of tobacco and cannabis co-use within a day. We examined (1) whether the same route of administration would facilitate co-use of 2 substances on the same day and (2) whether participants would use more tobacco on a day when they use more cannabis. METHODS: This smartphone-based study collected 2891 daily assessments from 147 cigarette smokers (aged 18-26 years, n=76, 51.7% female) during 30 consecutive days. Daily assessments measured type (ie, cigarette, cigarillo, or e-cigarette) and intensity (ie, number of cigarettes or cigarillos smoked or number of times vaping e-cigarettes per day) of tobacco use and type (ie, combustible, vaporized, or edible) and intensity (ie, number of times used per day) of cannabis use. We estimated multilevel models to examine day-level associations between types of cannabis use and each type of tobacco use, as well as day-level associations between intensities of using cannabis and tobacco. All models controlled for demographic covariates, day-level alcohol use, and time effects (ie, study day and weekend vs weekday). RESULTS: Same-day co-use was reported in 989 of the total 2891 daily assessments (34.2%). Co-use of cigarettes and combustible cannabis (885 of the 2891 daily assessments; 30.6%) was most commonly reported. Participants had higher odds of using cigarettes (adjusted odds ratio [AOR] 1.92, 95% CI 1.31-2.81) and cigarillos (AOR 244.29, 95% CI 35.51-1680.62) on days when they used combustible cannabis. Notably, participants had higher odds of using e-cigarettes on days when they used vaporized cannabis (AOR 23.21, 95% CI 8.66-62.24). Participants reported a greater intensity of using cigarettes (AOR 1.35, 95% CI 1.23-1.48), cigarillos (AOR 2.04, 95% CI 1.70-2.46), and e-cigarettes (AOR 1.48, 95% CI 1.16-1.88) on days when they used more cannabis. CONCLUSIONS: Types and intensities of tobacco and cannabis use within a day among young adult smokers were positively correlated, including co-use of vaporized products. Prevention and intervention efforts should address co-use and pay attention to all forms of use and timeframes of co-use (eg, within a day or at the same time), including co-use of e-cigarettes and vaporized cannabis, to reduce negative health outcomes.

Tobacco-Derived Nicotine Pouch Brands and Marketing Messages on Internet and Traditional Media: Content Analysis.

BACKGROUND: Nicotine pouches and lozenges are increasingly available in the United States, and sales are growing. The brands of nicotine pouch products with the largest market share are produced by tobacco companies. OBJECTIVE: The aim of this study is to examine the marketing of 5 oral nicotine products sold by tobacco companies. METHODS: Internet, radio, television, print, and web-based display advertisements between January 2019 and March 2020 for 6 brands of nicotine pouches and lozenges were identified through commercially available marketing surveillance systems supplemented by a manual search of trade press and a review of brand websites. A total of 711 advertisements (122 unique) were analyzed to identify characteristics, themes, marketing strategies, and target audiences, and qualitatively compared by brand. All 5 brand websites were also analyzed. Coders examined the entirety of each advertisement or website for products, marketing claims, and features and recorded the presence or absence of 27 marketing claims and lifestyle elements. RESULTS: All 6 brands of nicotine pouch products spent a total of US $11.2 million on advertising in 2019, with the most (US $10.7 million) spent by the brand Velo, and 86.1% (n=105) of the unique advertisements were web-based. Of the 711 total nicotine pouch advertisements run in 2019, the 2 brands Velo (n=407, 57%) and ZYN (n=303, 42%) dominated. These brands also made the greatest number of advertising claims in general. These claims focused on novelty, modernity, and use in a variety of contexts, including urban contexts, workplaces, transportation, and leisure activities. Of the 122 unique advertisements, ZYN's most common claims were to be "tobacco-free," featuring many flavors or varieties, and modern. Velo was the only brand to include urban contexts (n=14, 38.9% of advertisements) or freedom (n=8, 22.2%); Velo advertisements portrayed use in the workplace (n=15, 41.7%), bars or clubs (n=5, 13.9%), leisure activities (n=4, 11.1%), transportation (n=4, 11.1%), sports (n=3, 8.3%), cooking (n=2, 5.6%), and with alcohol (n=1, 2.8%). Velo and ZYN also included most of the images of people, including women and people of color. The 36 Velo ads included people in advertising in 77.8% (n=28) of advertisements, and of those advertisements with identifiable people, 40% (n=4) were young adults and 50% (n=5) were middle-aged. About one-third (n=11, 35.5%) of the 31 unique ZYN advertisements included people, and most identifiable models appeared to be young adults. Brands such as Rogue, Revel, Dryft, and on! focused mainly on product features. All nicotine pouch products made either tobacco-free, smoke-free, spit-free, or vape-free claims. The most common claim overall was "tobacco-free," found in advertisements from Rogue (1/1, 100%), ZYN (30/31, 96.8%), Velo (19/36, 52.8%), and Dryft (1/3, 33.3%), but not Revel. CONCLUSIONS: Nicotine pouches and lozenges may expand the nicotine market as tobacco-free claims alleviate concerns about health harms and advertising features a greater diversity of people and contexts than typical smokeless tobacco advertising. The market leaders and highest-spending brands, ZYN and Velo, included more lifestyle claims. Surveillance of nicotine pouch marketing and uptake, including influence on tobacco use behaviors, is necessary.

'No-Barriers' tobacco product? Selling smokeless tobacco to women, people of colour and the LGBTQ+ community in the USA.

BACKGROUND: In both Sweden and the USA, smokeless tobacco (ST) is legal and used predominantly by men. Starting in the 1970s, US tobacco companies attempted to expand the ST market to women, African Americans, Hispanic Americans and lesbian, gay, bisexual, transgender, queer and other sexual orientation (LGBTQ+) people. DESIGN: We analysed industry documents from the Truth Tobacco Industry Documents Library triangulating findings with recent ST advertising and publicly available literature. FINDINGS: We found tobacco companies used design innovations such as pouched moist snuff, snus and dissolvable products to expand the market. In addition, diverse advertising campaigns targeted women, people of colour (Hispanic, African American) and LGBTQ+ communities with identity-targeted messages emphasising novelty, convenience, cleanliness and use in smoke-free environments. However, stereotypes of ST users as rural white males endured, perpetuated by continued marketing aimed at this customer base, which created cognitive dissonance and stymied marketer's hopes that pouch products would 'democratize' ST. CONCLUSION: These failed campaigns suggest novel products such as nicotine pouch products may provide a 'clean slate' to similarly target women and other low-ST-using groups. Based on this history, the risk of new tobacco and nicotine products to increase health disparities should be closely monitored.

Delivering vaping cessation interventions to adolescents and young adults on Instagram: protocol for a randomized controlled trial.

BACKGROUND: Adolescent and young adult use of electronic nicotine delivery systems ("vaping") has increased rapidly since 2018. There is a dearth of evidence-based vaping cessation interventions for this vulnerable population. Social media use is common among young people, and smoking cessation groups on social media have shown efficacy in the past. The objective of this study is to describe the protocol for a randomized controlled trial (RCT) testing the efficacy of an Instagram-based vaping cessation intervention for adolescents and young adults. METHODS: Adolescents and young adults aged 13-21 residing in California who have vaped at least once per week in the past 30 days will be recruited through social media ads, community partners, and youth serving organizations. Participants will be randomly assigned to intervention or control conditions: the intervention group takes place on Instagram, where participants receive up to 3 posts per weekday for 25 days over 5 weeks; the control group will be directed to kickitca.org, a website offering links to chatline and texting cessation services operated by the California Smokers' Helpline. The primary outcome is biochemically verified 7-day point prevalence abstinence for nicotine vaping; secondary outcomes are vaping reduction by 50% or more, vaping quit attempts, readiness to quit vaping, confidence in ability to quit, desire to quit, commitment to abstinence, and use of evidence-based cessation strategies. Both the primary outcome and secondary outcomes will be assessed immediately, 3 months, and 6 months after the treatment. DISCUSSION: This is the first RCT to test a vaping cessation intervention delivered through Instagram. If effective, it will be one of the first evidence-based interventions to address vaping among adolescents and young adults and add to the evidence base for social media interventions for this population. TRIAL REGISTRATION: ClinicalTrials.gov: NCT04707911, registered on January 13, 2021.

Perceptions and Aspirations Toward Peer Mentoring in Social Media-Based Electronic Cigarette Cessation Interventions for Adolescents and Young Adults: Focus Group Study.

BACKGROUND: Social media offer a promising channel to deliver e-cigarette cessation interventions to adolescents and young adults (AYAs); however, interventions delivered on social media face challenges of low participant retention and decreased engagement over time. Peer mentoring has the potential to ameliorate these challenges. OBJECTIVE: The aim of this study was to understand, from both the mentee and potential mentor perspective, the needs, expectations, and concerns of AYAs regarding peer mentoring to inform the development of social media-based peer mentoring interventions for e-cigarette cessation among AYAs. METHODS: Seven focus groups, including four mentee groups and three potential mentor groups, were conducted with 26 AYAs who had prior experience with e-cigarette use and attempts to quit in the context of a social media-based e-cigarette cessation intervention. Discussion focused on preferred characteristics of peer mentors, expectations about peer mentoring, mentoring mode, mentor training, incentives for peer mentors, preferred social media platforms for intervention delivery, supervision, and concerns. Focus group transcripts were coded and analyzed using a thematic analysis approach. RESULTS: Overall, participants were receptive to peer mentoring in social media-based cessation interventions and believed they could be helpful in assisting e-cigarette cessation. Participants identified the most important characteristics of peer mentors to be of similar age and to be abstinent from e-cigarette use. Participants expected peer mentors would share personal experiences, provide emotional support, and send check-ins and reminders. Peer mentors supporting a group of mentees in combination with one-on-one mentoring as needed was the preferred mentoring mode. A group of 10 mentees with a mentor:mentee ratio of 1:3-5 was deemed acceptable for most participants. Participants expressed that mentor training should include emotional intelligence, communication skills, and the scientific evidence about e-cigarettes. Although monetary incentives were not the main motivating factor for being a peer mentor, they were viewed as a good way to compensate mentors' time. Instagram was considered an appropriate social media platform to deliver a peer-mentored intervention due to its functionality. Participants did not express many privacy concerns about social media-based peer mentoring, but mentioned that boundaries and community agreements should be set to keep relationships professional. CONCLUSIONS: This study reflects the needs and preferences of young people for a peer mentoring intervention to complement a social media program to support e-cigarette cessation. The next step will be to establish the feasibility, acceptability, and preliminary efficacy of such a peer mentoring program.

Policies restricting flavors and non-cigarette tobacco product availability: A study of vape shops in San Francisco and Alameda Counties, California, USA.

We examined flavored non-cigarette tobacco availability in brick-and-mortar vape shops in San Francisco (SF) and Alameda Counties, California (USA), comparing cities organized by flavored tobacco sales restriction policy. A total of 22 brick-and-mortar vape shops were identified and audited in October-November 2019; shops were located in SF City-County and nine cities in Alameda County. Fisher Exact Tests were used to assess differences in the availability of products between vape shops in cities with versus without comprehensive or partial flavored tobacco sales restrictions enacted before November 21, 2019 (n = 15 shops in six cities with policies vs n = 7 shops in four cities without policies). In the six cities with any flavored sales restrictions, fewer vape shops sold menthol/mint flavored JUUL pods (27% vs 71%, p = 0.074), candy/fruit (53% vs 100%, p = 0.051) and menthol/mint (53% vs 100%, p = 0.051) nicotine e-cigarette liquids compared to cities without flavored tobacco sales restrictions, but results were borderline significant. Tobacco-flavored JUUL pods (47% vs 71%, p = 0.381), tobacco-flavored nicotine e-cigarette liquids (67% vs 100%, p = 0.135), and flavored e-cigarette liquids without nicotine (candy/fruit: 87% vs 71%, p = 0.565 and menthol/mint: 87% vs 57%, p = 0.274) were not included in the policies, and availability was not significantly different between cities with or without policies. Enactment of local policies was associated with lower flavored e-cigarette tobacco product availability but not tobacco-flavored or non-nicotine product availability; federal policies restricting sales of flavored tobacco products may reduce access to flavored e-cigarette products in vape shops.

A Systematic Review of E-Cigarette Marketing Communication: Messages, Communication Channels, and Strategies.

Marketing plays a key role in increasing the popularity of e-cigarettes. We conducted a systematic review of the existing literature published between 2003 and 2019 in eight databases to describe e-cigarette marketing communication messages by communication channels and marketing communication strategies. Forty-one articles were included in the analysis after screening. Ten key messages were identified. Cessation and health-related benefits (each n = 31, 75.6%) were the most reported marketing communication messages, followed by sociability/lifestyle and use experience. The Internet (n = 32, 78.0%) was the most studied communication channel compared to print, TV/movie/radio, and point-of-sales (POS)/retail stores. The most studied marketing communication strategies were advertising (n = 28, 68.3%), followed by public relations and sales promotion. Published research studies reported consistent messages about e-cigarettes across communication channels and marketing communication strategies. Claims of smoking cessation and health-related benefits were widely identified in the existing literature. While therapeutic claims are prohibited, soft sell messages, such as social appeals, for which regulatory reach may be limited, may require educational campaigns. Internet marketing has attracted much attention, with limited studies on messages in print, TV/movie/radio, and POS/retail stores. The lack of studies of direct marketing messaging indicates a big gap between industry spending and academic research; more studies of messaging utilizing this strategy are needed.
