Background and ObjectivesLimited research has examined mechanisms, including parenting behaviors, contributing to tobacco use disparities among sexual minority young adults (SMYAs).MethodsParticipants were 644 young adult (ages 18–29; 36.5% racial/ethnic minority) women (N = 416; 44.7% bisexual, 7.2% lesbian, 48.1% heterosexual) and men (N = 288; 11.0% bisexual, 13.2% gay, 75.9% heterosexual). Bivariate analyses examined differences among sex‐by‐sexual identity subgroups in perceived parenting (psychological control, behavioral control, knowledge, autonomy support, warmth, communication), past 30‐day cigarette, e‐cigarette, and cigar use, and likelihood of future use. Multivariable regression examined associations of sexual identity subgroup and parenting behaviors to tobacco use outcomes among women and men.ResultsBisexual (vs. heterosexual) women reported greater parental psychological control and less autonomy support, warmth, and communication. Bisexual (vs. heterosexual) women had greater odds of past 30‐day cigarette and cigar use and greater likelihood of future cigarette and e‐cigarette use, and parenting behaviors were associated with past 30‐day cigarette (knowledge, warmth), e‐cigarette (psychological control, autonomy support, warmth), and cigar use (behavioral control, warmth) and likelihood of future cigarette (psychological control, warmth) and e‐cigarette use (autonomy support, communication). Gay (vs. heterosexual) men reported greater parental behavioral control, less knowledge, autonomy support, warmth, and communication. Sexual identity and parenting behaviors were largely not associated with tobacco use among men.Discussion and ConclusionsFindings highlight the role of parenting behaviors as potential mechanisms contributing to tobacco use disparities among SMYA women.Scientific SignificanceTobacco prevention/cessation programs should be tailored toward specific SMYA subgroups, combinations of parenting behaviors, and patterns of tobacco use.

Background Cannabis marketing exposure via social media may impact use in youth and young adults. Most states with recreational cannabis lack policies regarding social media-based marketing. Thus, we examined such policies among prominent platforms, particularly those popular among youth and young adults. Methods In September-October 2022, 3 research team members extracted policies applying to the general community, advertising, and any specific content regarding drug-related content for 11 social media sites: Discord, Facebook, Instagram, Pinterest, Reddit, Snapchat, TikTok, Tumblr, Twitch, Twitter, and YouTube. Using inductive thematic analysis, they then dual-coded restrictions on cannabis-related content (e.g., paid advertising, unpaid promotion, sales). Descriptive analyses were conducted. Results Ten (all except TikTok) referenced cannabis/marijuana, 7 (all except Discord, Instagram, TikTok, and YouTube) distinguished different cannabis-derived products, and 5 (Reddit, Snapchat, TikTok, Tumblr, Twitter) noted jurisdictional differences in cannabis regulations/legality. All prohibited sales, 9 (all except Snapchat and Tumblr) prohibited paid advertising, and 4 (Discord, Reddit, Snapchat, TikTok) prohibited unpaid promotion (e.g., user-generated content). All restricted underage access to cannabis-related content. However, policies varied and were ambiguous regarding how “promotion” was defined, whether/how jurisdictional differences in legality were addressed, how businesses may interact on social media, barriers implemented to inhibit the facilitation of sales, and enforcement protocols. Conclusions Social media policies regarding cannabis marketing are ambiguous and may facilitate cannabis marketing, promotion, sales, and underage exposure, thus compounding concerns regarding insufficient governmental regulations. Greater specificity in social media cannabis-related policies and enforcement is needed.
