Cannabis use and associated longitudinal transitions in electronic nicotine delivery systems use among young adults in the United States.

Objective: Cannabis is increasingly the first substance used by young people and research indicates that cannabis use may precede the onset of tobacco use. Little is known, however, about the role of cannabis use in stages of electronic nicotine delivery systems (ENDS) uptake and progression across young adulthood. This study examined the associations between past 30-day (P30D) cannabis use frequency and transitions in ENDS use among young adults.

Problematic social media use and vaping among Mexican-American college students.

Introduction: Social media use and vaping nicotine are highly prevalent in the daily lives of young adults, especially among Mexican-American college students. The excessive and compulsive use of social media platforms, coupled with the urge to stay continuously connected, can lead to problematic social media use. To date, no studies have explored the impact of problematic social media use on the daily patterns of vaping among this vulnerable population.

Exposure to tobacco retail outlet tobacco marketing and initiation of cigarette and e-cigarette use: Depressive symptoms as a moderator.

Introduction: While tobacco retail outlet (TRO) marketing exposure has been associated with tobacco use, little research has explored how this relationship may vary by the experience of depressive symptoms. The purpose of this study was to examine if the relationship between TRO tobacco marketing exposure and tobacco use initiation is moderated by depressive symptoms among young adults.

Methods: Participants were drawn from 24 colleges in Texas who were participating in a multi-wave cohort study (2014-2019).

Tobacco use behaviors on college campuses in Texas: What, where, and who.

Examine tobacco use on college campuses by assessing: (1) types of tobacco products used, (2) where they are most commonly used, and (3) the sociodemographic characteristics of students most likely to use on campus. Participants were a convenience sample of 3,575 18- to 25-year-old enrolled in 14 Texas colleges during Spring 2021 who used at least one tobacco product in the past 30-days. Over 60% of participants used tobacco on their campus, and among these, nearly 93% used electronic nicotine delivery systems (ENDS) on campus.

Depressive symptoms and vaping: The mediating effect of outcome expectancies among young adults.

Objective: The purpose of the present study was to determine if positive affect reinforcement and social enhancement outcome expectancies mediate the longitudinal association between depressive symptoms and frequency of electronic nicotine delivery systems (ENDS) use one year later among young adults.

Method: Participants were 1567 young adults participating in the first three waves of the Marketing and Promotions Across Colleges in Texas project. At Wave 1 participants were 18-25 years old (M = 20.

Trajectories of depressive symptoms among young adults in Texas 2014-2018: a multilevel growth curve analysis using an intersectional lens.

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.

Electronic nicotine delivery systems use predicts transitions in cigarette smoking among young adults.

Background: Although cigarette smoking during young adulthood is characterized by volatility, few studies examine if use of electronic nicotine delivery systems (ENDS) impacts transitions in cigarette use behaviors across this developmental period. The purpose of this longitudinal study was to examine the role of ENDS use on three transitions in cigarette smoking among young adults; initiation, desistance, and re-uptake.

Methods: Participants were 5029 18-29-year-olds (64.
