Purpose of Review The purpose of this review was to describe the state-of-the-literature on research specific to cannabis vaping among youth and young adults. Recent Findings Out of 1801 records identified, a total of 202 articles met eligibility criteria for inclusion in this review. Most of this literature (46.0% of studies) was specific to the health effects of cannabis vaping, particularly EVALI (e-cigarette and vaping associated lung injury). Other research areas identified in the review included the etiology (24.3%) and epidemiology (24.8%) of cannabis vaping, in addition to articles on regulation (8.4%) and marketing (5.5%) of the same. Summary Cannabis vaping is increasingly common among youth and young adults and more prevalent is settings where recreational use for adults has been legalized. The literature documents a number of negative health effects of cannabis vaping for young people, along with risk factors and reasons for the same.

Background Studies show smoking and vaping behaviors increase risk of contracting and worse symptoms of COVID-19. This study examines whether past 30-day youth and young adult users of marijuana, e-cigarettes, and cigarettes self-reported changes in their use of these substances due to the COVID-19 pandemic; and cross-sectional associations between perceived stress, nicotine or marijuana dependence, and COVID-19–related changes in use. Methods Participants were 709 past 30-day self-reported substance users from the Texas Adolescent Tobacco and Marketing Surveillance study (TATAMS; mean age = 19; 58% female; 38% Hispanic, 35% white). Multiple logistic regression models assessed cross-sectional associations between perceived stress and dependence and increased, decreased, or sustained past 30-day use of marijuana, e-cigarettes, and cigarettes due to COVID-19 (e.g., “Has your marijuana use changed due to the COVID-19 outbreak?”). Covariates included age, race/ethnicity, socio-economic status (SES), dependence (exposure: stress), and stress (exposure: dependence). Results Most participants reported sustained (41%, 43%, 49%) or increased (37%, 34%, 25%) use of marijuana, e-cigarettes, and cigarettes due to COVID-19, respectively. Participants who reported symptoms of dependence were significantly more likely than their non-dependent peers to report increasing their marijuana (AOR: 1.66; 95% CI: 1.15–2.39) and e-cigarette (AOR: 2.57; 95% CI: 1.38–4.77) use. Those who reported higher perceived stress were significantly more likely to report increasing their marijuana use (AOR: 1.55; 95% CI: 1.01–2.42). Conclusions Most youth and young adults did not decrease their substance use amid a global, respiratory disease pandemic. Health messaging and interventions that address the health effects of smoking and vaping as well as factors like stress and dependence that may be barriers to decreasing use are vital in curbing the COVID-19 pandemic.

Introduction This study examined patterns in mental health symptomatology and smoking and vaping behaviors among youth and young adults over a one-year period from before to during the first year of the COVID-19 pandemic. Methods Participants (n=2,148) were 16-24-year-olds who completed three waves of the Texas Adolescent Tobacco and Marketing Surveillance Study (TATAMS). Descriptive statistics and mixed effects logistic regression models were used to examine changes in anxiety symptoms, depressive symptoms, perceived stress, and cigarette, e-cigarette, and marijuana use from before COVID-19 (fall 2019) to 6-month follow-up (spring 2020) and 12-month follow-up (fall 2020) periods during COVID-19. Longitudinal associations between mental health symptomatology and smoking and vaping were examined. Results Modest increases in symptoms of anxiety and depression were observed from before to during COVID-19. Perceived stress remained high and unchanged. Ever marijuana use increased at 6- and 12-month follow-up, while ever cigarette and e-cigarette use increased significantly only at 12-month follow-up. Marijuana use frequency increased significantly at 6- and 12-month follow-up. Adjusting for socio-demographic factors, increased symptoms of anxiety and depression predicted increases in ever cigarette, e-cigarette, and marijuana use, and past 30-day cigarette and e-cigarette use, but not past 30-day marijuana use. Higher perceived stress predicted increases in ever use of cigarettes and e-cigarettes, and past 30-day cigarette use. Conclusions Changes in mental health symptomatology and smoking and vaping behaviors among young people in Texas varied during this period of the COVID-era. Increases in mental health symptomatology predicted increases in cigarette, e-cigarette, and marijuana use behaviors. Implications This study adds to limited research on the longitudinal impact of anxiety symptoms, depressive symptoms, and perceived stress on cigarette, e-cigarette, and marijuana use from before to during the first year of the COVID-19 pandemic. Findings warrant health messaging and interventions that address the significant impact of worse mental health on increased smoking and vaping behavior, especially during crises like COVID-19 that may exacerbate mental health and substance use behaviors.
