Social media use and cannabis vaping initiation among US youth

Youth cannabis vaping has increased in recent years, and there is growing evidence of cannabis vaping content on social media. This study investigated if social media use is associated with the initiation of cannabis vaping among US youth, using the youth dataset from Population Assessment of Tobacco and Health (PATH) Study Waves 4 (2016-2018) and 5 (2018-2019).

Using youth respondents who never vaped cannabis at Wave 4 (N=8357), we conducted a multivariable logistic regression analysis on initiation of cannabis vaping at Wave 5 (i.e., ever-vaped cannabis) by frequency of social media use, after controlling for covariates (e.g., sociodemographic, other tobacco and substance use).

In this analytic sample, 66.5% reported daily social media use, 16.2% reported non-daily and 17.3% reported 'not having a social media account' or 'no social media use' at Wave 4. Further, 14.0% (n=1183) initiated cannabis vaping at Wave 5. In the multivariable logistic regression model, daily social media use (vs. never use; aOR=2.68; 95% CI=2.05, 3.49) and non-daily social media use (vs. never use; aOR=1.54; 95% CI=1.14, 2.09) at Wave 4 were associated with cannabis vaping initiation at Wave 5.

Our evidence suggests that social media use by youth is associated with cannabis vaping initiation among youth in subsequent years, even after controlling for other risk factors. Consistent surveillance and regulation of cannabis vaping-related content on social media, as well as prevention efforts, including counter-messaging on social media about the potential harms of cannabis vaping, are critically needed.
