%X Over the past two decades, vaping has increased in popularity among young adults. Yet, little is known about the daily activities or contexts associated with vaping behavior. The current study examined whether nicotine vaping, cannabis vaping, and dual-substance vaping (i.e., vaping both nicotine and cannabis) fluctuated in tandem with alcohol use and activities on a given day. Data came from the Monitoring the Future Vaping Supplement, a national sample of U.S. young adults. A subsample of people who vaped (N = 330 people) completed up to 14 daily surveys (N = 3686 days). Multilevel logistic regressions separated within- and between-person characteristics and controlled for combustible nicotine and cannabis use, day of the week, and demographic characteristics. Weights accounted for the complex survey design and attrition. Results demonstrated that nicotine vaping was more common on days when participants drank moderately or binge drank (compared to not drinking), used cigarettes, and spent more time at bars and parties than usual. Cannabis vaping on a given day was more likely on days when young adults drank moderately and spent more time at bars/parties. Likewise, moderate drinking, spending more time at bars/parties than usual, and spending less time on schoolwork than usual was associated with a higher likelihood of dual-substance vaping on a given day. Our findings highlight when young adults vape nicotine and cannabis, while also identifying proximal correlates of these behaviors to inform intervention and cessation efforts.
