Increases in cannabis use and negative emotions during COVID-19 pandemic among college students with cannabis use disorder

Using cross-sectional baseline measurements from a longitudinal cohort study, we evaluated the perceived impact of the Coronavirus Disease 2019 (COVID-19) pandemic on cannabis use and emotional well-being among college students meeting cannabis use disorder (CUD) criteria (N = 150). Compared to before the pandemic, participants retrospectively reported an increase in cannabis use during the first phase of the pandemic when stay-at-home orders occurred, which was correlated with a greater number of CUD symptoms and cannabis use-related consequences since the pandemic began. Reporting greater frequency of cannabis use during the pandemic was associated with greater frequency of using amphetamine-type drugs and consumption of cannabis by dabbing since the pandemic began. There were significant differences in cannabis use-related outcomes as a function of negative emotions (e.g., feeling lonely/stressed/anxious/depressed) experienced during the pandemic. The findings elucidate the impact of the pandemic on cannabis use among college students with CUD and can inform prevention/intervention efforts in this population.
