The COVID-19 pandemic caused disruptions to treatment of substance use disorder, the availability of drugs, and other social factors that influence drug use.1 In June 2020, more than 10% of adults had started or increased substance use to cope with the pandemic,2 which could include using cannabis. The divergence in state-by-state policies governing cannabis sales in the US could create differences in who might use cannabis and for what reasons, particularly because stress can be a catalyst for substance use. In this cross-sectional study, we analyzed changes in prevalence of cannabis use during the pandemic within different legal frameworks and evaluated differences in associated behaviors.
