Associations Between Tobacco and Cannabis Use and Anxiety and Depression Among Adults in the United States: Findings from...

Course overview

The study investigated the mental health impacts of tobacco and cannabis use among 53,843 US adults. Data were collected via online surveys from 2020 to 2022, focusing on four groups: tobacco-only users, cannabis-only users, co-users of both substances, and non-users. The results indicated that co-users reported the highest rates of anxiety (26.5%) and depression (28.3%), followed by single-substance users, with non-users having the lowest rates (10.6% anxiety and 11.2% depression). The study used Generalized Estimating Equations to reveal that co-use of tobacco and cannabis was associated with the highest odds of mental health disorders, highlighting a significant public health concern exacerbated by the COVID-19 pandemic.
