Marijuana abuse and dependence have been associated with a number of negative sequelae, including psychiatric disorders (e.g., major depression), reduced educational attainment, and unemployment (Kosty et al., 2017; Pacek et al., 2012). As of 2013, marijuana use disorders have disproportionately affected African-American adults, with 4.6% meeting diagnostic criteria for a marijuana use disorder compared to 2.7% and 2.8% of Caucasian and Hispanic adults, respectively (Hasin et al., 2015). Substantial changes in policy and public opinion surrounding marijuana use have prompted several states to legalize marijuana, resulting in African-American young adults having greater access to this substance.
