Cannabis is one of the most commonly used psychoactive substance in the United States (U.S.), with 7.3% of the U.S. general population reporting use in the past month in 2012 (SAMHSA, 2013). The widespread use of cannabis is of public health importance; cannabis use is associated with a host of social, psychological, and physical impairments, including financial difficulties, low energy levels, dissatisfaction with productivity levels, sleep and memory issues, and relationship and family problems (Gruber et al., 2003; Stephens et al., 2002). Most individuals receiving cannabis use disorder (CUD) treatment report difficulty quitting, and experience a withdrawal syndrome after cessation (Budney et al., 2007a). In light of the negative effects of cannabis use, continued examination of characteristics that are associated with cannabis use, particularly regular cannabis use, is prudent.
