Hussong, & Colder, 1996; Hussong, Zucker, Wong, Fitzgerald, & Puttler, 2005). Most notably, COAs show a substantially greater risk for alcohol and drug use disorders in young adulthood. COAs initiate substance use earlier, increase their rates of use more quickly, and show a faster escalation from initiation to alcohol use disorders than do children of non-alcoholic parents (Chassin et al., 1996; Chassin et al., 1999; Hussong, Bauer, & Chassin, 2008). By young adulthood, 53% of COAs evidence an AUD as compared to 25% of non-COAs. Moreover, rates of drug, affective, and anxiety disorders are approximately 21, 24 and 25% among COAs compared to 9, 12 and 18% among their peers, respectively (Chassin et al., 1999).
