Associations between substance use and oppositional defiant disorder among U.S. adolescents: A national study of high-prevalence subgroups
This national study of over 226,000 U.S. adolescents found that cannabis use has the strongest association with oppositional defiant disorder (ODD), while machine learning analysis identified male adolescents aged 12–17 who use alcohol but not cannabis as the subgroup with the highest predicted probability of ODD, supporting the need for targeted screening in school settings.
