People in the US Receiving Mental Health Services Who Have a Co-Occurring Substance Use Disorder, by Diagnosis

"In the 2015 reporting period, mental health diagnoses among individuals served who had co-occurring mental health and substance use disorders differed very little by substance use diagnosis. (Unlike mental health diagnoses, where up to three diagnoses are recorded per client record, each client record contains only one substance use diagnosis. See the final section of Appendix E for definitions of substance abuse codes.)

"• Bipolar disorders were the most frequently reported mental health diagnoses for individuals served who had co-occurring marijuana dependence (29 percent).

"• Depressive disorders were the most frequently reported diagnoses for individuals served who had co-occurring alcohol dependence (36 percent), opioid dependence and non-dependent opioid use (35 percent each), or cocaine dependence (30 percent).

"• Bipolar disorders were the most frequently reported mental health diagnoses for individuals served who had co-occurring non-dependent cocaine use (29 percent), non-dependent marijuana use (26 percent), or other non-dependent substance use (26 percent).

"• Depressive disorders and bipolar disorders were the most frequently reported diagnoses for individuals served who had co-occurring non-dependent alcohol use (31 and 25 percent, respectively)."
