Evaluation of the characteristics of individuals presenting for substance abuse treatment can provide important information to help focus treatment services. In this study, demographic and clinical characteristics of individuals presenting for medication trials for the treatment of cocaine or marijuana dependence were compared. Marijuana-dependent subjects were generally younger than cocaine-dependent subjects, more likely to be Caucasian, and completed more years of education. Marijuana-dependent subjects also reported significantly more days using than cocaine-dependent subjects, as well as higher levels of craving. Some differences in psychiatric symptomatology were also noted, with cocaine-dependent subjects more likely to report anxiety symptoms and marijuana-dependent subjects reporting more past depressive episodes. Past and current other drug use was similar between the two groups. These results highlight the significant impairments associated with marijuana and cocaine dependence.
