Brief Marijuana Dependence Counseling (BMDC) is a 12-week intervention designed to treat adults with a diagnosis of cannabis dependence. Using a client-centered approach, BMDC targets a reduction in the frequency of marijuana use, thereby reducing marijuana-related problems and symptoms. BMDC is based on the research protocol used by counselors in the Center for Substance Abuse Treatment’s Marijuana Treatment Project conducted in the late 1990s. A treatment manual provides guidelines for counselors, social workers, and psychologists in both public and private settings. BMDC is implemented as a 9-session multicomponent therapy that includes elements of motivational enhancement therapy (MET), cognitive behavioral therapy (CBT), and case management.
