The purpose of this study is to examine the effects of a seven-day combined contingency management (CM) with two sessions of brief Motivation Interviewing (MI) followed by standardized individual drug counseling on cannabis use and relapse in the following 90-day period in individuals with moderate to severe Cannabis Use Disorder (DSM-5).

Detailed description

The primary aim of this study is to examine cannabis use and rates of abstinence and relapse in individuals with moderate to severe Cannabis Use Disorder (CUD) after intensive 7-day contingency management (CM) procedure to reinforce abstinence from cannabis use. In addition, this study will evaluate the effect of CM with two sessions of brief MI on the severity of cannabis withdrawal signs during the first 7-days of CM treatment and then during the following month. The study will also focus on prospectively monitoring the sustenance of abstinence and time to lapse and relapse to cannabis use over a 90-day period, using ecological momentary assessment (EMA) via a smartphone-based application. An additional aim will be to evaluate changes in symptoms of CUD during the period following the 7-day using the diagnostic criteria of the DSM-5.
