Facilitating the Behavioral Treatment of Cannabis Use Disorder

• Status: Completed
• Trial end date: 2018-08-01
• Target enrollment: 0
• Participant gender: All

Summary

Cannabis use disorders remain a significant public health problem. The pharmacological facilitation of behavioral treatment represents a promising strategy for addressing disordered cannabis use. Cannabis use disorders are recognized to be associated with various vulnerabilities that complicate the course of treatment and that may be amenable to glutamate modulators. The purpose of this single blind open-label trial is to test the feasibility of administering glutamate modulators in conjunction with motivational enhancement therapy (MET) and mindfulness based relapse prevention (MBRP) for cannabis use disorders.
