Tirzepatide in the Treatment of Cannabis Use Disorder

2026年6月29日 更新者：M. Van Ameringen、McMaster University

A 12-Week Phase 3 Clinical Trial to Evaluate the Safety, Tolerability and Efficacy of Tirzepatide-Assisted-Psychotherapy in Adults With Cannabis Use Disorder: A Proof-of-Concept Study

Cannabis is the most commonly used psychoactive substance in Canada. A sub-group of cannabis users develop Cannabis Use Disorder (CUD). CUD is a pattern of cannabis use that results in impairment in functioning, symptoms of tolerance, withdrawal, and distress. Several pharmacological and psychosocial interventions have been evaluated for their efficacy in treating CUD, however they lack high success rates. GLP-1RA's have shown promising results in reducing food and alcohol cravings and intake. Tirzepatide acts as both a GLP-1RA and a glucose-dependent insulinotropic polypeptide receptor agonist. Tirzepatide has been reported to reduce alcohol consumption, and therefore may have promising effects as a treatment for CUD. This study aims to evaluate the feasibility and tolerability of weekly injections of Tirzepatide combined with Motivational Enhancement Therapy in adults with CUD. This trial will be the first to examine the potential therapeutic effects of Tirzepatide in CUD.
