First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study tests a talking therapy called the Cannabis Clinic for Psychosis (CCP) to help people with first-episode psychosis reduce or stop cannabis use. The therapy includes motivational interviewing and cognitive behavioral therapy in weekly sessions over 12 weeks. Researchers will compare the therapy group to a waiting-list group receiving usual care, measuring changes in cannabis use. The goal is to see if this approach can improve outcomes and reduce relapses.

What this could lead to

If it works, this could provide an effective non-drug treatment to help people with psychosis cut down or quit cannabis, potentially reducing relapses and hospital stays.

What could go wrong

This is a small early-stage trial with only 80 participants, and it uses a waiting-list design. The therapy may not work for everyone, and results may not apply to broader populations.
