Summary

This study is testing whether 12 weeks of group cognitive behavioral therapy (CBT) can help people reduce their alcohol or cannabis use. Researchers will enroll 400 adults with alcohol use disorder or cannabis use disorder. Participants will attend weekly CBT sessions, and the study will track changes in drinking days, cannabis use, and cravings.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
cognitive behavioral therapy (CBT)
What this could lead to
If successful, this could show that CBT is an effective way to reduce alcohol and cannabis use and cravings.
What could go wrong
This is a relatively small, early-stage study without a placebo group, so results may not be conclusive. The therapy requires commitment and may not work for everyone.
