Summary

This study is testing whether cannabidiol (CBD) can help people who drink alcohol regularly cut down on their drinking. Researchers are giving 150 adults either full-spectrum CBD, broad-spectrum CBD, or a placebo daily for 12 weeks. They will measure how much participants drink in a lab setting and through self-reports, as well as blood markers of alcohol use. The goal is to see if CBD can be a safe, effective tool for managing alcohol use disorder.

What this could mean

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

Active substance
Cannabidiol (CBD) – either full-spectrum (with trace THC) or broad-spectrum (no THC)
What this could lead to
If it works, this could point toward a new, non-addictive option to help people drink less and avoid alcohol-related harm.
What could go wrong
This is a mid-stage trial with only 150 participants, so results may not apply to everyone. CBD may not reduce drinking more than a placebo, and some people may experience side effects.
