A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This clinical trial is a double-blind, placebo-controlled study that aims to evaluate the effectiveness of full spectrum and broad spectrum cannabidiol (CBD) in reducing alcohol consumption among individuals diagnosed with moderate alcohol use disorder. Participants will be randomly assigned to receive either CBD or a placebo for a duration of 12 weeks. The study will assess various outcomes, including changes in drinking behavior, alcohol cravings, inflammation markers, anxiety levels, and sleep quality. The trial also seeks to determine the safety and tolerability of CBD, particularly the effects of the small amount of THC present in full spectrum CBD.
