Cannabidiol (CBD) for Alcohol Use Disorder

This study aims to understand how different forms of Cannabidiol (CBD) affect drinking habits in people who regularly consume alcohol. Researchers are testing two types of CBD: Full-Spectrum Cannabidiol (which contains less than 0.3% THC) and Broad-Spectrum Cannabidiol (which contains 0% THC), against a placebo (an inactive substance). They want to see if CBD can help reduce alcohol consumption and related problems. You might be able to join if you are between 21 and 65 years old, have used CBD and cannabis in the past year, and regularly drink alcohol. The study will measure changes in your drinking behavior and alcohol levels over 12 weeks. The current status of this study is unclear, and it plans to enroll 150 participants.

Study design
This is an interventional study, meaning participants will receive a specific treatment. It plans to enroll 150 participants, but the phase and whether it's blinded (participants don't know which treatment they receive) are not specified.
What's involved
Your participation will involve up to five in-person visits over about 13 weeks, including a screening, medication pickup, midpoint, experimental lab session where you'll be offered alcohol, and a final follow-up. You will take a study medication daily for 8 weeks, complete daily surveys, and have weekly virtual check-ins.
Compensation
Not stated in the trial record.
Follow-up
Participants will be followed for changes in drinking behavior and alcohol levels for up to 12 weeks.
