NCT ID NCT04998006
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This observational study looked at how legal cannabis use changes alcohol drinking habits, gut bacteria, and brain function in people who regularly use both alcohol and cannabis. 77 heavy drinkers who also smoke cannabis took part, providing blood and stool samples and completing thinking and impulse control tasks. The goal was to understand the role of the gut-brain axis in alcohol use, not to test a new treatment.
