Cannabis Cuts Alcohol Intake, Study Finds
19 Nov
Summary
- Researchers found participants drank less alcohol after smoking cannabis.
- Adults consumed about a third less alcohol after higher THC cannabis.
- The study took place in a controlled, bar-like environment at Brown University.

In a novel experiment conducted on the campus of Brown University, researchers investigated the effects of cannabis consumption on alcohol intake. The study involved approximately 150 adults who regularly use both substances. Participants smoked research-grade marijuana with varying THC levels, including a placebo, in a controlled environment.
Following cannabis consumption, participants were observed in a makeshift bar setting. The findings indicated a significant reduction in alcohol consumption, with those smoking higher THC cannabis drinking about a third less than when they smoked the placebo. Similar reductions were observed with lower THC cannabis.
This research offers initial insights into the phenomenon of "cross-fading" and arrives amid increasing interest in marijuana and a shift away from alcohol. While promising, the researchers emphasize that these controlled results may not directly translate to real-world scenarios, where cannabis potency and consumption methods differ.
