As of 2015, about 22 million individuals in the United States reported using cannabis / marijuana in the last month (1). In 2011, almost 70 million Americans reported binge drinking in the last month ( binge drinking defined by the survey as 5 or more drinks on one occasion) (2).
Some individuals may consider marijuana use as they are reducing alcohol use. A recent study looked at how cannabis use might impact alcohol use.
What was the study? (3)
1,383 newly abstinent alcohol dependent individuals were participating in a multi-site randomized control trial for treatment options of alcohol use disorder in the landmark COMBINE study (4-5).
Researchers compared alcohol use among those who used cannabis versus those who did not use cannabis.
What were the study results?
The authors (3) found that compared to no cannabis use, ANY cannabis use during treatment for alcohol use disorder was related to LESS alcohol abstinence at end of treatment.
They found that each additional day of cannabis use was associated with approximately 4–5 fewer days of abstinence from alcohol (3).
In this study, cannabis use impacted how often the participants drank, but not how many drinks they had (3).
Further study in this area is needed.
What does this mean?
This study suggests that it may not be a good idea to use cannabis if you are trying to abstain from alcohol.
What are some useful resources regarding cannabis?
