Lower-THC, higher-CBD cannabis to help people cut down on drinking
Alcohol Use Disorder and Cannabis: Testing Novel Harm Reduction Strategies
['FUNDING_R01'] · UNIVERSITY OF COLORADO DENVER · NIH-11374863
This project compares switching from high-THC cannabis to low-THC, high-CBD products to see if it helps people with alcohol use disorder reduce or stop drinking.

What this research studies
If you join, you'll be invited because you have alcohol use disorder and currently use high-THC cannabis and want to cut down or quit drinking. You'll be supported to switch to low-THC, higher-CBD cannabis products and followed over time for alcohol use, cravings, anxiety, and biological markers. Your outcomes will be compared to people who continue their usual cannabis use or receive standard care to see which approach leads to better reductions in drinking. The team will use questionnaires, biological samples, and behavioral measures to track changes.
Who could benefit from this research
Good fit: Adults with alcohol use disorder who currently use high-THC cannabis and want help reducing or stopping alcohol use are the ideal candidates.
Not a fit: People who do not use cannabis, are not trying to reduce drinking, or have medical reasons to avoid cannabis are unlikely to benefit from this approach.
Why it matters
Potential benefit: If successful, this could give people with alcohol problems a safer harm-reduction option and guide clinicians on how to talk about cannabis when helping patients reduce drinking.
How similar studies have performed: Previous evidence is limited and mixed, so this harm-reduction approach is relatively novel with only preliminary support from small studies.
