Could cannabis help people beat drug addiction? New research suggests it might.
In a groundbreaking study, researchers from the University of British Columbia (UBC) have found that medical cannabis could be a valuable tool for individuals struggling with substance use disorders. The findings reveal that regular use of prescribed cannabis products may help reduce cravings and support long-term recovery, particularly among people dealing with opioid, stimulant, and alcohol dependencies.
Published in the Harm Reduction Journal, the study followed nearly 300 patients over six months at a Vancouver-based addiction treatment program. These participants were prescribed cannabis to manage various conditions, including chronic pain and insomnia—common barriers to recovery.
The researchers observed that patients who took cannabis at least weekly were more likely to remain in treatment and reported fewer cravings for other, more harmful substances. Many also noted improved mental health and sleep patterns—factors that can significantly affect relapse rates.
“Medical cannabis appears to offer therapeutic benefits that help stabilize patients during early recovery,” said Dr. M-J Milloy, the study’s lead investigator and a research scientist at UBC and the BC Centre on Substance Use. He added that while cannabis isn’t a cure-all, it may serve as a harm-reduction tool for those who have not responded well to traditional treatments.
The findings come amid a growing opioid crisis in North America and mounting calls for alternative strategies to combat addiction. Still, experts caution that more research is needed. This study was observational, meaning it couldn’t prove cause and effect, and the researchers relied on self-reported data.
Even so, the evidence adds to a small but growing body of research suggesting cannabis might have a role in supporting recovery, particularly when used under medical supervision.
