Medical Cannabis Use Doesn’t Adversely Impact Substance Abuse Treatment Outcomes, Study Says

Arcata, CA: The physician-supervised use of medical marijuana does not adversely affect the outcomes of individuals enrolled in substance abuse treatment programs, according to clinical trial data published last week in the Harm Reduction Journal.

An investigator at Humboldt State University in California assessed whether medical cannabis use was associated with negative outcomes in patients referred to a substance abuse treatment program.

The study reported that treatment outcomes for medically authorized cannabis users were comparable to those of subjects who were not supervised to use the drug.

“Cannabis use did not seem to compromise substance abuse treatment amongst the medical marijuana using group, who (based on these preliminary data) fared equal to or better than non-medical marijuana users in several important outcome categories (e.g., treatment completion, criminal justice involvement, medical concerns),” the study concluded. “This exploratory study suggests that medical marijuana … may not adversely affect positive treatment outcomes.”
