Large review finds medicinal cannabis rarely aids mental health and raises side-effect risk
A comprehensive analysis of 54 randomized trials (2,477 participants) finds medicinal cannabis provides little to no benefit for depression, anxiety, PTSD and other mental health disorders, while adverse effects are about 75% more likely. Some signals for cannabis use disorder, insomnia, Tourette’s, and autistic traits were noted but of low quality. The researchers caution against routine medicinal cannabis for mental health, noting it can delay proven treatments, and acknowledge cannabis has established benefits for epilepsy, multiple sclerosis, and certain types of pain.
