Meta-Analysis Questions Medical Cannabis Efficacy in Mental Health

Initial comprehensive reviews reported minimal efficacy of cannabis-based therapies in treating common mental health disorders. These reviews suggested that medicinal cannabis might not only be ineffective but could also potentially worsen mental health outcomes.

Subsequently, a meta-analysis published in The Lancet Psychiatry by researchers at the University of Sydney reinforced these findings, concluding that current evidence does not support the routine use of medical cannabis for mental health conditions. The study also highlighted concerns regarding the risks associated with such treatments, questioning their overall benefit in clinical practice.
