Study reports mixed findings on medical efficacy of cannabis
A large-scale review that evaluated the medical efficacy of cannabinoids — the active chemical compounds in marijuana — across a range of conditions found there is moderate evidence to support the use of cannabinoids for the treatment of chronic pain and spasticity in patients with multiple sclerosis. The meta-analysis, led by the University of Bristol and published in the Journal of the American Medical Association, analysed the results of 79 different randomised-controlled studies involving more than 6,400 patients to investigate the benefits and side effects of medical cannabinoids.
