Evidence of Marijuana’s Medical Usefulness Mounts

The current issue of The Journal of the American Medical Association (JAMA) includes two articles that review studies of marijuana’s medical utility and come to similar conclusions about the applications that are best supported by the existing evidence: treatment of chronic pain, neuropathic pain and spasticity.

There is also substantial evidence that THC, marijuana’s main active ingredient, is effective at relieving nausea and restoring appetite.
