2/15/2010 - An excellent review of clinical studies on the medical use of cannabis and cannabinoids has been published by Arno Hazekamp and Franjo Grotenhermen. The authors summarize 37 different controlled studies in the period July 1, 2005 - August 1, 2009. Eight specifically involved smoked marijuana, all of which indicated medical efficacy. Conditions treated included chronic pain, HIV neuropathy, spinal cord injury, and Hep C. The authors add that at least 110 studies on medical cannabis have been published since 1975. So much for the notion that our drug bureaucrats need more studies on medical marijuana. Read the study.
