Here we go again. Another week, another massive study by top doctors and scientists finding very limited medicinal value to marijuana. In an age when liberal politicians such as Prime Minister Justin Trudeau and Vancouver Mayor Gregor Robertson claim to be implementing “evidence-based” public policy, I find it odd that they have such a blind spot when it comes to pot.
A new report by the U.S. National Academies of Sciences, Engineering, and Medicine — The Health Effects of Cannabis and Cannabinoids: The Current State of Evidence and Recommendations for Research — that reviewed the results of 10,700 studies on the medicinal qualities of marijuana concluded that there is “conclusive or substantial evidence that cannabis or cannabinoids are effective” in treating only three conditions: chronic pain in adults, chemotherapy-induced nausea and vomiting, and patient-reported multiple sclerosis spasticity symptoms (although there was “limited” evidence of “clinician-measured” spasticity relief).
The report, drafted by a committee headed by Harvard medical school professor Dr. Marie McCormick, reached similar conclusions to a review of the research on medical marijuana published in June by the Journal of the American Medical Association. It found “moderate-quality” evidence that pot controls pain and MS spasticity.
