Medical Marijuana #360

March 11, 2016

This week, we're taking a closer look at the medical marijuana controversy. How effective is medical marijuana and for what conditions is it a suitable treatment? In our attempt to separate evidence from anecdote we're joined by a panel of three: Dr. David Casarett, a palliative care physician and author of the book "Stoned: A Doctor's Case for Medical Marijuana"; Dr. Robert Wolff, a systematic reviewer for Kleijnen Systematic Reviews and coauthor of a recent systematic review to assess benefits and harms of cannabis for medical use; and Dr. Marcel Bonn-Miller, assistant professor in the Department of Psychiatry at the University of Pennsylvania Perelman School of Medicine, who has dedicated his career to understanding the relationship between cannabis use and PTSD.
