Why don’t doctors understand medical marijuana was a question put to cannabis experts Drs. Samoon Ahmad and Kevin Hill in a fascinating interview done by Paxton Quigley. Dr. Ahmad, a psychiatry professor at New York University’s Grossman School of Medicine, said that a large part of the problem is due to the fact that there has been no real discussion of medical marijuana and the endocannabinoid system in medical schools over the past several decades. He lamented that the situation continues today although attitudes are slowly changing.
