Dr. Drew Pinsky, that doctor you probably recognize from television, recently told The Cannabist that marijuana “acts like an opiate and causes severe addiction” and that withdrawal symptoms can include serious mood and sleep disturbances. C’mon, Pinsky. Really? My professional experience — where I worked as a residential addiction counselor and studied cannabis pharmacology in university — tells me differently. And when my Crohn’s Disease was in remission I quit using marijuana and never experienced a single withdrawal symptom.
