Dr. David Saul implies that if patients request a Health Canada cannabis authorization form, physicians are obliged by the provincial medical college to sign the form or refer them to a physician who will. This is incorrect and it is reckless to promote cannabis as a harmless medicine. I have seen patients whose lives have been destroyed by cannabis addiction or cannabis-induced psychosis. Smoked cannabis has been shown to cause precancerous changes in various tissues. Also, THC serum levels rise rapidly when smoked, creating a risk for motor vehicle accidents. The oral and inhaled versions of cannabis are far safer. I would discourage physicians from authorizing smoked cannabis. They should prescribe oral or inhaled cannabis only for patients with a medical condition for which cannabis has been shown to be effective, and who are at low risk for cannabis-related harms.
