Cannabis

Cannabis is the most commonly used substance in Ontario, aside from alcohol and tobacco. When consumed (e.g., smoked or eaten), cannabis products can cause short-term psychoactive effects. Cannabis is used for non-medical, medical and cultural purposes. There is a growing body of evidence on the therapeutic and adverse health effects of cannabis.
