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.
This Evidence Brief identifies risk factors associated with simultaneous alcohol and non-medical cannabis use. These can then be used to potentially highlight populations or groups who may be at increased risk for this behaviour.
This Evidence Brief explores potential links between cannabis production odours and health effects.
This Evidence Brief addresses three questions:
1. What is the prevalence of DUIC in Ontario and Canada?
2. In jurisdictions where new cannabis legislation was introduced, did the prevalence of DUIC change following the change in legislation?
3. Does DUIC increase the risk of motor vehicle collision as compared to driving sober?
To better inform interventions to prevent driving under the influence of Cannabis, this Evidence Brief asks two questions:
1. What are risk factors for cannabis-impaired driving?
2. What interventions have been shown to prevent or reduce DUIC?
