Cannabis is one of the most commonly used psychoactive substances in Ontario, along with alcohol and tobacco. Cannabis was legalized for non-medical use on Oct 17th, when it became legal for adults over 19 to use cannabis without a prescription. To address this issue, a webinar series is being hosted by RNAO and CAMH (PSSP) to provide an overview of cannabis use patterns across the lifespan and to address concerns specific to each age group. 

According to the National Cannabis Survey (NCS), 18% of Canadians aged 15 years and older reported using cannabis in the first quarter of 2019. Looking at cannabis users with a valid driver's license, 15% of drivers reported driving within two hours of consuming cannabis.[1] According to the 2017 CAMH Monitor Survey 3% of Ontario adults reported driving within one hour of consuming cannabis.
When asked how long adults should wait before driving after consuming cannabis, 6% of adult Canadians think it is safe to do so within 3 hours, 49% think adults should wait at least three hours, and 45% believe it depends on other factors such as weight or method of consumption.
