What you need to know

After alcohol, cannabis is the second most used substance in Canada. There’s a higher risk of traffic collisions and car-crash deaths among young drivers, aged 16-19. It was reported that a large portion of these fatalities were related to alcohol in 2012. Evidence shows that many youth engage in risky passenger behaviour such as getting into a car with a driver who has consumed alcohol or cannabis. However, it’s important to note that there is still some debate about whether driving after using cannabis is related to car accidents and deaths.
