Driving high is driving impaired
CAA has worked for decades to raise awareness about the dangers of driving impaired. Since the legalization of cannabis in Canada in 2018, CAA has also shared important messages about cannabis-impaired driving.

Don't take a chance, even if you feel fine
There’s a common misconception that cannabis can make you a better driver. The reality? Cannabis impedes your reaction time, coordination, spatial awareness, attention span and decision-making ability.
1 in 5 Canadians at risk
20% of Canadians reported to CAA that they have either driven high or been a passenger with a driver who was high. Impaired driving—whether cannabis or alcohol—is a main cause of vehicle accidents, injury and fatalities in Canada.
Young people and cannabis
According to CAA, young people—those aged 16–24 years old—have the highest rates of cannabis-impaired driving, with 50% of young adults and 37% of older teens reporting cannabis consumption.
Edibles and driving don't mix
Ingesting cannabis slows reaction time and impairs driving ability. Edibles are metabolized in the digestive system, so effects are delayed and can last much longer—sometimes up to 12 hours.

Make a plan: If you consume an edible, don't drive. Arrange a rideshare, choose a designated driver, or plan to stay home.
-
Be aware of how cannabis impacts reaction times: Although cannabis impairs your cognition, the delayed onset of effects leads consumers to overestimate control over their bodies.
