Many scientific studies show that cannabis use doubles your risk of being in a car accident. If you have consumed cannabis, it is the safest decision not to drive until the next day.
It is illegal to operate a motor vehicle while impaired by a drug, including cannabis. Persons who do so can be charged and face penalties under the Criminal Code and also receive sanctions, such as driver’s licence suspensions, under the Highway Traffic Act. Drivers who get behind the wheel while high pose a risk of injury or death to themselves and others and could face serious legal consequences.
