Cannabis: Legal, but Prohibited While Driving

Cannabis is now legal, but you are still prohibited from driving after having consumed it.

The Very Real Effects on Driving

Cannabis affects the brain and impairs your ability to drive. It causes a decrease in vigilance and concentration, slower reflexes, poor coordination, longer reaction times, and impaired judgment. Estimates indicate that driving under the influence of cannabis doubles your risk of being involved in a traffic accident.

  • Failure to notice road signs
