It’s not safe
- Just as it is not safe to drive after drinking alcohol, it is not safe to drive after using cannabis.
- Research shows that cannabis impacts motor skills, alertness, attention, judgement, decision making skills, and the ability to respond quickly.
It can double your risk of a crash
- Driving after using cannabis can double your risk of being in a crash. Driving high puts you, your friends, and the public at risk.
- Make sure you plan ahead and have a designated driver, call for a ride, call a cab, or stay over.
- It is illegal to drive under the influence of alcohol, cannabis, or other drugs.
- This applies to all vehicles, including cars, trucks, boats, snowmobiles, and off road vehicles.
- In Ontario, there is zero tolerance (you cannot have any cannabis in your system) for young, novice and commercial drivers.
