Impaired is Impaired
Impaired driving is a serious problem that threatens everyone on the road.
If you’re consuming cannabis, designate a non-consuming driver before you start, call a cab, or get a ride home. Never drive after consuming cannabis. Remember, impaired driving is never OK.
How does Cannabis Consumption Affect Drivers?
Consuming cannabis can seriously impair your ability to drive safely.
Cannabis consumption affects critical driving skills by causing drowsiness and slowing reaction time. It also impairs a driver’s ability to watch and respond to multiple things at once.
Cannabis affects each person differently, but in general, the effects of cannabis can last up to 24 hours.
What defines “impaired”?
The law is very clear on what constitutes impaired driving, and there are three prohibited levels for THC:
- THC levels between 2 and 5 nanograms (ng) per 1 mL of blood are considered impaired.
- THC levels of 5 ng or more per 1 mL of blood carry heavier fines and sentencing.
- Combined alcohol and THC levels are considered impaired at 50 mg or more of alcohol per 100 mL of blood, plus 2.5 ng or more of THC per 1 mL of blood.
To stay safe, always have a plan to get home safely:
- Stay overnight.
- Call for a taxi or rideshare.
- Use public transit.
- Call a close friend or family member.
- Have a designated driver.
