Drugged Driving: Take it seriously. Respect the effect.
Driving even
a little high can wreck you.
Cannabis and driving don’t mix! Being even a little high behind the wheel can wreck you—protect yourself and others on the road.
How does cannabis influence my driving?
Cannabis affects areas of the brain that control balance, coordination, memory, and judgment.1 On the road, this can result in slower reaction time, decreased ability to concentrate and make decisions, and reduced awareness of time and distance, which are critical for safe and alert driving.
How long should I wait to drive after using cannabis?
Research suggests waiting six hours after using cannabis before driving.2 However, effects from edibles can be delayed, and last up to 12 hours. If you’ve mixed cannabis with other substances like alcohol, plan to wait even longer before driving. Remember—if you feel different, you drive different.
Can I get a DUI?
Yes. Using cannabis while driving (by a driver or passenger) and driving under the influence of cannabis is against the law. If you are impaired while driving, you can get a DUI — even as a certified patient with a medical card.
What else should I know?
No matter what you may have heard, cannabis is a drug with impairing effects — it doesn’t make you laser-focused or a better driver. Driving even a little high is never as safe as driving sober.
It’s not just you on the road.
If you’re going to consume cannabis, stay at home, or make a plan for a safe and sober driver, every time! Protect yourself and others—let’s keep Maryland safe!
