Some things just shouldn’t mix.
Driving and cannabis is not a good combo. Instead, when you consume a cannabis product, mix in a cozy couch or a sober friend for a safe ride home. Cannabis can cause a slowed reaction time and trouble concentrating, and those are not side affects you want to experience behind the wheel.
Never drive impaired.
The effects of cannabis may be delayed when consuming cannabis edibles, and the side effects can be different for each person.
If you consume alcohol or cannabis, do not get in the driver’s seat. Like drunk driving, driving after consuming cannabis is unsafe, and it is a crime.
For wherever you need to go, always have a safe ride and a sober driver.
Driving while impaired by drugs, including prescription and non-prescription medications, is illegal in Canada.
Drivers found guilty of drug-impaired driving face the same penalties as those convicted of alcohol-impaired driving.
Cannabis
Cannabis use compromises reaction time and the ability to make safe decisions on the road. While cannabis is now legal to use in Canada, it is illegal to drive if you’re impaired by THC. It’s also illegal to:
- Consume cannabis in or on a vehicle while on a public roadway, whether the vehicle is in motion or not.
- Transport cannabis in or on a vehicle, unless stored in a secure compartment such as your vehicle’s trunk.
Drivers convicted of these offences will move down on the DSR scale. Please use responsibly. Learn more about the dangers of driving after using cannabis.
Prescription drugs
It’s important to understand how your prescribed medications affect your ability to drive. If you drive while impaired by prescribed medication, you can be charged with impaired driving. Discuss the possible effects of any medication with your doctor or pharmacist. Learn more.
Illegal drugs
Illicit drugs are harmful and dangerous. They may cause hallucinations, hostility and aggressiveness in addition to dulling normal thought processes and impairing motor skills. If you are found to be driving while under the influence of illegal drugs, you will be charged with impaired driving and may face other severe consequences. Learn more about the effects of drugs.
Mixing drugs and alcohol
It’s important to note that combining drugs and alcohol can amplify the effect of each substance, even in small quantities. If you mix drugs with alcohol, do not drive.
The penalties of driving high
In the eyes of the law, drug-impaired driving is the same criminal offence as alcohol-impaired driving. In Manitoba, all drivers suspected by police of being under the influence of any drug can receive an immediate 24-hour roadside licence suspension.
If you fail a drug recognition evaluation, you are subject to an immediate Tiered Administrative Licence Suspension, which ranges from 72 hours to 60 days. You can face more severe penalties, depending on the amount of drugs in your system. See more information on the penalties you can face for driving under the influence of drugs.
If you take any drugs, including cannabis or prescription medication, don’t drive. Plan ahead to get home safely. If you or someone you know is struggling with addiction, please visit the Addictions Foundation of Manitoba website.
