Facts and Statistics
Researchers estimate that drugs are present in four out of 10 fatally injured drivers on Canadian highways.
A 2017 study of Canadian deaths by the Traffic Injury Research Foundation found that in 2012:
- More than 39 per cent of drivers who died tested positive for drugs.
- Almost 20 per cent who died tested positive for marijuana.
The study also noted that while the presence of alcohol in drivers killed in motor vehicle collisions is dropping, the presence of drugs appears to be increasing. See the study.
2016 Manitoba Roadside Survey Results
Ten per cent of drivers who participated in the voluntary 2016 Roadside Survey in Manitoba tested positive for drugs. See more information.
About 70 per cent of Canadians believe taking marijuana before driving is very or extremely dangerous – about the same as for drinking and driving, or driving while talking on a hand-held phone.
However, some drivers (young adults in particular) do not have a clear understanding about the impacts of marijuana on driving. One in four adults 18 to 34 years of age feel that the ability to drive is the same or better after taking pot, according to a survey by the Canadian Council of Motor Transport Administrators. However, evidence clearly shows that drugs, including marijuana, impair driving ability.
