Cannabis-impaired driving may not be new, but has come to the forefront with legalization. CAA wants you to have the information to make safe decisions for yourself and your loved ones.
Research into effects of cannabis on driving
Young Canadians are more at risk of a vehicle crash even five hours after inhaling cannabis, according to results of a clinical trial conducted at the Research Institute of the McGill University Health Centre (RI-MUHC) and McGill University, and funded by the Canadian Automobile Association (CAA).
The research found that performance declined significantly, in key areas such as reaction time, even five hours after inhaling the equivalent of less than one typical joint. The participants’ driving performance, which was tested in a driving simulator, deteriorated as soon as they were exposed to the kinds of distractions common on the road.

False. Police officers across Canada can administer roadside tests to check for impairment. These can include testing devices or calling in specially trained drug recognition officers.
I’m not going far so it’s okay
