More Ontario drivers using cannabis behind the wheel: study

That’s the finding of a new CAA study, which also found drivers don’t think driving high is as bad as being drunk

  • New CAA study finds 19% of Ontario drivers used cannabis and then drove, a 5% increase from last year
  • More than 90% of drivers think cannabis-impaired driving isn’t as bad as drunk driving
  • And more than three-quarters of those using cannabis were confident they were able to drive

The study found that 52% of cannabis-impaired drivers got behind the wheel within three hours of consumption; and that 31% of drivers “reported feeling high while driving,” and 63% were concerned about getting caught. On top of that, 76% of drivers using cannabis “expressed confidence in their ability to drive.”

Of those who drove after using cannabis, 32% said they did because they didn’t think they’d consumed a significant amount; 32% had no alternative to getting home; and 28% did so because “the drive would be short anyway.”

Drivers obviously aren’t unaware of the issue, as 91% said they believe driving while impaired by cannabis is a “serious risk to road safety,” a concern that’s even higher among older drivers. However, when comparing cannabis impairment to other intoxicants, 95% said drunk driving is more dangerous, and 93% said impairment from illegal narcotics or opioids is worse than weed.

In Ontario, 74% of drivers have at least one cannabis store in their neighbourhood, up 14% from 2023; and 35% have four or more stores nearby, a 6% increase from last year.

“There is often a misconception on the effects cannabis can have on a driver,” said Michael Stewart, community relations consultant for CAA SCO. “However, it has been proven that driving impaired (on cannabis) can greatly impact a driver’s reaction time, coordination, and decision-making, just the same as it does when consuming alcohol. Cannabis can be safely consumed recreationally, but never when behind the wheel.”
