New CAA-supported research from the University of Saskatchewan is raising concerns about how cannabis edibles affect young drivers — particularly those aged 19 to 30, the group with the highest crash rates in Canada.
The study tested 50 drivers and found significant deficits in reaction time, lane discipline and speed control after consuming edibles. Impairment was most noticeable 90 minutes after ingestion, even when some participants reported feeling normal.
CAA Community Relations Consultant Michael Stewart highlighted an additional noteworthy finding.
The research also points to a growing trend of poly-use, with 57 per cent of respondents combining cannabis with other substances such as alcohol, painkillers, or psychedelics — further increasing the risk on the road.
Stewart discussed the disconnect between how drivers feel after using edibles and how impaired they actually are.
With holiday gatherings approaching, CAA says the timing of these findings is important, as more young adults may be using edibles in social settings.
Stewart added guidance for road safety during the festive season.
CAA is urging anyone consuming cannabis — especially when combined with alcohol or other substances — to plan a sober ride home and avoid driving impaired.
