Summary

A new study reveals that over 40% of drivers killed in motor vehicle crashes had active THC in their blood, with levels far exceeding legal impairment limits. The research, to be presented at the American College of Surgeons Clinical Congress 2025, analyzed coroner records from Montgomery County, Ohio, and found that cannabis use before driving remains widespread despite legalization. The rate of THC-positive drivers in fatal crashes did not decrease after cannabis legalization, indicating that policy changes have not altered risky driving behaviors. Experts warn that lack of public awareness about marijuana's dangers while driving continues to put lives at risk.
