Study reveals persistent THC use among fatal crash drivers

A new study presented at the American College of Surgeons Clinical Congress found that nearly 42% of drivers killed in crashes in Ohio had active THC in their blood, with levels far exceeding legal limits. The prevalence remained unchanged even after recreational cannabis legalization in 2023. Researchers urge stronger public messaging on the risks of driving after marijuana use.
