High-on-pot drivers are contributing to more highway accident deaths.
How much social and public-health damage will Americans suffer before doing a U-turn on marijuana promotion? A new study finds that more than 40% of drivers who died in car accidents in one U.S. county over the last six years had elevated levels of the drug in their blood.
Researchers from Wright State University analyzed driver autopsy results from car crashes in Montgomery County, Ohio, between January 2019 and September 2024. More than four in 10 tested positive for pot’s psychoactive ingredient THC, with an average level of 30.7 nanograms. That’s more than six times the level most states use to define impairment.
