This stat beggars belief. I think the headline is phrased incorrectly, and the overall stat is misleading. The actual stat is only from dead drivers who were tested for THC.

    Researchers analyzed coroner records from
    Montgomery County in Ohio from January 2019
    to September 2024, focusing on 246 deceased
    drivers who were tested for THC following a
    fatal crash. When autopsies are performed,
    drug screening is typically part of the
    process.

The unanswered and unaddressed questions here are, how often and why were the THC tests administered? The article says that’s standard for autopsies. But how often are autopsies conducted on deceased drivers? I would be truly surprised if it’s 100%. In fact, I would expect it to happen only in cases where there was some suspicion of intoxication. In which case, this finding isn’t very surprising after all.
