Legal cannabis is often blamed for rising traffic deaths, but federal data tells a more complicated story. NHTSA findings, toxicology limitations, and conflicting crash studies reveal that THC presence is not a reliable measure of impairment. This investigation breaks down how flawed testing and policy shortcuts have shaped the narrative around so-called stoned driving.
THE CANNABIS LIE is a reporting series examining how cannabis policy turns shaky assumptions into hard penalties. In THE CANNABIS LIE: Vol. 2, The Fiction of Impairment, THC detection is often treated like proof of impairment, even though blood levels show a weak, inconsistent relationship to functional driving ability. This installment explains why per se THC limits and zero tolerance rules create false certainty, why urine metabolites only show prior exposure, and why real impairment should be demonstrated through behavior and context, not presumed from a lab result.
