Cannabis-impaired driving presents a growing clinical and public safety concern as legalization expands. Clinicians need evidence-based guidance to counsel patients about impairment risks and timing of cannabis use relative to driving, especially given the complex pharmacokinetics of different cannabis products.
Research demonstrates measurable driving impairment with cannabis use, though the relationship between THC blood levels and functional impairment remains complex and less predictable than alcohol. Impairment duration varies significantly by consumption method — smoking/vaping may impair for 3-4 hours while edibles can affect driving ability for 6-8 hours or longer. Individual factors including tolerance, product potency, and co-use with other substances further complicate impairment assessment.
“I tell patients that cannabis affects reaction time and decision-making in ways that compromise driving safety, period. Unlike alcohol, we don’t have reliable biomarkers to predict when someone is too impaired to drive — so the safest approach is planning alternative transportation whenever cannabis is involved.”
