Driving impairment represents one of the most immediate safety concerns as cannabis legalization expands, yet clinical guidance remains fragmented due to inconsistent research methodologies and detection challenges. Unlike alcohol, cannabis impairment cannot be reliably measured through simple roadside testing, creating both legal and clinical assessment gaps.
Current research demonstrates measurable psychomotor impairment from acute cannabis use, particularly affecting reaction time, lane tracking, and divided attention tasks. However, impairment timing varies significantly based on consumption method, THC concentration, individual tolerance, and concurrent medications. Detection challenges persist because THC blood levels correlate poorly with functional impairment, and metabolites can remain detectable long after psychoactive effects have resolved.
“I counsel patients that any amount of THC can potentially impair driving ability, but the ‘when it’s safe’ question remains genuinely difficult to answer with precision. The safest clinical recommendation remains avoiding driving for several hours after any cannabis use, recognizing this varies considerably by individual and product.”
