Cannabis and Driving in Older Adults
Question: What is the association between retail cannabis available to the consumer, driving, and associated blood tetrahydrocannabinol (THC) levels in people over 65 years of age?
Findings: In this cohort study, 31 regular users of cannabis aged 65 to 79 years chose on average high potency (18.74% THC) THC-dominant cannabis. Weaving was increased and speed was decreased at 30 minutes after smoking, which was not correlated with blood THC concentrations; subjective experience and self-reports of impaired driving persisted for 3 hours.
Meaning: These findings suggest that older drivers, even if they regularly use cannabis, show evidence of impaired driving performance after smoking cannabis
