Age Differences in the Effects of Cannabis on Simulated Driving (NCT04325958)

The Influence of Age on Driving-related Cannabis Effects: Exploring Cannabis Use Frequency and Related Factors

๐ŸŸข Recruiting Observational / Diagnostic ๐Ÿ’Š Investigational Drug / Biologic Sponsor: Centre for Addiction and Mental Health

๐Ÿฉบ Plain-English Summary (8th-Grade Level)

Epidemiological studies suggest that the use of cannabis is associated with an increase in the risk of motor vehicle collisions. It is also known that younger users may be at increased risk for motor vehicle collisions. Further, the frequency with which cannabis is used may be an important variable in determining the effects of cannabis on driving. The purpose of the present study will be to investigate the effects of cannabis on simulated driving in young as compared to middle-aged drivers. Half of the participants will be occasional users of cannabis and half will be frequent users of cannabis.
