• Registration Number: NCT06098573
• Lead Sponsor: Western University, Canada

Brief Summary

In Canada, youth ages 16-24 have the highest rates of cannabis use, impaired driving, and express the least concern for driving under the influence of cannabis (DUIC). As such, developing effective and practical DUIC prevention efforts is crucial. This study aims to evaluate the effects of 'High Alert' in reducing 3-month risky cannabis use and DUIC among young Ontarian drivers. 'High Alert' is an interactive web-based smartphone application developed by the research team with the feedback of experts and youth. 'High Alert' modules focus on recognizing what constitutes risky cannabis use, the effects of cannabis on driving, the risks of DUIC, and strategies to avoid DUIC. A pilot randomized controlled trial will compare the effects of 'High Alert' with an active control (DUIC Information) and passive control (no contact). Overall, effectively preventing DUIC among youth is critically needed and time-sensitive.
