Development and Evaluation of HighAlert

Canada103 participantsStarted 2023-11-01

Plain-language 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.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
