Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The investigators hypothesize that:
1. Participants who receive the full personalized feedback intervention will be less likely to report risky cannabis use at 3- and 6-month follow-ups compared to participants who receive educational materials only (Primary Hypothesis).
2. Participants who receive the full personalized feedback intervention will report greater reductions in their perceptions of how much others use cannabis at a 3-month follow-up compared to participants who receive educational materials only.
3. Reductions in perceptions of how much others use cannabis at 3-month follow-up will be positively associated with reduction in the participant's risky cannabis use at 6-month follow-up.
A 2-arm parallel group randomized controlled trial will be conducted to test these hypotheses with follow-ups occurring at 3 and 6 months after randomization. Online media advertisements will be used to recruit people currently using cannabis. The advertisements will be placed across Canada using locations found successful in previous trials to rapidly recruit participants (e.g. Google AdWords).
