Cannabis Product Labeling and Marketing Study

This study is looking at how different labels (like "Sativa" or "Indica") and marketing claims (like "energizing" or "sedative") on cannabis products affect how people think about them. Researchers want to understand if these labels and claims change your perceptions of harm, what effects you expect, and if you'd be willing to use the product. You can join if you are 21 or older, live in a US state where recreational cannabis is legal, and have used cannabis before (either a few times or more regularly). Success for this study means understanding how these marketing strategies influence users' perceptions and intentions. The current recruitment status is unclear, but the study plans to enroll 2000 participants.

What's involved
You would answer online survey questions about your perceptions of a cannabis product advertisement.
Compensation
