Testing Warning Labels for Retail Cannabis Products
This study is testing different designs for warning labels on retail cannabis products. We want to understand how variations in cannabis packaging and health warnings affect people's reactions and their intentions to use cannabis. The goal is to find the most effective health warning features to help consumers understand the risks of cannabis. You may be able to join if you are 21 or older, speak English, have used cannabis in the last 30 days, and live in a U.S. state where retail cannabis is legal. We are looking for about 450 participants. The study is currently unclear on its recruitment status.

What this trial measures
- Risk perceptions about cannabis productsAt the time of survey completion (approximately 15 minutes)
Binary measure using best-worst scaling. For each question, participants will also have the option of indicating none of the above/opt-out as a response. For each choice set, the statement selected as the best option will be coded using a value of 1, and the worst will be coded as -1. The remaining statements in that set will be coded as 0. If the participant selects none of the above, all statements in that choice set will be assigned a value of 0.
