Brief Summary

This discrete choice experiment (DCE) study aims to address gaps in cannabis packaging regulatory research by testing how variations in cannabis packaging and health warning design impact reactions to packaging and intentions about cannabis use. The goal of this work is to identify the most effective combination of health warning features to improve consumer awareness of cannabis health risks. Establishing criteria for cannabis products in the US is critical because inconsistent state guidelines have resulted in contradictory policies in legal retail states, arguably leading to increased hazardous use and failure to meet public health standards. The contributions of this study's outcomes are expected to be significant because they will benefit public health as cannabis becomes available in legal retail markets and regulatory and governmental agencies seek effective ways to communicate cannabis risks to the public.

Eligibility Criteria

Eligibility for participation includes: 1) being 21 years of age or older, 2) being able to speak and understand English, 3) self-reported having consumed cannabis in the last 30 days (any mode, e.g., flower, vape, edible, etc.), and 4) residing in a U.S. state or jurisdiction where retail (i.e., non-medical) cannabis use is legal.
