Perceptions of Proposed Warnings for Cannabis Edibles Packaging

The purpose of this study is to compare a delayed-effects warning to an expanded warning developed in previous experiments on knowledge, harm perceptions, and willingness to try cannabis edibles. Additionally, this study will examine the effects of a corresponding icon on attention to and recall of the warning.

Cannabis edibles are rapidly leading the legal recreational cannabis market. The Cannabis edibles present health harms that are not typical of smoked marijuana, including accidental overconsumption of high levels of THC. One effective way to communicate proper dosing and risks of overconsumptions is through package warnings. This experiment will assign participants to view real cannabis edibles packaging with one of four variations of warnings and a series of questions to assess knowledge, harm perceptions, and willingness to try the product shown. One group of participants will serve as the control and will see the same cannabis edibles packaging without a warning.
