Overview
Brief Summary
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.
Detailed Description
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.

Outcomes
Primary Outcomes
Product appeal score
Time Frame: Minute 1
One item to assess the appeal of the product. Results will be reported as means. Question: How appealing is this edible to you? Response options: (0) Not at all appealing to (10) Very appealing. Higher score denoting more appeal
Perception of product safety score
Time Frame: Minute 1
One item to assess the participants' perception of the safety of the product. Results will be presented as the frequency of each type of response. Question: How safe do you think it would be to eat this edible? Response options: (1) Not at all safe, (2) Slightly safe, (3) Somewhat safe, (4) Moderately safe, (5) Very safe. Higher score denoting more safe to eat
Perceived likelihood of experiencing unwanted effects score
Time Frame: Minute 1
One item to assess the participants' perception of the likelihood of experiencing unwanted effects. Results will be presented as the frequency of each type of response. Question: How likely are you to experience unwanted effects if you eat this edible? Response options: (1) Not at all likely, (2) Slightly likely, (3) Somewhat likely, (4) Moderately likely, (5) Very likely. Higher score denoting greater likelihood of experiencing side effects
Interest in a free sample score
Time Frame: Minute 1
One item to assess how interested a participant would be in a free sample of the product. Results will be presented as the frequency of each type of response. Question: How interested would you be in a free sample of this edible? Response options: (1) Not at all interested, (2) Slightly interested, (3) Somewhat interested, (4) Moderately interested, (5) Very interested. Higher score denoting more interest
Concern about the risks of overconsumption due to warning score
Time Frame: Minute 1
One item to assess how much the warning makes the participant concerned about the risks of overconsumption for participants randomized to view a package with a warning (intervention conditions only). Results will be presented as the frequency of each type of response. Question: How much does this warning make you concerned about potential risks from eating too much of this edible? Response options: (1) Not at all, (2) A little, (3) Somewhat, (4) Quite a bit, (5) A great deal. Higher score denotes more concern
Improved understanding of safe consumption due to warning score
