简要总结
This study looks at how cannabis product label and marketing claims affect product perceptions, use expectancies, and use intentions among inexperienced and experienced cannabis users. Participants will answer online survey questions on their perceptions of a cannabis product advertisement.
详细描述
This study aims to specify how product label and marketing claims affect product perceptions, use expectancies, and use intentions among cannabis users. A randomized 4 (Sativa, Indica, Hybrid, no strain label) x 3 (energizing, sedative, no claim) online experiment will be conducted with a sample of adults from states that have legalized adult cannabis recreational use. Our main research questions are: (1) Do label and marketing claim affect (a) harm perceptions, (b) subjective effects expectancies (e.g., arousal, sedation), (c) willingness to use, and (d) willingness to use during daily activities (e.g., driving)? and (2) Do label and marketing claim interact to affect product perceptions, use expectancies, and use intentions?
