Recent publications & press coverage on MAC Lab team research
cj.janssenWith co-directors Dr. Stacey Hust and Dr. Jessica Willoughby at the helm of the MAC Lab team’s efforts, two studies have recently been published in academic journals! Both studies draw upon data regarding teens’ and young adults’ perceptions of edible cannabis product packaging elements. Take a look below for a round-up of these publications, including press coverage of this important health communication research:

- The Journal of Health Communication published a qualitative study led by Dr. Hust, which analyzed 28 Washington teens’ (ages 13 – 17) thoughts and perceptions on the designs of cannabis-infused edible product packaging. Notable findings indicate that teens find such packaging to be appealing due to the presence of bright colors, fun imagery, and lifestyles (such as being vegan, for example) that appeared to be promoted by the packaging. Interestingly, teens who had both pre-existing knowledge of cannabis and were literate in cannabis product information expressed skepticism towards such packaging.
- The results of this work indicate the need for policymakers and health educators alike to consider the perspectives of teenagers in regulatory processes regarding cannabis products.

- Most recently, a study led by Dr. Willoughby was published by the Drug and Alcohol Review. Qualitative focus groups were conducted with teens across Washington state to learn more about how they perceive warning labels on cannabis edible packaging.
- The team found that teens may not find cannabis edible warning labels to be particularly relevant to them, feeling that such information pertains more to younger children. Additionally, teens feel that packaging designs often hide warning labels; bearing this in mind, though, participants expressed that they often pay no attention to any labels on edible product packaging whatsoever, including nutrition labels and serving size recommendations on food and drink packaging that do not contain cannabis.
- The results of this study demonstrate that teens might overlook warning labels on cannabis edibles packaging either a) intentionally, as they don’t feel the labels apply to them, or b) unintentionally, because they may be unfamiliar with cannabis products and how labels provide important information about servings and potency.

The WSU MAC Lab, led by researchers Dr. Stacey Hust and Dr. Jessica Willoughby, recently earned a nearly $670,000 National Institutes of Health Grant to fund an intervention aimed at reducing cannabis misuse.

On Jan. 31, MAC Lab Co-Directors Stacey Hust and Jessica Willoughby presented at the 6th Annual Cannabis Action Conference. Dr. Hust and Dr. Willoughby presented on the results of a state-wide survey of teens and young adults about cannabis product packaging and implications for prevention. The session was titled Examining cannabis edibles packaging: Findings from a survey of Washington State youth.


Drug and Alcohol Review describes a MAC Lab experiment on the inclusion of sexualized appeals in cannabis advertising. The research team conducted an online experiment with college students in Washington state, showing participants brand-generated cannabis social media ads that included either images that contained sexual objectification of women or recreational appeals. Exposure to sexualized ads was associated with increased perceptions of cannabis sex enhancement scripts and increased cannabis sex enhancement expectancies.
