Associations Between Exposure to Cannabis Advertisements and Frequency and Severity of Cannabis Use in Older Adolescents

Sep 27, 2022


Youth and Cannabis Advertisements

In a national survey study with 20 legal cannabis states among youth (ages 16-20), we examined whether greater scores on a cannabis advertisement exposure index varied between types of jurisdiction (med- only vs. nonmedical states) was associated with greater odds of past-week cannabis use prevalence and cannabis use disorder (CUD). No associations were found between the cannabis advertisement exposure index and past-week use status in youth for either jurisdiction. However, CPPC found that in medical-only states (not adult use states), greater advertisement exposure was associated with greater odds of CUD even when controlling for other relevant variables. These findings were strengthened after a Z- score test was used to find that more frequent exposure to cannabis advertisements was more strongly correlated to problematic cannabis use in medical-only states (r=.38, p <.01) than adult use states (r=-.002, p=.98).
These findings suggest that exposure to cannabis advertisements may present greater risk for CUD in states with medical-only cannabis laws, and suggest that further research is needed to examine the impacts of cannabis advertisements on youth across fully legal, medical, and illegal states.

In September 2023, New York State Department of Health (DOH) issued a Request for Information (RFI) regarding methodologies and technologies used for the detection and assessment of driving under-the-influence of cannabis (DUIC). The RFI purpose is to assist the DOH in assessing the current state of research on impairment due to cannabis ingestion, and to review current devices that can be used to detect impairment. Moreover, the DOH is seeking to identify research institutions in higher education that are currently performing this type of research.
