Background: Increasing intentions to quit e-cigarettes among youth and young adults can reduce usage rates by making quit attempts more likely. This study assessed the potential impacts of a national media campaign, focused on building knowledge of e-cigarette use risks and cessation resources, on intentions to quit and campaign-targeted beliefs about mental health and quitting.

Methods: A national sample from a repeated cross-sectional online survey was collected from March 2022 to August 2023, among youth and young adults who reported e-cigarette use in the past 30 days (N=5169). Regression models were used to assess associations between weekly campaign awareness and frequency of exposure on intentions to quit e-cigarette use within the next 6 months and targeted beliefs related to mental health and quitting.

Results: Participants who were aware of both cessation and knowledge-building messaging were more likely to report intentions to quit e-cigarette use in the next 6 months (OR 1.43, (95% CI 1.21, 1.69)) and agree with quitting-related targeted beliefs (ORs 1.35-1.63) and a mental health targeted belief scale (b=1.14 (95% CI 0.69, 1.59)), relative those with no messaging awareness. The frequency of exposure to cessation messaging held a dose-response relationship with almost all outcomes.

Conclusion: Findings suggest that frequency and awareness of messaging that educates about e-cigarette harms to mental health and about cessation resources are associated with higher quitting intentions among young people who use e-cigarettes.
