Background: The FDA is proposing regulating e-cigarettes as tobacco products. Research suggests a link between perceptions about FDA regulation and product safety beliefs. We examined whether knowledge of FDA regulations and perceived harms of e-cigarettes predict public support for restricting vaping in public venues.

Method: Online survey of a nationally representative sample of 960 adults. Using structural equation modeling, we analyzed the relationship between knowledge about FDA regulations of e-cigarettes (e.g., “for safe use”) and support for restricting vaping in public venues (restaurants, bars/casinos/clubs, and parks). Mediators were perceived harms of e-cigarettes (harmful to one’s health, impact of breathing vapors, and e-cigarettes harms compared with regular cigarettes). Analyses were weighted to the U.S. adult population and adjusted for demographic covariates.

Results: About 15% of respondents thought the FDA regulates e-cigarettes, 19-21% accurately reported no FDA regulation, and the remainder did not know. Responding that FDA does not regulate e-cigarettes for safe use (B=0.27, p=0.001) predicted significantly increased support for vaping restrictions compared with responding that FDA regulates e-cigarettes. Concerns about the health impact of breathing in vapors mediated this relationship—those who said the FDA does not regulate e-cigarettes for safe use were more concerned about the impact on their health of breathing in vapors, which was in turn associated with increased support for restricting vaping.  

Conclusion: Incorrect knowledge about regulations of e-cigarettes may undermine support for restricting vaping in public venues. The findings suggest a need to provide publicly accessible, accurate information about the regulatory status of e-cigarettes.

Learning Areas:

Public health or related laws, regulations, standards, or guidelines
Public health or related public policy
Public health or related research
Social and behavioral sciences

Learning Objectives:
Describe the prevalence of public awareness of FDA regulations of e-cigarettes for safe use and for helping smokers to quit smoking. Analyze the relationships between knowledge of FDA regulations of e-cigarettes and public support for policies that restrict e-cigarette use in public venues. Examine whether the relationships between regulatory knowledge and support for policies to e-cigarette use in public are mediated through perceptions of e-cigarette harms. Discuss the implications of these findings on public communication efforts to improve accurate knowledge of the regulatory status and safety profile of e-cigarettes.
