Reduced-Risk Warnings Versus the US FDA-Mandated Addiction Warning: The Effects of E-Cigarette Warning Variations on...

Area of Science:

• Public Health
• Risk Communication
• Tobacco Control

Background:

• Electronic cigarette (e-cigarette) warnings have historically focused on addiction risks.
• Reduced-risk warnings are emerging as a potential communication strategy for e-cigarettes.
• Understanding perceptions of different warning types is crucial for public health messaging.

Purpose of the Study:

• To compare perceptions of e-cigarette health risks based on addiction warnings versus reduced-risk warnings.
• To evaluate the believability, comprehension, and clarity of different e-cigarette warning types.
• To inform future e-cigarette warning label policies.

Main Methods:

• A between-subjects experiment involving 672 participants (smokers, e-cigarette users, dual users, nonusers).
• Random assignment to one of three warning conditions: FDA addiction warning or two reduced-risk warnings.
• Assessment of health risk perceptions, believability, comprehension, and clarity of risk communication post-exposure.

Main Results:

• The FDA addiction warning was perceived as more believable and easier to comprehend than reduced-risk warnings.
• Overall and addiction-specific risk perceptions were higher with the addiction warning.
• Specific disease risks (cancer, heart disease, lung disease) were perceived as greater with reduced-risk warnings.

Conclusions:

• The FDA addiction warning is more effective for general risk and addiction perception.
• Reduced-risk warnings may be more effective in communicating specific disease risks associated with e-cigarettes.
• Findings highlight the nuanced impact of different warning types on public perception of e-cigarette risks.
