CADCA along with its Geographic Health Equity Alliance is proud to present this installment of its Research Into Action webinar series on Friday, January 15, 2021 at 1 pm EST featuring Dr. Matthew Rossheim discussing his recent article, “Aerosol, vapor, or chemicals? College student perceptions of harm from electronic cigarettes and support for a tobacco-free campus policy”, which was published in Journal of American College Health in 2020. Dr. Rossheim will discuss his and his colleagues’ article’s findings regarding perception of harm of secondhand exposure to e-cigarette emissions and support for tobacco-free campus policies among college students. The article found that use of “chemicals” or “aerosol” instead of “vapor” to describe secondhand e-cigarette emissions in health communications was associated with increased odds of perceiving secondhand exposure to e-cigarettes as harmful. The article also found that greater perceived harm of secondhand exposure to e-cigarettes was associated with increased odds of support for tobacco-free campus policy. Dr. Rossheim will discuss how coalitions can frame their health communication campaigns to influence public opinion on risk perception and policy options.
