how did beliefs and perceptions about e-cigarettes change after national news coverage of the EVaLI outbreak?

Introduction
Exposure to media content can shape public opinions about tobacco. In early September
2019, the outbreak of e-cigarette, or vaping, product use–associated lung injury (EVALI)
became headline news in the United States.
Methods
In August and September 2019, we conducted two cross-sectional online surveys with current
and former smokers assessing attitudes and beliefs about e-cigarettes. Study one (n =
865) was collected before the EVALI outbreak was widely covered and study two (n = 344)
was collected after the outbreak had become nation-wide news. We examined differences
in perceptions and beliefs between time points.
Results
E-cigarette harm perceptions increased between study one (mean = 2.67) and study two
(mean = 2.90, p < .05). Ever-users of e-cigarettes largely account for this change. Endorsement
of the belief that e-cigarettes were risky and more likely to cause lung damage compared
to cigarettes increased between studies (p < .05). Seventy eight percent of
participants at study two were aware of the vaping illness story. Being aware of the story
was associated with more endorsement of the belief that e-cigarettes were risky to use, but
not that using e-cigarettes would make the participant more likely to get damaged lungs.
Discussion
When the stories about the health and safety of tobacco products dominate the public information
environment, it presents an opportunity to change beliefs that are frequently targeted
by paid health campaigns. Changes in participant’s perceptions of e-cigarettes were associated
with coverage of this large news story, underscoring the importance of working to
ensure that coverage is a scientifically accurate as possible.
