A 2019 vaping-related health scare reshaped how many smokers view the risks of e-cigarettes – and those perceptions still linger today. New research from MUSC Hollings Cancer Center found that smokers came to see e-cigarettes as equally or more dangerous relative to combustible cigarettes, even after the true cause of the illness was identified, which may influence decisions about quitting or switching.

“That period really changed how people think about these products,” said lead researcher Tracy Smith, Ph.D., who co-leads the Hollings Cancer Prevention and Control Program. “Even after we learned more about what caused the illness, those perceptions didn’t fully reset.”
