The proportion of American adults who perceive e-cigarettes to be equally or more harmful than traditional cigarettes has tripled over the last few years, highlighting the need for more accurate public health messaging, according to a study led by tobacco researchers in the School of Public Health at Georgia State University.
"Although the impact of long-term use of e-cigarettes on health is still unknown," the study stated, "the available scientific evidence indicates that e-cigarettes are less harmful than combustible cigarettes, and that smokers switching to e-cigarettes could benefit from a decrease in health risks related to smoking combustible cigarettes."
Researchers looked at data from the Tobacco Products and Risk Perception surveys from 2012 through 2015 to examine changes in how adults in the United States perceived the relative harm and addictiveness of e-cigarettes. The surveys were conducted nationally in 2012, 2014 and 2015 by the Tobacco Center of Regulatory Science (TCORS) at the School of Public Health. Nearly 16,000 adults completed the surveys.
The study results are published in the American Journal of Preventive Medicine in an article titled "Changing Perceptions of Harm of E-Cigarettes among U.S. Adults, 2012-2015." The study's lead author is Dr. Ban Majeed, a postdoctoral research associate with TCORS in the School of Public Health.
According to the survey, 35 percent of adult smokers perceived e-cigarettes to be equally or more harmful than combustible cigarettes in 2015 -- a sizeable increase over the nearly 12 percent who reported that perception in 2012. Also, the proportion of adult smokers who thought e-cigarettes were addictive more than doubled from 25 percent in 2012 to nearly 57 percent in 2015. Similar trends were seen in non-smoking adults.
"The findings underscore the urgent need to convey accurate information to the public, especially adult smokers, about the available scientific evidence of the harm of e-cigarettes compared to combustible cigarettes," the study stated.
"Our public health messages should accurately convey to cigarette smokers that switching completely to e-cigarettes would reduce their risks even if e-cigarettes are addictive and not risk-free," said one of the study's authors, Dr. Michael Eriksen, dean of Georgia State's School of Public Health and a globally recognized expert in tobacco control.
