About half of cigarette smokers and young adult non-smokers think that nicotine-based electronic cigarettes have the same amount or even more harmful chemicals than regular tobacco-based cigarettes, according to a Rutgers study. The study, published in Addiction, measured perceived levels of harmful chemicals in e-cigarettes compared with cigarettes using national samples of more than 1,000 adults ages 18 and older who smoke cigarettes and 1,000-plus adults ages 18 to 29 who are nonsmokers. The study also measured associations with e-cigarette/cigarette relative harm perceptions, e-cigarette use and interest. About 20 percent of all participants believed e-cigarettes contain fewer harmful chemicals than cigarettes, while about 30 percent responded that they did not know how the levels compared.

“Our results were interesting to see given that previous review reports suggest e-cigarettes expose users to fewer types and lower levels of harmful and potentially harmful chemicals than cigarettes,” said Olivia Wackowski of Rutgers Center for Tobacco Studies, an associate professor at the Rutgers School of Public Health and lead researcher of the study. “It was also interesting to find that only about half of adult smokers who thought e-cigarettes have fewer harmful chemicals also thought e-cigarettes are less harmful to health.” To read the full story.
