Specifically, the follow - up study found that 7.4 % of participants who had never used an e-cigarette at baseline reported subsequently using an e-cigarette, with 21.6 % among baseline current smokers, 11.9 % among baseline former smokers, and 2.9 % among
baseline nonsmokers reporting use.
«The study showed that 2.9 % of
baseline nonsmokers in this U.S. regional sample of young adults reported ever using e-cigarettes at follow - up, suggesting an interest in e-cigarettes among nonsmoking young adults,» explains Dr. Choi.
