A Minnesota study looked to correlate e-cigarette attitudes with experimentation. The study first surveyed young adult participants on e-cigarette attitudes and the completed a follow-up survey to see who actually used e-cigarettes.
Study lead author Kelvin Choi, PhD, said that participants who agreed e-cigarettes can help people quit smoking and those who agreed that e-cigarettes are less harmful than cigarettes were more likely than those who did not agree to subsequently report experimenting with e-cigarettes.Specifically, the follow-up study found that 7.4 per cent of participants who had never used an e-cigarette at baseline reported subsequently using an e-cigarette, with 21.6 per cent among baseline current smokers, 11.9 per cent among baseline former smokers, and 2.9 per cent among baseline nonsmokers reporting use.
Since the survey only looked at ever use, it doesn't tell much of a story, without knowing if that group continued with e-cigarettes. Experimentation and continued use are two different things. Examining if the smokers in the group eventually ditched cigarettes for e-cigarettes was outside of the scope, but would have also provided some interesting insight.
