Results: About 36.9% of 15-year-olds reported lifetime smoking of conventional cigarettes, and 16.6% lifetime use
of e-cigarettes, mostly experimenting (0.5% reported current e-cigarette use). Six in 7 ever e-cigarette smokers
had smoked conventional cigarettes. Peers who smoke and lifetime cannabis use were significant correlates of
both lifetime conventional cigarette and e-cigarette smoking, but more strongly for smoking conventional cigarettes.
Alcohol use and low parental monitoring correlated with tobacco smoking but not e-cigarette use. Girls
were more likely than boys to report lifetime use of tobacco, but, among lifetime smokers, boys had almost
seven times the odds of girls of e-cigarette use. In lifetime smokers, low life satisfaction in females and current
smoking of conventional tobacco were independently associated with the experimentation with e-cigarettes.
