We assessed whether e-cigarette use is associated with (1) intention to smoke cigarettes among never-smoking youths and youth experiementers, and (2) intention to quit smoking among current youth smokers. We categorized participants from the 2012 National Youth Tobacco Survey data (n=20,193) as never-smoking youth (n=16,238), youth experimenters (n=3,248), and current youth smokers (n=707). We match groups on the basis of propensity score comprising covariates predicting e-cigarette use.
E-cigarette users who has never smoked cigarettes (adjusted odds ratio [AOR] = 3.62; 95% confidence interval [CI] = 2.04, 6.45) and who had experimented with smoking (AOR = 1.99; 95% CI=1.50, 2.64) had elevated intention to smoke cigarettes compared with their counterparts who had never used e-cigarettes. We did not find any significate association between e-cigarette use and intention to quit smoking among current youth smokers (P=.33). E-cigarette use among US youths is associated with intention to smoke but not with intention to quit smoking.
