Research on e-cigarette use in children is only just
emerging, yet studies in several countries are showing
their rapid penetration into adolescent markets. In the
USA, studies show that lifetime e-cigarette use in grades
6-12 school students (~age 11-18) more than doubled
from 3.3% in 2011 to 6.8% in 2012 [1]. Whilst most
e-cigarette users in the 2012 survey were current smokers,
9.3% had never smoked a conventional cigarette. In
France, a 2012 study of Parisian school students aged 12-
19 years found that 8.1% had tried e-cigarettes, with
prevalence ranging from 4.4% of non-smokers up to
33.4% of regular smokers [8]. In Korea, prevalence of ever
using e-cigarettes in 13-18 year olds was found to have increased
almost 20-fold between 2008 and 2011, from 0.5%
to 9.4%, with 1.4% of e-cigarette users in 2011 having
never smoked cigarettes
