[E-Cigarettes on Everyone's Lips - Current Representative Data on Use Among Adolescents and Adults].

International data suggest an increase in e-cigarette use. However, there are still significant deficits in the reporting of its current prevalence. The present study reports representative data on e-cigarette use that make it possible to differentiate users both by the nicotine content of the e-cigarette liquids being used and by their smoking status.  The underlying data are taken from the National Cancer Aid Monitoring (NCAM). In its first wave, 3000 persons aged between 14 and 45 were interviewed by telephone. Point estimates, confidence intervals and determinants of use will be presented.  Overall, 20 % of respondents had used an e-cigarette before, of which 80 % used liquids containing nicotine. Men, younger persons, persons with a migrant background and persons with a lower education level were more likely to have used an e-cigarette before than their respective reference groups. Half of all ever users of e-cigarettes also smoked tobacco cigarettes, while roughly one third had never used tobacco products before.  For the first time, a representative study was conducted combining questions on the use of e-cigarettes with questions on smoking tobacco cigarettes and the nicotine content of the liquids being used. Target groups for future prevention measures are adolescents, as they had the highest prevalence of e-cigarette use, as well as non-smokers, since one third of e-cigarette users had never used a tobacco product before. Both groups also seem to be relevant target groups for which the introduction to e-cigarettes should be prevented.
