Risky business: a longitudinal study examining cigarette smoking initiation among susceptible and non-susceptible e-cigarette users in Canada.

ABSTRACT:

Objectives

Given that many adolescent e-cigarette users are never-smokers, the possibility that e-cigarettes may act as a gateway to future cigarette smoking has been discussed in various studies. Longitudinal data are needed to explore the pathway between e-cigarette and cigarette use, particularly among different risk groups including susceptible and non-susceptible never-smokers. The objective of this study was to examine whether baseline use of e-cigarettes among a sample of never-smoking youth predicted cigarette smoking initiation over a 2-year period.

Design

Longitudinal cohort study.

Setting

89 high schools across Ontario and Alberta, Canada.

Participants

A sample of grade 9-11 never-smoking students at baseline (n=9501) who participated in the COMPASS
