Objectives: Declines in cigarette smoking have been accompanied by increases in alternative tobacco product (ATP) use, particularly among youth. This study examines smoking susceptibility and ATP use in a national sample of Canadian youth. Methods: Data from grades 9-12 students who participated in the 2012/2013 Youth Smoking Survey, a nationally generalisable sample of Canadian students (n=27 404) were used to examine cigarette smoking susceptibility among never smokers (n=17 396). Logistic regression models were used to examine differences in smoking susceptibility by use of flavoured and all ATPs and by sociodemographic and lifestyle characteristics. Results: Overall, 30% of Canadian grades 9-12 never smokers were susceptible to cigarette smoking. Compared to never users, those who had ever tried ATPs (OR=1.96, 95% CI 1.59 to 2.42) and those who had ever tried flavoured ATPs (OR=2.20, 95% CI 1.63 to 2.96) had significantly higher odds of being susceptible to cigarette smoking. Conclusions: ATP use is associated with smoking susceptibility among youth never smokers. Findings from this study, along with existing evidence, can be used by policymakers to improve regulation around youth access to ATPs (particularly flavoured varieties).
