Prevention projects investigate the prevalence and predictors of tobacco use and other health risk behaviours among young people during the transition from adolescence to adulthood, the impact of social exposure on youth perspectives about smoking and smoking behavior, and the influence of social networks on the smoking behavior of youth.

A study of electronic cigarettes includes an examination of the role of e-cigarettes as a “gateway” to uptake of traditional cigarettes. A project is also underway to examine gaps in knowledge about effective interventions to reduce the uptake and use of tobacco in Aboriginal communities in Ontario. Additional studies reach across the three pillars of tobacco control to model the impact of policy and program measures including those related to prevention.
