Electronic cigarettes use among young people - risks factors for its initiation and escalation, impact on mental health, and its effect on smoking cessation
Electronic cigarettes and personal vaporisors have been gaining popularity in many developed countries such as the US, Canada and the UK. It has been promoted as a cessation device for smokers, thus it holds the potential to reduce smoking related burden on the society. However, it also raises concerns that its uptake among young people may renormalise cigarette smoking. This projects will evaluate the overall evidences of its benefit and harms on public health.

Understanding initiation, escalation and remission of substance use from adolescence to mid-adulthood: A life course approach
It is well known that adolescence is a period of experiementation and many adolescents may experience with illicit substance during this period. While many of them do not progress into problematic use (e.g. abuse and dependence), some have escalated their use during their 20s and maintained their habits into 30s and 40s. This project will take a life course approach to understand risk factors for substance initiation and escalation, and factors that are linked to natural remission of substance us in mid-adulthood.
-
