Group Intervention Description On the Road to Quitting - Self Help On the Road to Quitting - Self Help The control group will receive an evidence-based self-help guide known as "On the Road to Quitting"(45) that has been developed by Health Canada for young adult smokers. Participants will be able to both view the self-help guide via the internet and will receive a printed version of the guide. Crush the Crave Application Crush the Crave Application Crush the Crave (CTC) intervention group will receive a quit smoking smartphone intervention via the internet that is based on scientific findings related to tobacco use among young adults. It is a multi-component intervention informed by evidence on quitting smoking. The app was developed with the input of key experts in the field of smoking cessation, was assessed against Fiore's practice guidelines for treating tobacco use and dependence, and was tested with eight focus groups of male and female young adult smokers (n=57) on functionality, look and feel and usability, as well as being piloted by over 300 smokers.
