Please find attached an overview of the “Quash” project from the Lung Health Foundation (LHF). “Quash” is a behaviour change program, featuring an app that aims to help young people (14–30) quit smoking and/or vaping. The program also includes free, online, self-guided training for adults interested in delivering the program to young people. Through the Substance Use and Addictions Program, Health Canada has invested $960.9K over 3 years to fund this project.
