About this trial

Vaping is increasingly popular with both adolescent and adult Canadians, but the long-term health impacts remain unknown. We believe that the tools we currently have to detect lung disease in people who vape may be insufficient and propose new ways to find lung injuries that may impact them over the course of their lives. These include exercise testing, new imaging techniques, and new breathing tests that will demonstrate how vaping may harm their lungs. We will use these tools in both adolescent and adult Canadians to give Canadians who vape important information on the consequences of vaping.
