Summary

The CLOUD study is recruiting 500 Canadians aged 12 and older to understand how vaping may harm lungs over time. Researchers will use advanced breathing tests, exercise tests, and imaging to detect early lung damage that standard tests might miss. Participants include both vapers and non-vapers for comparison. This study aims to provide clear information on the health consequences of vaping.
