This Canadian research study is investigating the role of mucus buildup in three common lung diseases: asthma, COPD, and chronic cough. Researchers want to understand how mucus contributes to symptoms and how it changes over time, using advanced imaging and breathing tests. By comparing people with these conditions to healthy volunteers, the study aims to find better ways to identify and treat mucus-related problems.
Mucus plays a major role in lung disease symptoms, but doctors have had difficulty measuring and assessing it. This study exists to use modern imaging technology to better understand mucus buildup and potentially identify new ways to treat it more effectively.

Participants will visit the research center twice—at the start and again two years later. During each visit, you'll complete breathing tests, provide a sputum (mucus) sample, have a CT scan of your chest, answer quality-of-life questions, and possibly wear a device to monitor coughing. The study involves standard medical tests and imaging, with no experimental medications.
