NCT ID NCT02797275
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at how long-term exposure to secondhand tobacco smoke changes the lungs of never-smoking flight attendants who worked on planes before smoking was banned. Researchers want to see if a bronchodilator, a medicine that opens airways, can help with breathing problems found in this group. The study involves 107 participants and uses exercise tests to measure lung function.
