This study is creating a research registry and biosample repository for people with emphysema, chronic obstructive pulmonary disease (COPD), or chronic bronchitis, and a comparison group without lung diseases. The goal is to gather information to better understand emphysema and develop new treatments. There are no specific interventions being tested. You can join if you are 21 or older and have a diagnosis of COPD based on clinical history, lung function tests, or X-rays. The study is currently unclear about its status, but it plans to enroll up to 3000 participants.
