Does Chronic Obstructive Pulmonary Disease (COPD) result from heavy smoking?
COPD is a slow, progressive disease of the airways characterized by shortness of breath, a chronic cough and excess mucus when you cough. If you are a smoker or ex-smoker and have been diagnosed with COPD, you may qualify for a clinical research study of an investigational medication for the treatment of COPD.
