Avoid Smoking With COPD
In chronic obstructive pulmonary disease (COPD), two lung diseases make breathing more difficult. Chronic bronchitis inflames and narrows airways (bronchi) and makes phlegm, while emphysema destroys parts of the lungs. If you smoke, quitting smoking can prevent more damage to your lungs. Even secondhand smoke can worsen COPD, so try avoiding it. For help with quitting smoking or avoiding secondhand smoke, talk to your doctor.
