Smoking and COPD

Chronic obstructive pulmonary disease - smoking; COPD - secondhand smoke

Smoking is the leading cause of chronic obstructive pulmonary disease (COPD). Smoking is also a trigger for COPD flare-ups. Smoking damages the air sacs, airways, and the lining of your lungs. Injured lungs have trouble moving enough air in and out, so it's hard to breathe.
