Tobacco smoke: We all slowly lose lung function as we grow older, typically most non-smokers will die with greater than 80% of their lung function. Smokers lose lung function at a faster rate. If they stop, the rate of decline typically slows to the same rate as non-smokers. Most people do not experience activity limitations until they have less than 80% capacity.

I agree that cigarette smoke exposure is a potent irritant to the airway and causes multiple short and long term pulmonary function abnormalities. The exposure to the deleterious chemical contained in cigarettes may alter the structure of the lung and is one of the primary risk factors for COPD/Emphysema.
