NCT00000568

Brief Summary

In the Lung Health Study I, to determine the effects of Special Care, compared to Usual Care, on rate of decline in pulmonary function in a group of cigarette smokers identified as having mild abnormalities in pulmonary function. In the Lung Health Study III, to determine the long-term effects of smoking cessation and continued smoking, on cardiopulmonary morbidity, mortality, and the rate of decline in the one second forced expiratory volume (FEV1) in men and women with early chronic obstructive lung disease who have been followed prospectively for 12 to 15 years.
