Respiratory infections are more prevalent and severe among cigarette smokers, particularly heavy smokers, than among nonsmokers, 10. Cigarette smokers appear to develop postoperative pulmo- nary complications more frequently than nonsmokers. CHRONIC OBSTRUCTIVE BRONCHOPULMONARY DISEASE REFERENCES (1) ABpoTT, 0. A., Hopkins, W.
