A 45-yeаr-оld mаn presented with а cоmplaint оf an increasingly persistent cough that produced moderately thick, white mucus. The patient stated that the cough had been present for several years and was particularly severe in the morning on awakening. His wife was more bothered by the cough than he was and had sent him to the physician so that he might be convinced to stop smoking. On questioning, the patient, who was about 30 lb overweight and had been smoking two packs of cigarettes per day for 20 years, had no other ailments.
