It is common knowledge that pipe and cigar smoking does not affect lung function. This was tested on 3,528 subjects, 9% of whom were pipe smokers, 11% cigar smokers and 52% cigarette smokers (Ann Intern Med 2010; 152: 201–10). Pipe and cigar smokers had elevated urine cotinine levels, establishing that contrary to popular belief many such individuals do inhale smoke. Pipe smoking resulted in a reduced forced expiratory volume while both pipe and cigar smokers were more likely to have some degree of respiratory obstruction. Clearly pipe and cigar smoking has an adverse effect on lung function. Common knowledge is not always accurate knowledge.
