Acute effects of smoking tobacco and a tobacco substitute on lung function in man.
The acute effects on airway function of smoking one cigarette of a tobacco substitute 'New Smoking Material' (NSM), one cigarette of conventional tobacco, and one cigarette containing 70% tobacco and 30% NSM, were studied in 6 healthy nonsmokers and 6 healthy smokers. None of the cigarettes produced any change in three tests of small-airway function (flow-volume curves, closing volume, frequency dependence of compliance). However, smoking either one conventional tobacco cigarette or the 30% NSM/70% tobacco cigarette produced an acute fall in specific airways conductance, of similar degree with both cigarettes, whereas the 100% NSM cigarette produced no such change.
