Effects of Varied Smoking Machine Parameters on Deliveries of Total Particulate Matter and Selected Smoke Constituents from an Ultra Low-Tar Cigarette

Abstract

A typical ultra low-tar cigarette was mechanically smoked under varying conditions designed to simulate potential changes in human smoking behavior. Determination of the yields of total particulate matter and analyses of individual smoke components, including nicotine, phenolics, acids, and the humectant, glycerol, demonstrated significant changes in smoke composition as related to intensity and frequency of inhalation. Physical obstruction of tipping paper ventilation, by negating the effects of air dilution of smoke, resulted in increased smoke deliveries similar to those observed when puffing volume and frequency were increased.
