Abstract
During the last months there have been extensive discussions, particularly in the United States, whether and to what extent data obtained by machine smoking using standardized methods (e.g. ISO, FTC, Coresta) permit conclusions about the actual uptake of smoke constituents (nicotine, condensate, etc.) by a smoker. This topic was a major focus of interest at the meeting of the Coresta Smoke and Technology Group in Vienna from 10th to 14th September 1995. A total of five studies were presented, four of which compared smoke yields obtained by standard machine smoking with actual yields obtained by human smoking. The fifth study investigated the effect of alternative puffing regimens and filter vent blocking on “tar” and nicotine yields of cigarettes. This paper summarizes the essential findings of the five studies.
