Relationship between puff intensity and smoke yields from a series of different smoking regimes

Imperial Tobacco Group data from two commercially available cigarettes, sold in the early 1980s and having 0 and 28% filter ventilation was presented this year at an ISO TC126 Working Group 10 meeting. The products had been smoked at different puffing frequencies and puff volumes. By using the parameter of puff intensity (expressed in mL/min) as the product of puff volume and frequency it was shown that NFDPM, nicotine and CO yields could be predicted for any smoking regime. Some of the WG10 members asked whether similar results would be obtained with currently available cigarettes. Data is presented on such products with both ventilated and non-ventilated commercial cigarettes from Morocco and Arabic countries. Cigarettes were smoked by 16 machine smoking regimes (Filtrona, SM450) covering 17.5 mL to 70 mL per puff, frequencies from 1 to 3 puffs per minute and a constant 2 second puff duration. Data is put into context with currently used or proposed smoking regimes and with human smoking data obtained on these two products.
