Influence of Smoking Procedures on Combustion Temperature of Cigarettes and the Nicotine Content of Cigarette Smoke

In order to establish fundamental knowledge on the combustion mechanism of tobacco, the effects of smoking procedures on both combustion temperature of cigarettes and the amount of nicotine transferred into cigarette smoke were investigated. The combustion temperatures measured with fine thermocouples specially devised, and an excellent responsive autorecording potentiometer, were 794~827°C, irrespective of smoking procedures. The free burning temperature obtained was 746°C.

When the cigarette was smoked up to a definite length (45 mm) from the lighted end, the amount of nicotine in cigarette smoke increased with increment in puff velocity, showing almost a linear curve.
