Abstract

To evaluate risk factors and to approach methods of reduction of the carcinogenic potential of cigarette smoke, the transfer rate of N-nitrosonornicotine in a popular U.S. blended cigarette into mainstream smoke was quantitatively determined. The mean transfer rate was 11.3%; thus ≈46% of the tobacco-specific carcinogen In the smoke came from the tobacco, and the remainder was synthesized during smoking.
