Theoretical and experimentally quantifiable determinants of tobacco smoking behavior for the development of successful smoking cessation strategies.

Death rates from a number of diseases linked epidemiologically to tobacco use continue to rise despite major reductions in per capita tobacco consumption, despite reductions in the total number of smokers, and despite very significant reductions in "tar", in other tumorigens and in essentially all classes of potential toxins in smoke delivered to the consumer. One concern is that smokers consume low delivery cigarettes differently and in a potentially more hazardous way than higher delivery cigarettes. The effect of nicotine reduction in cigarettes on human smoking behavior was studied in 102 human subjects by quantifiable determinants of tobacco-smoking behavior. This study indicates that reduction in nicotine delivery results in some accommodation in smoking behavior to titrate nicotine needs. In addition, smokers appear to adjust their smoking behavior as a function of taste preference, and this adjustment is as strong as the accommodation for nicotine. The theoretical application of these observations to the development of successful smoking cessation strategies is reviewed.
