In "tobacco-related disease mortality among men who switched from cigarettes to spit tobacco" Tob Control 2007; 16: 22-28, Henley, et al compared mortality rates for smokers who switched to spit tobacco to the rates for those who quit all forms of tobacco. This is useful information. However, the fact that the number of smokers in the US has remained relatively unchanged for the past 20 years tells us that there are tens of millions of smokers who cannot or will not overcome their dependence on nicotine. Thus, it is vital for tobacco policy makers to establish viable harm-reduction plans. Was there mortality data collected on the group who continued smoking? If so, it would be very useful for the authors to publish a follow-up article that compares the mortality rates for switchers to the rates of those who continued smoking.
NOTE: The research was conducted under the auspices of the American Cancer Society. I'll bet you they DO have the data, and I will bet you that the mortality rates for the continuing smokers was vastly higher that for the switchers. Any takers?
