—If cigarette smoking is as lethal as authorities continue to say it is,1 why have the experimental outcomes of randomized intervention trials2-5 failed to date to indicate (by generating greater mortality rate reductions among baseline-defined smokers than among baseline-defined nonsmokers) that successful smoking cessation guidance prolongs survival? How can the outstanding longevity of Japanese men be reconciled with a smoking prevalence among them that is higher than for most other countries? Why is the approximate 4.6:1 ratio of male-to-female cigarette smoking prevalence for Japan, vs only about 1.3:1 for the United States, not reflected in a wider gap between men's and women's life expectancy for the Japanese than for the Americans?
