To the Editor.—Dr Lam and colleagues1 and Dr Chen and colleagues2
report striking data that quantify the impact of tobacco use on smoking-related

in research methods that is common to virtually all scientific reports of
smoking-related disease statistics: they use an inaccurate and potentially
misleading categorization of smoking status.
