Strengthening tobacco control must remain a global health priority

Abstract

In the almost 60 years since the publication of the landmark US Surgeon General's report on the health consequences of smoking in 1964,1 even stronger evidence on the health risks of smoking has accrued from a wealth of research.2 However, there is a dominance of studies from high-income countries and hence uncertainty on whether risk estimates are generalisable to countries at different economic levels. In The Lancet Global Health, Thirunavukkarasu Sathish and colleagues3 have, for the first time, to our knowledge, studied systematically whether risks associated with smoking differ across country income categories.
