The photograph of an Asian person puffing on a cigarette and the map of the top cigarette-consuming countries, both shown in J. M. Samet and H. L. Wipfli's Opinion article (Nature 463, 1020–1021; 2010), make China look like a smokers' paradise.

Its large population may make China the top consumer of cigarettes in the world. But, as is shown more clearly in the online version of the Tobacco Atlas map (http://go.nature.com/jQNEWc), the populations of many other countries, especially in Europe, smoke more per person — the heaviest smokers being in Greece and Ukraine.
