Sweden VS US


Swedish cigarettes would seem to cause lung cancer in the year of purchase.

US cigarettes would seem to cause lung cancer ~20 years after year of purchase.
The point here is that the lung cancer epidemic in Sweden started at the same time as the US epidemic despite the fact that Sweden was ~20 years late in taking up smoking cigarettes compared to the US. As far as can be worked out, all cancer mortality in many countries is stable up until ~1950, unlike cigarette consumption, which would imply that the rise in cancers post WWII is independent of cigarette consumpton.
