If there had been no snus in Sweden: the impact of snus on mortality attributable to smoking.

In Sweden, there has been a massive transition from cigarette smoking to snus, the Swedish kind of low-toxicity oral tobacco. This product poses very little health risk compared to cigarettes, as illustrated by the fact that males in Sweden have Europe's lowest level of mortality attributable to smoking. The current investigation estimates how high the smoking-attributable mortality in Sweden would have been if there had been no snus in Sweden. It is made up by comparisons between observed Swedish data and two scenarios without snus: a group of comparable countries, and, a hypothetical Sweden with no snus use. Both comparisons suggest that around 3000 lives per year have been saved by the use of snus in Sweden.
