A billion people will die from tobacco-related diseases such as cancer this century unless more are encouraged to quit, a UK expert warns.
In the last century the death toll was about 100m, including 7m in Britain.
Professor Sir Richard Peto told a cancer conference in Birmingham developing countries were likely to be hit hardest.
Many nations are cutting smoking, but rates are increasing in countries such as India and China.
Smoking currently kills about five million adults a year globally.
Each year, about 30m people take up smoking around the world, Professor Peto said.
He added: "If more than 20m of these continue to smoke and half are killed by their habit, then we are going to have more than 10m tobacco-related deaths a year.
