There are many smokers in the world. In 2007, WHO said that 1.1 billion people are smoking in the world, accounting for 1/3 of the world's population over the fifteen years. In particular, there are many smokers in developing countries. That number is 800 million. 700 million of them are men. 200 million men and 100 million women are smoking cigarettes in developed countries. In Japan, 20 million men and 7 million women are smoking. I want cigarette to disappear from the world. It is because smoking is not good for health.
