Abstract: Numerous scientific studies and epidemiological surveys have shown that smoking can lead to various diseases, especially lung diseases. Smoking is both harmful to smokers’ health, also seriously endangering others’ health through secondhand smoke. Loss of the economic costs of tobacco use causes far more than the benefits of tobacco. WHO advocated for the members to control the dangers of tobacco extensively, and promulgated “WHO FCTC” and “MPOWER”. China’s implementation of tobacco control convention would be long and arduous, but we will eventually move towards smoke-free China as long as the whole society pay the unremitting efforts.
