An article published on October 10, 2015, in The Lancet medical journal entitled "Contrasting male and female trends in tobacco-attributed mortality in China: evidence from successive nationwide prospective cohort studies" describes the results of two long-term studies on cigarette smoking in China.

Essentially, the studies show that Chinese men smoke more than a third of the world's cigarettes, two-thirds of Chinese men smoke cigarettes, and Chinese women smoke much less. Regarding mortality, the conclusions of the studies are:

Smoking will cause about 20% of all adult male deaths in China during the 2010s.

...the annual number of deaths in China that are caused by tobacco will rise from about 1 million in 2010 to 2 million in 2030 and 3 million in 2050, unless there is widespread cessation.
