BEIJING (AP) — Research published in the medical journal The Lancet says one in three of all the young men in China are likely to die from tobacco, but that the number can fall if the men quit smoking. The studies, conducted by researchers from Oxford University, the Chinese Academy of Medical Sciences and the Chinese Center for Disease Control, show that two-thirds of the young men in China start to smoke, mostly before age 20, and that half of those would eventually be killed by tobacco unless they stop permanently. The research published in The Lancet shows that the number of young men smoking in China has increased, and the percentage of all male deaths in China that can be attributed to smoking is rising, while the younger generations of Chinese women have become less likely to smoke compared to those born in the 1930s.
