Cigarette smoking in the People’s Republic of China (PRC) is a highly gendered practice. The vast majority of China’s three hundred million plus smokers are men: in 2016, about 48 percent of men over age 15 were current smokers, but less than 2 percent of women smoked. The stark difference in this pattern of men and women’s smoking behavior is often attributed to lingering cultural taboos against female smoking assumed to have been in place for centuries. In fact, the virtual exclusivity of male smoking in China is of relatively recent vintage, dating only from the mid-1900s. From the 17th to the 19th centuries, smoking was socially acceptable for Chinese women. Granted, there were gendered and class differences in the location of tobacco consumption. Chinese men could smoke in public, but well-mannered women smoked privately out of view. After cigarettes were introduced into China at the end of the 19th century, some women, especially those living in coastal cities, took to smoking them rather than pipe tobacco. In the opening decades of the 20th century, the number of women who smoked cigarettes increased, but this trend was reversed in the 1930s and 1940s. After the establishment of the PRC in 1949, the number of women who smoked diminished even further such that by the 1980s, only a small percentage of women consumed tobacco products of any kind. Many social, economic, and cultural factors contributed to the gendered pattern of smoking that emerged in China over the course of the 20th century. An essential aspect of this history was the transformation in social norms that made cigarette smoking less rather than more respectable for women as time went on. At the beginning of the century, many women were already accustomed to smoking pipe tobacco. Some women, including those who identified as forward-looking “New Women,” preferred cigarettes. However, by mid-century cigarettes came to be widely associated with a stigmatized type of New Woman known as the “Modern Girl.” Portrayed in popular culture and political rhetoric alike as extravagant and sexually promiscuous, the Modern Girl’s pursuit of luxury came to symbolize bourgeois decadence and insufficient national loyalty. These associations came forward into the PRC period and as a result, most women born after 1949 elected not to smoke at all. Major differences in male and female smoking prevalence rates persist because female smoking remains objectionable to many Chinese citizens in the 21st century.
