As many as 1 in 6 working women of child-bearing age in the U.S. are cigarette smokers and numbers vary widely across industries and occupations according to a National Institute for Occupational Safety and Health (NIOSH) study published this month in Nicotine & Tobacco Research.

We estimated that about 1 in 10 nonsmoking, working women of reproductive age in the United States are exposed to secondhand smoke at work. Women working in the accommodations and food services industry (women working in hotels, restaurants, or bars) were more than twice as likely as women employed in other industries to be exposed to secondhand smoke at work.
