The World Health Organization (www.who.org) is the part of the United Nations that oversees health issues in the world. The WHO leads numerous studies on tobacco use around the world. In its study on Gender and Tobacco, the organization learned that tobacco use among women is increasing. For example, recent research shows that just as many young girls smoke as young boys. The report is filled with information about percentages of women who smoke, percentages of men who smoke, and the percentage of smokers who start smoking by age 10.
