Use of smokeless tobacco among children and adolescents in the United States.

Data collected by National Cancer Institute grantees on the use of smokeless tobacco by youth are reported. Self-reports were collected from over 43,000 students from grades 4 through 11 in 16 locations in the United States and 1 location in Canada. Lifetime and recent use of smokeless tobacco are reported by location, sex, grade level, and ethnic group. Use of smokeless tobacco increased with grade level. Typically, 40 to 60% of males had tried smokeless tobacco, and in most locations, 10 to 20% of older male youths reported recent use. With the exception of Native Americans, rates of use among females were lower than those among males. Use was highest among Native Americans and lowest among blacks and Asians. Smokeless tobacco use by Hispanics was comparable to that by whites. Collectively, the data indicate that large numbers of male youths in many areas of the United States are using smokeless tobacco. In light of recent research on the health consequences of using smokeless tobacco, the health of these youth may be endangered.
