Use of smokeless tobacco by age, race, and gender in ten standard metropolitan statistical areas of the southeast United States.

Most surveys of smokeless tobacco use have been limited to young people, and in the few studies of adults, researchers have not considered age, race, and gender simultaneously, although broad age groups have been used. Data on smokeless tobacco use by race and gender for 5-year age groups up to age 70 and older were compiled from 21,203 households in 10 Standard Metropolitan Statistical Areas of the southeastern United States.
