It's not surprising that the most serious effect of using smokeless tobacco—also known as spit tobacco, chewing tobacco, or dip—is an increased risk of cancer of the mouth and pharynx. Smokeless tobacco is absorbed quickly and directly through the inside of the mouth, making it very dangerous . . . and potentially deadly. Research has shown more than half of smokeless tobacco users have noncancerous or precancerous lesions in their mouth, with their chance of getting oral cancer being 400 percent greater than for nonusers. Oral cancer kills 50 percent of its victims within five years of diagnosis.
The Tips on Spit brochure spreads the word that smokeless tobacco is not harmless tobacco. The brochure outlines the dangers of smokeless tobacco and provides tips on how to stop using.
