1 Smokeless tobacco products are a major source of cancer-causing nitrosamines and a known cause of human cancer. 2  They increase the risk of developing cancer of the mouth and throat, esophagus (swallowing tube), and pancreas. Tobacco use accounts for at least 30% of all cancer deaths, causing 87% of lung cancer deaths in men, and 70% of lung cancer deaths in women. ( 2 Source: Cancer Facts & Figures 2014).
Chewing tobacco and snuff contain 28 carcinogens (cancer causing agents). The most harmful carcinogens in smokeless tobacco are the tobacco specific nitrosamines (TSNA's). Snuff dippers consume on average more than 10 times the amount of cancer causing substances (nitrosamines) than cigarette smokers.Smokeless tobacco is a known carcinogen (U.S. Dept. of Health & Human Services, Report on Carcinogens, December 2002). *Approximately 31,000 new cases of oral cancer will be diagnosed in the U.S. in 2006; nearly two-thirds are male. Estimated deaths from oral cancer in 2004 are at 4,830 men and 2,400 women.
