Carcinogens: At least 28 chemicals (carcinogens) in smokeless tobacco can cause cancer. The most harmful chemicals are tobacco-specific nitrosamines, which are formed during the growing, curing, fermenting, and aging of tobacco. The level of nitrosamines varies by product and scientists have found that the nitrosamine level is directly related to the risk of cancer.
