28 chemicals in chewing tobacco are believed to cause cancer. Nitrosamines are created in tobacco plants as they grow, cure, ferment, and age. Each tobacco plant contains different levels depending on variance in these factors. Researchers have found that nitrosamines are directly related to the risk of developing many types of cancer, as is a person's overall heath and genetic makeup.
