Protect your health; don’t start. If you do use them, quit.Addiction to Smokeless TobaccoSmokeless tobacco contains nicotine, which is highly addictive.1,2
Because young people who use smokeless tobacco can become addicted to nicotine, they may be more likely to also become cigarette smokers.5Smokeless Tobacco and CancerMany smokeless tobacco products contain cancer-causing chemicals.1,6The most harmful chemicals are tobacco-specific nitrosamines, which form during the growing, curing, fermenting, and aging of tobacco. The amount of these chemicals varies by product.1
The higher the levels of these chemicals, the greater the risk for cancer.2
Other chemicals found in tobacco can also cause cancer. These include:6A radioactive element (polonium-210) found in tobacco fertilizer
Chemicals formed when tobacco is cured with heat (polynuclear aromatic hydrocarbons—also known as polycyclic aromatic hydrocarbons)
Harmful metals (arsenic, beryllium, cadmium, chromium, cobalt, lead, nickel, mercury)Smokeless tobacco causes cancer of the mouth, esophagus, and pancreas.1Smokeless Tobacco and Oral DiseaseSmokeless tobacco can cause white or gray patches inside the mouth (leukoplakia) that can lead to cancer.1
Smokeless tobacco can cause gum disease, tooth decay, and tooth loss.1,3Reproductive and Developmental RisksUsing smokeless tobacco during pregnancy can increase the risk for early delivery and stillbirth.2
Nicotine in smokeless tobacco products that are used during pregnancy can affect how a baby’s brain develops before birth.2,7Other RisksUsing smokeless tobacco increases the risk for death from heart disease and stroke.1,3
Smokeless tobacco can cause nicotine poisoning in children.4
