Smokeless tobacco is associated with many health problems. Using smokeless tobacco:

  • Can lead to nicotine addiction1,2
  • Causes cancer of the mouth, esophagus (the passage that connects the throat to the stomach), and pancreas (a gland that helps with digestion and maintaining proper blood sugar levels)1,2
  • Is associated with diseases of the mouth1,3
  • Can increase risks for early delivery and stillbirth when used during pregnancy2
  • Can cause nicotine poisoning in children4
  • May increase the risk for death from heart disease and stroke1,3

Using smokeless products can cause serious health problems.
Protect your health; don’t start. If you do use them, quit.

Addiction to Smokeless Tobacco

  • Smokeless 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.5

Smokeless Tobacco and Cancer

  • Many smokeless tobacco products contain cancer-causing chemicals.1,6
    • The 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:6
      • A 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.1

Smokeless Tobacco and Oral Disease

  • Smokeless 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.1,3

Reproductive and Developmental Risks

  • Using 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.2,7

Other Risks

  • Using smokeless tobacco increases the risk for death from heart disease and stroke.1,3
  • Smokeless tobacco can cause nicotine poisoning in children.4
  • Additional research is needed to examine long-term effects of newer smokeless tobacco products, such as dissolvables and U.S. snus.
