Smokeless tobacco is associated with many health problems. Using smokeless tobacco:
- Can lead to nicotine addiction.
- 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).
- Is associated with diseases of the mouth.
- Can increase risks for early delivery and stillbirth when used during pregnancy.
- Can cause nicotine poisoning in children.
- May increase the risk for death from heart disease and stroke.
- Many smokeless tobacco products contain cancer-causing chemicals.
– 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.
– The higher the levels of these chemicals, the greater the risk for cancer.
– Other chemicals found in tobacco can also cause cancer. These include:
- 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 and Oral Disease
- Smokeless tobacco can cause white or gray patches inside the mouth (leukoplakia) that can lead to cancer.
- Smokeless tobacco can cause gum disease, tooth decay, and tooth loss.
