Answer 2

Answer:

Cancer , Precancerous mouth lesions , Heart disease , Dental disease , Pregnancy risk , Poison risk for children

Explanation:

Cancer. The use of chewing tobacco and other smokeless tobacco products increases the risk of oral cancers — cancer of the mouth, throat, cheek, gums, lips or tongue. There's also an increased risk of cancers of the pancreas and esophagus, the long tube that runs from your throat to your stomach.

Precancerous mouth lesions. Smokeless tobacco increases your risk of developing small white patches called leukoplakia (loo-koh-PLAY-key-uh) inside your mouth. These mouth lesions are precancerous — meaning that the lesions could one day become cancerous.

Heart disease. Some forms of smokeless tobacco increase your heart rate and blood pressure. Evidence suggests that long-term use of smokeless tobacco increases your risk of dying of heart disease and stroke.

Dental disease. The sugar and irritants in smokeless tobacco products can cause cavities, abrasion of teeth, teeth staining, bad breath, gum disease, receding gums, bone loss around roots and tooth loss.

Pregnancy risk. Studies have shown that the use of smokeless tobacco, including Swedish snus, may increase the risk of stillbirths, low birth weight and heart rate variability in infants.

Poison risk for children. The candy-like appearance or flavors of smokeless tobacco products make them attractive to children. Ingestion of these products can cause nicotine poisoning. Effects of nicotine poisoning in children may include nausea, vomiting, weakness, convulsions, unresponsiveness, impaired breathing and death.
