Tobacco (smoked, chewing)
Tobacco use is the leading cause of preventable illness and death in the United States. If nobody smoked, one of every three cancer deaths in the United States would not happen. It causes many different cancers as well as chronic lung diseases such as emphysema and bronchitis, heart disease, pregnancy-related problems, and many other serious health problems. Smoking causes many other types of cancer, including cancers of the throat, mouth, nasal cavity, esophagus, stomach, pancreas, kidney, bladder, and cervix, as well as acute myeloid leukemia. Babies who breathe secondhand smoke are sick more often with bronchitis, pneumonia, and ear infections.

Smokeless/Chewing Tobacco contains 28 cancer-causing agents (carcinogens). It is a known cause of cancer; it causes oral and pancreatic cancer. It is also strongly associated with leukoplakia—a precancerous lesion of the soft tissue in the mouth that consists of a white patch or plaque that cannot be scraped off.
It is associated with recession of the gums, gum disease, and tooth decay.
Smokeless tobacco use during pregnancy increases the risks for preeclampsia (i.e., a condition that may include high blood pressure, fluid retention, and swelling), premature birth, and low birth weight. Smokeless tobacco use by men causes reduced sperm count and abnormal sperm cells.
Snuff is finely cut or ground tobacco that may be flavored. It’s available in dry or moist forms and is packaged in tins or teabag-like pouches. A pinch of snuff is placed along the gumline, either behind the lip or between the gum and cheek. Using snuff is also called dipping. Dry snuff also can be sniffed into the nose. Snuff is not only highly addictive, but also harmful to your health. You might think that using snuff isn’t as dangerous as smoking because you’re not inhaling smoke into your lungs. However, snuff can still negatively impact your body. Like other forms of tobacco, snuff contains cancer-causing chemicals. It can raise your risk of several types of cancer, including nose and sinus cancers, oral cancers, esophageal cancer, pancreatic cancer.
