snuff tobacco
(… tuh-BA-koh)
A type of smokeless tobacco that is made of finely ground or shredded tobacco leaves. It may have different scents and flavors and may be moist or dry. Moist snuff tobacco is placed in the mouth, usually between the cheek and gum or behind the upper or lower lip. Dry snuff tobacco is inhaled through the nose. Snuff tobacco contains nicotine and many harmful, cancer-causing chemicals. Using it can lead to nicotine addiction and can cause cancers of the mouth, esophagus, and pancreas. Snuff tobacco use may also cause gum disease, heart disease, stroke, and other health problems. Using snuff tobacco is also called “dipping.”
