Mouth, Gums and Throat â Tobacco use can cause bad breath, tooth decay, cavities, stained teeth and gum disease. There is also a risk of getting cancer in the mouth, gums and throat, especially among smokeless tobacco users (who chew or suck on tobacco) and cigar smokers (who often hold the smoke in their mouth).
Smokeless tobacco, also called spit tobacco, includes chewing tobacco (dip and chew), tobacco powder (snuff), as well as flavored tobacco lozenges. These products also contain nicotine. Smokeless tobacco products allow tobacco to be absorbed by the digestive system or through mucous membranes. Smokeless tobacco contains at least 28 cancer-causing substances, and is not a safe substitute for smoking cigarettes or cigars. According to the National Institutes of Health, chewing on an average-size piece of chewing tobacco for 30 minutes can deliver as much nicotine as smoking three cigarettes.
