Smokeless tobacco effects: chewing and snuff
The two main types of smokeless tobacco in the United States are chewing tobacco and snuff. Chewing tobacco comes in the form of loose leaf, plug, or twist. Snuff is finely ground tobacco that can be dry, moist, or in sachets (tea bag-like pouches).
Although some forms of snuff can be used by sniffing or inhaling into the nose, most smokeless tobacco users place the product in their cheek or between their gum and cheek.3 Users then suck on the tobacco and spit out the tobacco juices, which is why smokeless tobacco is often referred to as spit or spitting tobacco. Smokeless tobacco is a significant health risk and is not a safe substitute for smoking cigarettes.
Health Effects
Smokeless tobacco contains 28 cancer-causing agents (carcinogens). It is a known cause of human cancer, as it increases the risk of developing cancer of the oral cavity. Oral health problems strongly associated with smokeless tobacco use are leukoplakia (a lesion of the soft tissue that consists of a white patch or plaque that cannot be scraped off) and recession of the gums.
Smokeless tobacco use can lead to nicotine addiction and dependence.
Adolescents who use smokeless tobacco are more likely to become cigarette smokers.
