Smokeless Tobacco and How to Quit

Many terms are used to describe smokeless tobacco products, such as oral, chewing, snuff, spit, and spitless tobacco. All forms of oral tobacco have chemicals known to cause cancer (carcinogens). These products can cause cancer of the mouth, pancreas, and esophagus (the tube that carries food from the mouth to the stomach). Oral and smokeless tobacco also cause many other health problems, such as gum disease, destruction of the bone sockets around the teeth, and tooth loss. They cause bad breath and stained teeth, too.
