Throat cancer and smokeless tobacco? i read that using smokeless tobacco can cause throat cancer. i only use it once in a while. is that ok?

No. Smokeless : No. Smokeless tobacco causes cancer of the tongue, mouth, and throat, and may also cause cancers of the stomach and intestine. These are extremely difficult cancers to treat. Most are fatal, and those that are cured leave patients with terrible deformities. Even if it doesn't cause cancer, smokeless tobacco causes gum disease that may cost you your teeth. You say you use it only once in a while, so it will be easier to quit now. If you wait, chances are that you'll start using it more in the future.

The less the better: Smokeless tobacco causes all the ingredients, including cancer-causing tars, to dissolve in saliva and are distributed around the mouth, tongue, lips, throat and upper pharynx, and can cause cancer in any or all of those places. The more you chew, sniff, tuck in your gums etc etc., the greater the chance of cancer. If once in a while is once or twice a month, probably low risk- 3x/week its more.
