There are two main types of smokeless tobacco: chewing and snuff.
Chewing tobacco comes in leaf tobacco (packaged in a pouch) or plug tobacco (in brick form) and both are put between the cheek and gum. Users keep smokeless tobacco in their mouths for several hours to get continuous nicotine in the tobacco.
Snuff is a powdered or finely ground tobacco (usually sold in cans) that is put between the lower lip and the gum. Just a pinch is all that's needed to release the nicotine, which is then swiftly absorbed in the bloodstream, resulting in a quick high.

Quitting Smokeless Tobacco
Quitting smokeless tobacco is a lot like quitting smoking.Both contain nicotine and both involve the physical and psychological components of addiction.
Two elements are unique for smokeless users, however:
There is often a stronger need for oral substitutes to take the place of the chew or snuff.
Because spit tobacco often causes sores in the mouth and gum problems, the disappearance of these after quitting provides a readily visible benefit.
