What is smokeless tobacco?

There are two types of smokeless tobacco––snuff and chewing tobacco. Snuff, a finely ground or shredded tobacco, is packaged as dry, moist, or in sachets (tea bag–like pouches). Typically, the user places a pinch or dip between the cheek and gum. Chewing tobacco is available in loose leaf, plug (plug–firm and plug–moist), or twist forms, with the user putting a wad of tobacco inside the cheek. Smokeless tobacco is sometimes called "spit" or "spitting" tobacco because people spit out the tobacco juices and saliva that build up in the mouth.
