Smokeless tobacco is commonly taken in two forms:
- Snuff is a finely ground form of tobacco. Moist snuff (sometimes in a sachet) is placed between the lower lip and gum. Nicotine from the snuff is absorbed through the skin inside the mouth. Dry snuff is a powder that is taken orally or is sniffed into the nose.
- Chewing tobacco typically consists of wads of loose leaf tobacco. Nicotine from the tobacco is absorbed through the skin in the mouth.
Smokeless tobacco is not considered a safe substitute for smoking cigarettes.
