Tobacco is a plant that can
be smoked in cigarettes, pipes, or cigars. It's the same plant that's in smokeless
tobacco, known as dip, chew, snuff, spit, or chewing tobacco. Nicotine is addictive,
which means you will become so used to it that you'll need to have it just to feel
OK. On top of all that, nicotine and other chemicals in tobacco cause diseases, including
lung problems, heart disease, and some kinds of cancer.
