Chemicals

      Each cigarette contains over 4000 chemicals, and at least 43 of those are known to cause cancer. The addictive drug in cigarettes is Nicotine. People smoke to reduce the craving for nicotine, which is a poisonous stimulant. A stimulant is a drug that increases the action of the central nervous system, the heart and other organs. Tar and Carbon monoxide are also ingredients in cigarettes.
