Tobacco

Tobacco is produced from the processed leaves of a leafy plant in the nicotiana genus of fauna and has been used in human communities for thousands of years for ceremonial, medicinal, and recreational purposes. All methods of tobacco consumption result in varying quantities of nicotine being absorbed into the user's bloodstream which creates a biological dependence on the substance. Tobacco may be smoked, sniffed, or placed directly into the mouth for absorption of the nicotine.
