Nicotiana Tabacum is a plant species in the Solanaceae family. It is commonly known as tobacco, and is cultivated worldwide for commercial purposes. The plant is high in nicotine, a potent central nervous system stimulant, and is used for smoking, chewing, and snuffing. The leaves of the plant are cured by a process that involves heat and exposure to air, resulting in the production of tobacco products such as cigarettes, cigars, and chewing tobacco. Synonyms for Nicotiana Tabacum include tobacco plant, smoking tobacco, leaf tobacco, and cigar tobacco. Other related terms include nicotine, tar, and carcinogens, all of which are associated with the health risks associated with tobacco use.
