Tobacco refers to the leaves of the tobacco plant that have been dried and processed for people to roll up and smoke. Tobacco is the main ingredient in cigarettes, and of course, chewing tobacco.
Tobacco was used for fun in the Americas way before the Europeans came, but it was cultivated in France in the 1500s, and is still going strong. The word tobacco probably came from the Caribbean. The name Tobacco Road is from a novel by Erskine Caldwell, but is used to describe a section of North Carolina that produced a lot of tobacco. Tobacco is mainly used in cigarettes, which are really bad for your health.
