Cigarette is a roll of shredded tobacco wrapped in paper. Nearly all cigarettes smoked in the United States are a blend of tobaccos grown inside the country or imported. They contain chiefly flue-cured tobacco, which is grown in Florida, Georgia, North Carolina, South Carolina, and Virginia; burley tobacco, which is grown mainly in Kentucky and Tennessee; imported oriental tobacco, which mostly is grown in Greece and Turkey; and a small amount of Maryland tobacco. Some cigarettes contain flue-cured and burley tobaccos imported from Argentina, Brazil, Canada, and Malawi. They may also contain reconstituted sheet tobacco, which is made from ground leaf stems and leaf pieces. The tobacco blend is sprayed with flavorings and a chemical that preserves moisture. Most cigarettes have a filter at one end.
