It has been smoked in one form or another since about 2000 BC. There are pictoral drawings of ancient Mayans smoking crude cigars from 1400 BC. Tobacco has a very long history of use in Native American culture and played an important part in the foundation of the United States of America, going back to colonial times and the original Jamestown settlement.
