Nicotiana tabacum
: A South American herb whose leaves contain 2-8% nicotine and serve as the source of smoking and smokeless tobacco. Nicotiana tabacum presents a huge health problem. Disease and premature death continue to be caused by the use of tobacco. About 50 million Americans smoked in the year 2000. Of those who quit, 90% do so on their own. But in a given year, only about 1.7 million American smokers (3.6%) stop smoking.
