Aztec tobacco

''Nicotiana rustica'', Aztec tobacco or strong tobacco, called ucuch in southern Mexico due to its Mayan roots, mapacho in South America, Bauerntabak in Germany, and thuoc lao in Vietnam, is a rainforest plant in the family Solanaceae. It is a very potent variety of tobacco, containing up to nine times more nicotine than common species of ''Nicotiana'' such as ''Nicotiana tabacum''.
