Nicotiana rustica L.

Nicotiana rustica, Aztec tobacco or wild tobacco, in the southern part of México specifically Campeche and Yucatán, it is called Ucuch due to its mayan roots, known in South America as mapacho and in Vietnam as thuoc lao (thuốc lào), is a rainforest plant in the Solanaceae family. It is a very potent variety of tobacco. The high concentration of nicotine in its leaves makes it useful for producing pesticides.

Nicotiana rustica is often used for entheogenic purposes by South American shamans. It contains up to nine times more nicotine than common species of Nicotiana such as Nicotiana tabacum (common tobacco). Other reasons for its shamanic use are the comparatively high levels of beta-carbolines, including the harmala alkaloids harman and norharman. Most commonly, in South American ethnobotanical preparations, it is allowed to soak or be infused in water, and the water is then insufflated into the stomach in a preparation known as singado or singa; it is also smoked in cigars, used as an enema, made into a lickable product known as ambil, and made into a snuff with the bark of a species of Theobroma, creating nu-nu. In the southeast part of Turkey, people use this herb and ashes of some tree bodies to make a moist snuff called maraş otu. They use this by putting the mixture under their lips like Swedish snus or Afghan naswar. It is also a common admixture of Ayahuasca in some parts of the Amazon.
