Nicotiana rustica, known in South America as Mapacho, is a 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 creating organic pesticides. In Russia, N.rustica is called "makhorka" (махорка). It was smoked casually by the lower classes before normal tobacco became widely available (after World WarI I), and is still sometimes smoked by peasants and farmers. Nicotiana rustica leaves have a nicotine content as high as 9%, whereas Nicotiana tabacum (common tobacco) leaves contain about 1 to 3%.
