Coca is any of the four cultivated plants in the family Erythroxylaceae, native to western South America. Coca is known for its psychoactive alkaloid, cocaine. The plant is grown as a cash crop in Argentine Northwest, Bolivia, Colombia, Ecuador, and Peru, even in areas where its cultivation is unlawful. There are some reports that the plant is being cultivated in the south of Mexico as an alternative to smuggling its recreational product cocaine. It also plays a role in many traditional Andean cultures as well as the Sierra Nevada de Santa Marta (see Traditional uses).
