What is inside coca leaves?

Coca leaves contain several alkaloids, the most notable being cocaine, which is a powerful stimulant. In addition to cocaine, coca leaves also contain other compounds such as ecgonine, benzoylecgonine, and various vitamins and minerals. Traditionally, indigenous people in South America have chewed coca leaves for their stimulant effects and to alleviate altitude sickness. However, the leaves are also the primary source for the illegal production of cocaine.
