ABSTRACT
Cocaine is certainly not the only plant that contains psychoactive alkaloids; at least four other species contain alkaloids capable of producing amphetamine-like effects, and a number of other New World plants contain potent hallucinogens. Four species contain alkaloids that behave more like stimulants than like hallucinogens: absinthe, caffeine, khat, and ephedra. The latter two compounds are both classified as phenethylamines.
