peyote

Peyote is a small spineless cactus native to Mexico and the southwestern United States, containing mescaline and other psychoactive alkaloids.

The plant has been used for centuries in Indigenous spiritual ceremonies.

Eating peyote buttons—the rounded tops of the cactus—produces vivid hallucinations and altered states of consciousness.

Its religious use is legally protected for members of the Native American Church in the United States.
