Native to the southwestern US, peyote is a spineless cactus whose active substance is mescaline, a naturally occurring hallucinogenic drug. Ritually ingested by indigenous people in Mexico and the US to produce visions, the plant is chewed, brewed for drinking, or rolled into pellets to be swallowed. Apart from its use by Native Americans in religious ceremonies, peyote is illegal in all 50 US states. Based on archaeological specimens, how long has peyote been used by Native Americans? Discuss
