Use of classic hallucinogens does not, however, produce tolerance to drugs that do not act directly on the same brain cell receptors. In other words, there is no cross-tolerance to drugs that act on other neurotransmitter systems, such as marijuana, amphetamines, or PCP, among others.
Furthermore, tolerance for hallucinogenic drugs is short-lived—it is lost if the user stops taking the drugs for several days—and physical withdrawal symptoms are not typically experienced when chronic use is stopped.
The long-term residual psychological and cognitive effects of peyote remain poorly understood. Although one study found no evidence of psychological or cognitive deficits among Native Americans who use peyote regularly in a religious setting, those findings may not generalize to those who repeatedly abuse the drug for recreational purposes Halpern, Peyote users may also experience hallucinogen persisting perception disorder HPPD —also often referred to as flashbacks.

Historical Background The hallucinogenic properties of certain mushrooms have been known for centuries. The discovery of mushroom sculptures in ancient Central and South American ruins suggests that hallucinogenic mushrooms were used by native people during religious ceremonies. The Aztecs used the term "teonanacatl" meaning "flesh of the gods" to describe hallucinogenic mushrooms.
Historians have proposed that Aztec spiritual leaders used these hallucinogens to induce an altered state of consciousness that they believed would allow them to communicate with their gods and other spirits.
