What is peyote?

Lophophora Williamsii is more well-known as peyote. It is a spinless cactus native of the Chihuahan desert, specifically in an area between southern Texas and San Luis Potosi in northern mexico. Its popularity comes from its alcaloid concentration, mostly mescaline. It has been an item of commerce for a very long time, overharvesting during the last 100 years and the fact that peyote is really slow growing in the wild ended in the fact that now the cactus lophophora is an endangered specie. Its sale is now restricted by law to members of the Native American Church.


The chemical mescaline was first isolated only about 100 years ago. The use of peyote by native american is very old, nobody knows exactly but some scientists claims that its known history dates back to as early as 5000 B.C. In 1966 the federal government acted to regulate and outlaw a natural living organism, the peyote as it already did to others such as marijuana or psilocybe mushroom not to mention it.

Peyote (Lophophora williamsii or Lophophora diffusa) is a spineless cactus with small protrusions called “buttons” that are used for psychoactive hallucinogenic purposes. Mescaline, an amphetamine, is the principal active psychedelic compound in peyote. It is a hallucinogen derived from several different cacti— the Peyote cactus that grows in the southwestern United States and Mexico, the San Pedro cactus (Trichocereus pachanoi) found in Peru, or the Peruvian Torch cactus (Trichocereus peruvianus). The limited growing area of this cactus restricts drug supply severely, so it is a common practice to sell other drugs such as PCP or LSD as mescaline. Mescaline can also be produced in a laboratory by chemical synthesis. A white crystalline material, mescaline sulfate, is the pure form of mescaline and can be put in capsule form. Peyote and mescaline are listed as Schedule hallucinogens under the Controlled Substances Act in the United States. In a rare exception, “the nondrug use of peyote in bona fide religious ceremonies of the Native American Church, and by members of the Native American Church” is legal.

History of peyote

Peyote is one of the oldest psychedelic agents known. Aztecs of Pre-Columbian Mexico who considered the cactus magical and divine often used it. Peyote use then spread from Mexico to North America to other Native American groups who used it to treat illnesses, communicate with spirits, and for highly religious ceremonies. In 1918, The Native American Church was formed to preserve their right to use peyote.

Mescaline has been used for centuries because of the mystical experiences that it is purported to induce. Until the landmark free exercise decision handed down by the U.S. Supreme Court in Employment Division v. Smith 494 U.S. 872 (1990), members of the Native American Church had the legal right to use mescaline-containing peyote in religious ceremonies. Ernst Spath first synthesized mescaline in 1919.

Methods of Use

Live plant

The peyote cactus contains buttons that can be cut from the root and dried. The buttons can either be chewed or soaked in water to produce an ingestible liquid. Peyote buttons may also be ground into a powder and then “smoked with a leaf material, such as cannabis or tobacco.”

Mescaline (extract)

Mescaline is administered orally in the form of powder, a tablet, a capsule, or liquid. In its pure liquid form, mescaline can be injected, however, this method is unpopular. Users typically consume between 300-500 mg (which is approximately the amount contained in 3-6 peyote buttons). Effects generally appear within 1-2 hours, and gradually disappear 10-12 hours after administration.


Mescaline belongs to a family of compounds known as phenethylamines, making it quite distinct from the other major psychedelics such as LSD and psilocybin, which belong to the indole family. Many synthetic “designer” psychedelics, such as ecstasy (MDMA) and 2C-B, are phenethylamines, and are related to the chemistry of mescaline. The chemical structure of mescaline is very similar to that of the neurotransmitters dopamine and norepinephrine, thus the drug can interfere with their actions in the brain.


Mescaline produces perceptual, cognitive, and emotional experiences that vary widely among users based on dose size, setting, expectations, personality, and drug history. The only documented long-term effect of mescaline is a possible prolonged psychotic state similar to that of paranoid schizophrenia. It is suggested that this may only affect those who were previously diagnosed as mentally ill.

Physical effects:

Numbness, tension, anxiety, rapid reflexes, muscle twitches and weakness, impaired motor coordination, dizziness, trembling, dilation of the pupils
Increased blood pressure and heart rate
Intense nausea and vomiting
Appetite suppression
Elevated body temperature and sweating
Chills and shivering
Psychological Effects

Vivid mental images and distorted vision
Synesthesia: perception of seeing music or hearing colors
Altered space and time perception
Joy, exhilaration, panic, extreme anxiety, or terror
Distorted sense of body (users can feel either weighed down or weightless)
Heightened sensory experiences (i.e. brighter colors, sharper visual definition, increased hearing acuity, more distinguished taste)
Difficult focusing, maintaining attention, concentrating, and thinking
Loss of sense of reality; melding past experiences with present
Preoccupation with trivial thoughts, experiences, or objects
Highly adverse reactions (“bad trip”), including frightening hallucinations, confusion, disorientation, paranoia, agitation, depression, panic, and/or terror

Addiction and Tolerance

Tolerance to peyote or mescaline typically develops rapidly with repeated daily use, generally within 3-6 days. Cross-tolerance may also occur with other drugs including LSD and psilocybin. With a period of abstinence of at least a few days, “desired sensitivity is restored.” Currently, no physical dependence or psychological dependence has been reported, although it may be possible.
