In its original use, the plant medicine was also used to treat a number of ailments, including snake bites, wounds, skin conditions, and general pain. Pure mescaline is usually available as a white or brownish crystalline powder, either loose or packed into capsules as a pill. However, compared to other psychedelics, mescaline extraction tends to be rare in most parts of the world. Mescaline is a psychedelic hallucinogen obtained from the small, spineless cactus Peyote (Lophophora williamsi), the San Pedro cactus, Peruvian torch cactus, and other mescaline-containing cacti. It is also found in certain members of the Fabaceae (bean family) and can be produced synthetically.
Is it dangerous to mix with other drugs?
Mescaline was first isolated from a sample of the sacramental peyote cactus in 1896. It was the first psychedelic drug to be synthesized in 1919 by a German chemist named Arthur Heffter. During the early 20th century, mescaline rose to prominence in Europe, first in Germany, and later as a research chemical for psychedelic research studies in the United States and Canada. One prominent figure in these studies, psychiatrist Humphrey Osmond, shared mescaline with Aldous Huxley, who would later write about his experiences in several books.
Mental health risks
- Other traditional uses of cacti containing mescaline include healing and divination.
- By the 1950s, with psychiatry’s biomedical turn, it was being widely used in schizophrenia research, the context in which Huxley encountered it.
- Mescaline has unique effects compared to serotonin 2A receptor agonists like psilocybin and, in many ways, can induce effects similar to adrenaline, such as nausea and increased heart rate.
- Indigenous people desire to ensure that their culture, identity, and sacred traditions around these plants are protected while psychedelics become mainstream.
- Today, members of the NAC report using Peyote anywhere from once per year to two tothree times per week (Dasgupta,2019).
Though not considered addictive, mescaline may still pose other health risks if abused. Mescaline is a naturally occurring psychoactive alkaloid that is the main psychedelic compound in a range of psychedelic cacti native to the Americas, including peyote, San Pedro, and Peruvian Torch. In its natural state, mescaline has been used in Native American religious and shamanic ceremonies for thousands of years. People have used hallucinogens for hundreds of year, mostly for religious rituals or ceremonies.
MeSH terms
- (Huxley thought thespelling should be ‘psychodelic’ and persisted with it, to little avail.) Hisessay on the experience, The Doors ofPerception (1954), kickstarted the psychedelic era.
- It is also worth noting that these effects will not necessarily occur in a predictable or reliable manner, although higher doses are more liable to induce the full spectrum of effects.
- Drugs that affect a person’s mental state (psychoactive drugs) can also have varied effects depending on a person’s mood (often called the ‘set’) or the environment they are in (the ‘setting’).
- Polydrug use is a term for the use of more than one drug or type of drug at the same time or one after another.
- Keep in mind that these compounds have a different molecular weight, meaning the dosage will be different between the two.
It may take 10 or more years for a single peyote cactus to transition from a seedling to mesclun psychedelic the first stage of flowering. Peyote (Lophophora williamsii) has been traditionally consumed by Indigenous North American tribes for at least 5,500 years. The crowns of the cacti growing above ground are called the peyote buttons, which are carefully harvested to allow the plant to continue to grow. Peyote, in its natural form, contains dozens of different types of phenylethylamine alkaloids, some of which are pictured above. It is possible that different kinds of cacti containing various constituents could result in distinct experiences, similar to how cannabis strains produce a variety of subjective effects5.
The pharmacology of mescaline has been assessed in animal models (Bevan et al., 1974; Darvesh and Gudelsky,2003; Kyzar et al.,2012; Nichols,2004), and the subjective effects have been reported in numerous casestudies (Frederking,1955; Halpern,1961; Klüver,1926; Osmond andSmythies, 1952). People with heart conditions or uncontrolled high blood pressure should avoid using mescaline. If you have any health issues, always consult your doctor before taking a psychedelic substance. However, due to its unique pharmacology, the mescaline experience is distinguishable from other altered states. In traditional and ritualistic practices of Indigenous communities, mescaline is derived from fast-growing San Pedro cacti and slow-growing peyote cacti. Peyote cacti were first introduced to Western culture when Spanish people arrived in Mexico in the early sixteenth century.
Are Mescaline and Peyote the Same Thing?
During World War II, the Nazis notoriously experimented on prisoners with drugs such as mescaline. Nazi physician Kurt Plötner dosed concentration-camp prisoners with mescaline at random to see whether it had any effect as a truth serum. Mescaline experiments were also performed in the United States under a secret program run by the CIA called MK-Ultra. Dr. Plötner was recruited by Robert Hyde, a psychiatrist who oversaw covert studies in Boston, to help the United States test experimental materials like LSD and mescaline on consensual — and unsuspecting patients and prisoners. Mescaline (at both doses), LSD, and psilocybin similarly increased pupil size compared with placebo (Supplementary Fig. S3, Supplementary Table S5).
Given the renewed interest in psychedelic substances, systematic comparisons of their acute subjective effects, autonomic effects, and pharmacokinetics are crucial. The present study was the first to compare three classic psychedelics with a randomized, double-blind, placebo-controlled, within-subject design and the first to establish equivalent doses. These numbers are similar to reports from 5-MeO-DMT users (Davis et al., 2018) andrelatively low in comparison to reported craving for more widely used substances(e.g. alcohol) (McCabe et al.,2017). Consistent with prior research (Johansen and Krebs, 2015; Krebs and Johansen, 2013),these findings may indicate that mescaline has a relatively favorable psychologicalsafety profile for the use in naturalistic settings as evidenced by reports of lowabuse liability. However, it is possible that people who have had negativeexperiences with mescaline might have been less likely to have seen or responded tothe present survey, which could have biased our findings. Additionally, definitivesafety profiles that include the assessments of vital signs, blood pressure, andelectrocardiography (ECG) need to be established in laboratory studies of mescalineadministration.
Psychologists and neurologists, particularly in Germany, conducted trials on dozens of subjects that generated hundreds of pages of reports of dazzling visions, bizarre sensations and cosmic revelations. Avant-garde painters worked under its influence, and it was administered under clinical supervision to philosophers such as Jean-Paul Sartre and Walter Benjamin. By the 1950s, with psychiatry’s biomedical turn, it was being widely used in schizophrenia research, the context in which Huxley encountered it.

How long does mescaline last?
In the 1890s, aesthetes and poets such as Havelock Ellis and WB Yeats experimented with it, looking at art objects and listening to music under the influence. In the 1930s, avant-garde artists painted on it, and psychiatrists gave it to intellectuals like Walter Benjamin and Jean-Paul Sartre. Sartre had a very unpleasant experience, after which he believed he was being followed around by crabs that nobody else could see.
