As shown in Table 2,most respondents (66%) had consumed San Pedro in their lifetime, with smallerproportions of respondents having ingested Peyote (36%) and synthetic mescaline(31%). Overall, respondents reported that they had the most experience with SanPedro (45%). Almost all respondents reported that they had consumed mescalinethrough oral ingestion (97%), very small proportions reported ingesting bysnorting (1%) or via sublingual administration (2%), and most (67%) reportedthat they last consumed mescaline at least 6 months, prior to surveyparticipation.
- The cactus produces flowers sporadically; these are followed by small edible pink fruit.
- Mescaline is a naturally occurring psychoactive phenethylamine found inseveral cacti and historically used ceremonially by Indigenous and LatinAmerican populations.
- Other minor metabolites have been identified in human urine, such as N-acetyl-3,4-dimethoxy-5-hydroxyphenylethylamine, 3,4,5-trimethoxybenzoic acid, 3,4-dimethoxy-5-hydroxyphenethylamine, and 3,4-dihydroxy-5-methoxyphenacetylglutamine [66].
- Cross tolerance of mescaline with other serotonergic drugs such as LSD and psilocybin has been described in humans and other animals [61]; mescaline tolerance develops after a few days of consumption but sensitivity is restored after 3-4 days of drug abstinence [43, 61].
- This section also asked about dose, source, and preparation, aswell as how many people were present during the session and whether theywere also consuming mescaline.
- However, compared to other psychedelics, mescaline extraction tends to be rare in most parts of the world.

This is related to ketamine which is used as a dissociative anaesthetic (see Chapter 11 and 11.3c). In fact, phencyclidine was developed as a potential anaesthetic agent dmt n, n-dimethyltryptamine origins, effects and risks and was marketed under the name ‘Sernyl’. However, it was withdrawn because of the psychotomimetic effects, particularly hallucinations, which appeared during recovery.
Data availability
LSD showed a significantly lower maximal diastolic blood pressure response compared with psilocybin. Conversely, LSD showed a trend toward an increase in heart rate compared with psilocybin. The data are expressed as the mean ± SEM of maximum responses in 32 participants for LSD and psilocybin and in https://sober-house.net/chip-carter-says-he-was-warned-by-white-house/ 16 participants for each mescaline dose. The intensity of acute subjective mescaline effects was examined across thesample and within each mescaline subgroup. There were no significant differences inthe ratings of the intensity of these acute subjective effects as a function ofa mescaline subgroup.
How is mescaline used or abused?
The comparison of the low and high mescaline doses was between-subjects and their allocation was neither random nor blinded. The study used a highly controlled hospital setting and included only healthy participants, most of whom were experienced psychedelic drug users. Therefore, patients who undergo psychedelic therapy may respond differently to mescaline, LSD, or psilocybin. Lastly, our psychometric instruments may not have been sufficiently sensitive to capture the complex phenomenology of these substances. Subtle qualitative subjective effect differences between mescaline, LSD, and psilocybin may not necessarily be excluded.
These main groups include quinones (or phenolic precursors), metal complexes (or complexors), aromatic nitro compounds (or reduced hydroxylamine and nitroso derivatives), and conjugated imines (or iminium species).

Mescaline was made a Schedule I substance under the Controlled Substance Act (CSA) in 1970, making it an illegal substance with no medical benefits. This has led to some controversy as peyote is used for religious purposes by various Native American groups. When peyote is used in religious ceremonies, it is exempt from its classification as a Schedule I controlled drug under the 1994 American Indian Religious Freedom Act (AIRFA).
Buttons, Cactus, Mesc, Peyoto,
Although mescaline activates the serotonin 5-HT2A receptor, it has very different effects from other psychedelics. In many ways, it behaves like adrenaline, producing symptoms such as nausea and increased heart rate and temperature, says Rafael Lancelotta, a licensed professional counsellor and researcher at the Ohio State University in Columbus. Effects on plasma levels of oxytocin and BDNF are shown in Supplementary Fig. Mescaline and LSD significantly increased plasma oxytocin levels compared with placebo. Oxytocin levels were significantly higher after mescaline compared with psilocybin. 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).
This is due to the chemical reaction the drug has with neural pathways in the brain. Read here to find out more about mescaline highs or “trips” and the effects of peyote on the brain. The hallucinogenic effects of mescaline will last longer for some people than others. Depending on a person’s height, weight, mental state, previous drug use, mescaline can last between 10 and 20 hours. Mescaline is a naturally occurring psychedelic hallucinogen that is found in certain species of cacti located in South America and parts of North America. Mescaline has been used as part of religious ceremonies for thousands of years, as well as recreationally in more recent times.
Most respondents (65%) reported that their first use of mescalineoccurred between the ages of 18 and 30, and almost one-half (46%) reported thatthey have used mescaline a total of one to three times in their lifetime, withapproximately one-quarter (23%) reporting lifetime use of more than 11occasions. One-half of respondents reported thatthey primarily consumed mescaline outdoors (47%), and three-quarters reportedthat they consumed mescaline without oversight of another person (i.e.self-administering the mescaline) (78%). The half-life of ingested mescaline in humans is about 6 hours [68] and in the mouse brain was found to be approximately 1 hour [71]. Charalampous et al. [68] reported that, following an oral administration of mescaline to humans, 81.4% is eliminated unchanged in urine within the first hour, and 13.2% of the dose is excreted as 3,4,5-trimethoxypheny-lacetic acid (TMPA), with increasing elimination of this metabolite over the course of time. Accordingly, 87% of TMPA was excreted within the first 24 hours and 96% within 48 hours [68].
In those species, mescaline is present only in trace concentrations, not necessarily high enough to produce pharmacological effects following ingestion of the cactus. Peyote contains a large spectrum of phenylethylamine (or phenethylamine or β-phenylethylamine) alkaloids, the principal being mescaline for which the content of Lophophora williamsii is about 0.4% fresh (undried) and 3-6% dried [28, 42]. Besides mescaline, dozens of different alkaloids have already been identified in this cactus (Fig. 33) [43-46].
In fact, a person who has a tolerable experience one day could have a terrible one the next day.

The process entails dephosphorylation to the phenol followed by oxidation to quinone-type products.
The relative absence of information about the scope of mescaline use limitsunderstanding of the safety profile of this substance, which is needed to inform thedesign of future studies with this compound. Therefore, the primary aim of thisstudy is to examine the epidemiology of mescaline use (patterns and motivation foruse, subjective effects, and potential medical and psychological harms/benefits as aresult of consumption) among English-speaking adults who have consumed mescaline atleast once in their lifetime. As a secondary aim, we examined whether there werechanges in medical and psychological functioning following mescaline use. The finalaim involved examining differences in the subjective effects and the patterns andmotivations of use as a function of the type of mescaline consumed (i.e. synthetic,extracted, Peyote, or San Pedro). Symptoms of mescaline poisoning are consistent with a sympathomimetic toxidrome, namely hyperreflexia, tachycardia, agitation, muscle stiffness, ataxia, seizures, mydriasis, sialorrhea, hyperthermia and paresthesia [10, 61, 93]. The methoxy side chains are likely responsible for the hallucinogenic effects of mescaline and are found in similar compounds that are known hallucinogens, including the “designer” street drug 2,5-dimethoxy-4-methylphenylisopropylamine (also known as STP or DOM) [94].
Plasma BDNF levels were measured at baseline and 3, 6, and 12 h after drug administration. Peyote buttons are most often chewed, but they can also be mixed with water and swallowed. Sometimes mescaline is made into a powder and put into capsules and swallowed. Mescaline comes from button-shaped seeds found in the peyote cactus and also from some other members of the Cactaceae plant family and from the Fabaceae bean family.
