Although only LSD showed affinity to dopaminergic D1-3 receptors , other studies demonstrated that the characteristic behavioral effects of mescaline in cats were nearly completely blocked by pretreatment with low doses of either serotonin (methysergide) or dopamine (haloperidol) specific antagonists . Interestingly, aiming to enhance the psychedelic effects of peyote, the participants of religious ceremonies usually fast to increase gastrointestinal absorption of the drug. As shown in Table 3,there were several differences across the four mescaline subgroups, whereinthose in the Peyote subgroup reported consuming more doses (2.9) in their mostmemorable experience compared to all other subgroups. Regarding abuse potential, most respondents (55%) indicated that they neverconsumed more than one dose of mescaline in a session, and approximatelyone-third (32%) reported that they have consumed mescaline with other substanceson one or two occasions. As with other psychedelics, the main adverse effects of mescaline are psychologicaland include anxiety, panic, and disorganized behavior (Cohen, 1960). For individuals with a history of mental health disorders, especially psychosis, the use of psychedelic substances like mescaline can exacerbate symptoms.
- Nausea and emesis were frequent adverse effects at the 800 mg dose.
- Anecdotally, mescaline is said to often produce a dreamlike state of profound wonder.
- Cross tolerance of mescaline with other serotonergic drugs such as LSD and psilocybin has been described in humans and other animals ; mescaline tolerance develops after a few days of consumption but sensitivity is restored after 3-4 days of drug abstinence 43, 61.
- Improvement in mental well-being and its ability to overcome alcoholism render mescaline potentially beneficial in clinical settings.
- Mescaline-containing cacti have been used in this region as a sacramental medicine for thousands of years, and spread into more mainstream Western use in the late 19th century.
- Allegedly, they considered it to be a divine substance with healing properties 7, 8, 1.
We can’t say whether mescaline improves mental health due to flaws in the published research. It’s important to note that mental health was not measured before peyote use started so we don’t know how (or if) it changed over time. According to the study, peyote users reported what was eminem addicted to better psychological well-being and more positive emotions .
Understanding the Cultural and Traditional Use of Mescaline
However, mescaline also caused schizophrenic patients to become highly sexual, verbalizing sexual desires and past experiences. There have been a few clinical trials examining the effects of mescaline in chronic schizophrenics. Psychiatrist Humphry Osmond, who used mescaline in his practice, noted that people who had hepatitis experienced prolonged responses to mescaline .
Then in 1919, Austrian chemist Ernst Späth found a way to make mescaline in the lab. Scientific interest in peyote took off at the end of the 19th century after American newspaper reports of the ritualistic use of peyote by Native American tribes. Allegedly, they considered it to be a divine substance with healing properties 7, 8, 1. One estimate suggests that Native Americans in Mexico used peyote as far back as 5,700 years ago. According to some researchers, mescaline is one of the oldest known hallucinogens used by humans . It is also found in varying degrees in many other members of the cactus family .

For example, older adults national institute on alcohol abuse and alcoholism niaaa mescaline is more likely to distort the user’s body image, while the loss of control of thoughts is more commonly reported on LSD . However, users do report slightly different subjective experiences, suggesting they may work differently in certain aspects. Because they share the same mechanism of action, mescaline and LSD have very similar effects. Remember that LSD is also still classified as an illegal drug (Schedule I substance).
What is Mescaline? Emerging Research, Risks & Side Effects
The peak effect of mescaline (800 mg) on heart rate and body temperature was significantly reduced by ketanserin (Fig. 3 and Supplementary Table S1). The peak blood pressure responses to mescaline were not significantly reduced by ketanserin because the onset of the effect of ketanserin occurred after the mescaline-induced increase in blood pressure. Co-administration of ketanserin reversed the mescaline-induced elevations of blood pressure and heart rate. Mescaline increased diastolic and systolic blood pressure at 200–800 mg compared with placebo and independent of dose. Adverse effects are listed in Supplementary Tables S1 and S3.
It is crucial for those considering the use of mescaline to be fully aware of its psychoactive properties and the potential legal and health risks. The effects of mescaline are often compared to those of LSD and psilocybin, although with distinct variations in visual, auditory, and sensory perception. With more research into compounds such as mescaline, more potential uses may arise. However, an overdose resulting in death is very unlikely with this substance. This current lack of evidence is due, in part, to the fact that peyote is a Schedule 1 drug in the U.S.
- In summary, both sources of mescaline have unique concerns and considerations.
- Mescaline is not physically addictive, but like other hallucinogenic drugs, you can become tolerant to its effects.
- No order effects were observed in the subjective response to mescaline, except for nausea.
- Peyote cacti are small button-shaped cacti that hide underneath desert shrubs.
- Frequent acute adverse effects included fatigue, headache, lack of concentration, and nausea (Supplementary Table S3).
- Mind Medicine, Inc. had no role in planning or conducting the present study or the present publication.
In medium to high doses, mescaline can initiate insightful experiences, visual alterations, and emotional sensations. The positive effects of mescaline are similar to other psychedelic substances. Today, mescaline is used recreationally for psychedelic effects, for healing experiences and consciousness work, and in continued traditional cultural uses among some Indigenous groups.

In traditional and ritualistic practices of Indigenous communities, mescaline is derived from fast-growing San Pedro cacti and slow-growing peyote cacti. Mescaline is unique compared to other classical psychedelics due to its distinct molecular structure, effects, and classification as a phenylethylamine3. Finally, while hallucinogens are widely used, both by drug abusers and by members of traditional cultures for religious or healing purposes, the long-term residual psychological and cognitive effects of these drugs remain poorly understood. Moreover, it is important to remember that abuse of peyote cactus may escape detection during routine drug testing, making clinical and forensic diagnosis difficult. Considering the human dose range reported above, it would be very difficult to consume enough mescaline to cause death. The dog seems to be the most sensitive species and in humans the lowest toxic dose has been extrapolated from data obtained in laboratory animals at 2500 μg/kg (i.m.) with reported effects of euphoria, distorted perceptions and hallucinations.
The extant area of the San Pedro cacti encompasses Ecuador and Peru. San Pedro cacti grow in tubular clusters and usually average between 3 to 6m in height. They can easily fit in the palm of your hand, and the extant area of Peyote cacti extends from northern Mexico to southern Texas.
The impact of mescaline on mental health is unknown due to a lack of quality clinical data. Remember that mescaline is classified as an illegal drug with a high potential for harm. Common to all psychedelics, mescaline can alter the user’s concept of self. However, mescaline in the form of peyote is legal for religious use by members of the Native American Church (NAC). In the 1950s, British psychiatrist Humphry Osmond began studying mescaline and LSD’s ability to address mental illnesses, including alcohol addiction.
There is an exception for the Native American Church which uses peyote in religious practice. In the United States, mescaline is a Schedule I controlled substance; therefore, it is illegal to use recreationally. Beginners are advised to take lesser doses so that they get an idea about their tolerance.
By activating this receptor, mescaline can produce temporary changes in the brain that mimics those seen in psychotic episodes caused by schizophrenia 58, 59, 60, 23, 24. The long-term risks of mescaline are unknown since proper clinical data are lacking. Some researchers suggest that taking mescaline in a safe and familiar environment may help reduce the risk of harm, but this has never been verified in human studies . There is one case report of an individual under the influence of mescaline who died of an accidental fall while experiencing hallucinations. There have also been sporadic reports of members of the Native American Church using peyote to prevent alcohol abuse . A couple of clinical trials suggested that LSD has the potential to help with alcoholism, but large-scale data are lacking .
All these addiction recovery facilities will accept your Indian healthcare treatment plan. If you are addicted to mescaline, seek treatment immediately. Any substance can be abused.
The second examines the serotonin 2A receptor’s role in how mescaline induces altered states of consciousness. The program grants access to healthcare professionals treating patients with serious or life-threatening conditions. The authors point out that traditional use in the NAC does not reflect how mescaline might be used recreationally, and so the findings should not be generalized to all long-term mescaline consumption. One study from 2005 found no evidence that long-term use among Native Americans led to psychological or cognitive deficits. Due to the illegal status of mescaline, research is sun rock thc level lacking on the general safety and toxicity profile of the compound, though new efforts are focused on carrying out this basic research (covered in the Current Research Landscape section). Psychedelics produce their effects by impacting neurotransmitters in the brain, including serotonin, dopamine and norepinephrine.
The half-life of any given substance is the time needed for only 50% of a substance to remain in the body. The plasma half-life of mescaline is approximately 6 hours. Since mescaline can bind with dopamine receptors, it has a slight possibility of forming physical dependencies, though this has yet to be formally studied. While the geographic range of San Pedro cacti is considered of “little concern” to conservationists, the geographic range of Peyote cacti is considered “vulnerable.” Mescaline is the active ingredient in Peyote and San Pedro cacti. Psychedelics are a class of drugs which is known to change the user’s mood, thoughts, or perceptions.
