Although the determination of psilocin levels in urine can be performed without sample cleanup (i.e., removing potential contaminants that make it difficult to accurately assess concentration), the analysis in plasma or serum requires preliminary extraction followed by derivatization of the extracts in the case of GC–MS. Ehrlich’s reagent and DMACA reagent are used as chemical sprays to detect the drug after thin layer chromatography. The drug produces a yellow color in the Marquis test and a green color in the Mandelin reagent. In particular, Shirota et al. reported a novel method in 2003 for the synthesis of psilocybin at the gram scale from 4-hydroxyindole that does not require chromatographic purification.
Street names for magic mushrooms
In many countries, including Russia, India, and South Africa, psilocybin is illegal. The substance itself is classified as a Schedule I controlled substance, while the mushrooms as a whole are not. Currently, where psilocybin-assisted therapy is legal, it is only permitted to be used in approved treatment centers and administered by licensed professionals. This has led to the increased use of psilocybin-assisted therapy in approved treatment centers.

Are a variety of Psilocybe mushrooms that make up the teonanácatl group of hallucinogenic mushrooms, including P. cubensis. They found that the psychoactive chemicals psilocybin and psilocin exhibited serotonin-like effects, however as dosage increased, these compounds acted as serotonin antagonists, psilocybin being comparable to the most potent antagonist yet discovered. Questions remain concerning the durability of psilocybin’s antidepressant effects, the scalability of its treatment delivery, and regulatory uncertainty.
The NCCIH Clearinghouse provides information on NCCIH and complementary and integrative health approaches, including publications and searches of Federal databases of scientific and medical literature. A small amount of research has looked at the use of psilocybin for anxiety and existential distress in serious medical illnesses like advanced cancer. Participants who received the psilocybin-assisted psychotherapy had fewer heavy drinking days over 32 weeks, which suggests that psilocybin may be helpful for alcohol use disorder. Other states have proposed or enacted psilocybin-specific legislation to regulate its production, sale, or supervised administration. Despite its status as a Schedule 1 controlled substance at the Federal level, possession of psilocybin has been either decriminalized or deprioritized in some states and the District of Columbia.
Cultural significance and “mystical” experiences
In addition to interacting with the serotonin receptors, psilocin is a partial serotonin releasing agent with lower potency. Psilocin’s affinity for the serotonin 5-HT2A receptor is 15-fold higher in humans than in rats due to species differences. Psilocin is a close analogue of the monoamine neurotransmitter serotonin and, like serotonin, acts as a non-selective agonist of the serotonin receptors, including behaving as a partial agonist of the serotonin 5-HT2A receptor. Diclofenac and probenecid are inhibitors of these enzymes that theoretically might inhibit the metabolism of and thereby potentiate psilocybin’s effects, but no clinical research or evidence on this possible interaction exists.
A Schedule 1 controlled substance is a drug that has been determined to lack safety even under medical supervision, has no currently accepted medical use, and has a high potential for abuse. Currently, the Drug Enforcement Administration lists psilocybin as a Schedule 1 controlled substance and possessing it is illegal at the Federal level in the United States. The FDA may also grant this designation for treatments for serious or life-threatening conditions where preliminary evidence suggests the treatment may improve the conditions substantially more than other available options. Psilocybin is a chemical that occurs in certain mushroom varieties. Dried hallucinogenics may also contain other substances, which may affect their safety profile. Current research suggests psilocybin is not addictive, and no physical symptoms occur after stopping use.
- The psychoplastogenic effects of psilocybin and other serotonergic psychedelics may be involved in their potential therapeutic benefits in the treatment of psychiatric disorders such as depression.
- Ehrlich’s reagent and DMACA reagent are used as chemical sprays to detect the drug after thin layer chromatography.
- In the 1990s, hallucinogens and their effects on human consciousness were again the subject of scientific study, particularly in Europe.
- Because of limitations in the design of the studies and the small number and health status of the people involved, the authors note that the conclusions may have been biased.
- Regular use may also cause people to become tolerant to the effects of psilocybin, and cross-tolerance occurs with other drugs, including LSD and mescaline.
Is psilocybin safe?
Often considered sacred, the mushrooms have been important for healing, divination, and spiritual rites in a number of cultures. Psilocybin mushrooms have been used for hundreds or thousands of years by Indigenous groups around the world. A growing body of research has suggested that psilocybin combined with psychotherapy may be helpful for depression in the short and medium term. Because of limitations in the design of the studies and the small number and health status of the people involved, the authors note that the conclusions may have been biased.
In 2025, numerous state-level psilocybin law reforms were introduced during legislative sessions, but only a few were ultimately passed. As discussed in the above table, legislation around the legality of personal and medicinal psilocybin use is ever-changing. It is legal for medicinal use in countries including Canada, Australia, and Denmark.
Psilocybin, found in what is colloquially referred to as ‘magic mushrooms,’ is a hallucinogenic substance that is illegal in the United States under federal law. Psilocybin mushrooms were researched from the 1950s to the 1970s by a few prominent academics, including Harvard University’s Timothy Leary and Richard Alpert (later Ram Dass). There are more than 100 psilocybin mushroom species worldwide, the majority of which are members of the genus Psilocybe. Psilocybin mushroom, any of several species of hallucinogenic fungi found across a number of genera, especially Psilocybe mexicana and P. cubensis.
Psilocybin (magic mushrooms): What it is, effects and risks
In 2023, two new Psilocybe species (Hymenogastraceae), P. ingeli and P. maluti, were described from southern Africa. Contrary to popular belief, only a minority of Psilocybe species, such as P. cubensis and P. subcubensis, grow directly on feces. Many of the species found in temperate regions, such as Psilocybe cyanescens, seem to have an affinity for landscaped areas mulched with woodchips and are actually rather rare in natural settings removed from human habitation.
- The drug was eliminated approximately 20% and 80% as psilocin O-glucuronide in different studies.
- According to a 2022 review, psilocybin may have therapeutic potential for treating depression.
- They do this through a group ritual practice where the group, or just the guide, ingests psilocybin to help extract any “toxic psychic residues or sorcerous implants” found in one’s body.
- When people take psilocybin, their bodies convert it to psilocin, a chemical with psychoactive properties similar to d-lysergic acid diethylamide (LSD), another classic hallucinogen.
- The role of CYP450 enzymes in psilocin’s metabolism seems to be small, and so considerable drug interactions with CYP450 inhibitors and/or inducers may not be expected.
- Typical side effects from the compounds include nausea, vomiting, muscle weakness, drowsiness, and euphoria.

Psilocybin – Uses, Side Effects, and More
Some psychoactive species contain baeocystin, norbaeocystin and β‐carboline monoamine oxidase inhibitors in addition to psilocin and psilocybin. After psilocybin has been ingested and dephosphorylated, to psilocin, the mechanism it uses in the brain has a direct agonist effect on the 5-HT serotonin receptors. The blue-staining species of Psilocybe are characterized by the presence of psilocin and psilocybin. Most clinical trials of psilocybin for depression have had financial conflicts of interest and significant risk of bias. Another meta-analysis, which included only RCTs, found that 25 mg was the most effective dose, relative to lower doses like 10 mg and 0.215 mg/kg body weight (~15 mg for a 70-kg person).
Group size, dose, preparation, and expectancy were important determinants of the drug response. In the early 1960s, Timothy Leary and his Harvard colleagues investigated the role of set and setting in psilocybin’s effects. In rare cases people have intravenously injected mushroom extracts, with serious medical complications such as systemic mycological infection and hospitalization. Psilocybin’s effects can be subjectively perceived at a dose as low as 3 mg per 70 kg body weight.
How likely is a bad trip after taking magic mushrooms?

Psilocin is the chemical primarily responsible for the hallucinogenic effects of the Psilocybe. After ingestion of the psilocybin compound alkaline phosphatases present in the body’s digestive system, kidneys, and possibly psilocybe semilanceata habitat in the blood readily cleave the phosphoryl ester bond from psilocybin, yielding the hydroxyl compound, psilocin. Hydroxylation of this compound produces the more potent hallucinogen psilocin, followed by phosphorylation yielding psilocybin. The psilocybin molecule is indirectly responsible for the hallucinogenic properties of the Psilocybe.
