Psilocybin is a hallucinogenic chemical found in certain mushrooms, commonly known as magic mushrooms. It is often used as a recreational drug and can cause a range of effects, from euphoria to hallucinations. While it has been deemed a Schedule I substance by the Drug Enforcement Administration (DEA), indicating a high potential for abuse and no legitimate medical purpose, recent studies have suggested that psilocybin may have therapeutic potential, particularly in treating depression. Despite its classification, psilocybin has low toxicity, with a low risk of inducing life-threatening events such as breathing or heart problems. However, adverse effects such as anxiety, paranoia, and psychosis may occur, and frequent, repeated use may lead to cardiac issues. Poisoning from hallucinogenic mushrooms is possible, often due to misidentification of toxic mushroom species, and can result in serious organ dysfunction or fatalities.
| Characteristics | Values |
|---|---|
| Toxicity | Psilocybin has low toxicity, meaning there is a low risk of inducing life-threatening events like breathing or heart problems. However, psilocybin is a hallucinogenic chemical found in certain mushrooms, known as "magic mushrooms", and can be toxic in high doses or if consumed by children. |
| Therapeutic Index | The Registry of Toxic Effects of Chemical Substances assigns psilocybin a relatively high therapeutic index of 641, indicating a better safety profile compared to other substances like aspirin and nicotine. |
| Lethal Dose | The lethal dose of psilocybin in mice is 285 mg/kg, in rats is 280 mg/kg, and in rabbits is 12.5 mg/kg. The human lethal dose has been estimated to be 2,000 to 6,000 mg, which is much higher than the effective dose of 6 mg and the typical recreational dose of 10 to 30 mg. |
| Symptoms of Toxicity | Symptoms of psilocybin toxicity include hypertension, tachycardia, visual problems, nausea, anxiety, asthenia, vertigo, mydriasis, motor incoordination, disorientation, and hallucinations. |
| Treatment | Treatment for psilocybin toxicity involves keeping the patient in a quiet room and providing sedation with benzodiazepines, and if needed, adding antipsychotic drugs. |
| Poisoning | Psilocybin mushrooms can lead to poisoning if misidentified as another variety of mushroom. Mushroom poisoning is a significant global health issue, with thousands of reported cases and deaths worldwide. |
| Health Risks | Frequent, repeated use of psilocybin may lead to cardiac fibrosis and valvulopathy. Other potential adverse effects include nausea, vomiting, muscle weakness, panic reactions, and psychotic episodes. Hospitalizations and overdoses are rare, and overdoses are typically mild and self-limiting. |

Psilocybin has low toxicity and a low risk of causing life-threatening events
Psilocybin is a hallucinogenic chemical found in certain mushrooms, commonly known as magic mushrooms. It is a Schedule I substance, meaning that the Drug Enforcement Administration (DEA) believes it has a high potential for abuse and serves no legitimate medical purpose. However, psilocybin has low toxicity, indicating a low risk of causing life-threatening events.
The toxicity symptoms of psilocybin develop within 30 minutes of ingestion and can include hypertension, tachycardia, visual problems, nausea, anxiety, asthenia, vertigo, mydriasis, motor incoordination, and disorientation. These symptoms typically resolve within 4 to 12 hours without the need for hospitalization. Psilocybin's sympathomimetic or cardiovascular effects, such as increased heart rate and blood pressure, are usually mild. On average, peak heart rate increases by 5 bpm, peak systolic blood pressure by 10 to 15 mm Hg, and peak diastolic blood pressure by 5 to 10 mm Hg.
While psilocybin has low toxicity, it can lead to poisoning if it is incorrectly identified and consumed as a different variety of poisonous mushroom. Mushroom poisoning is a significant global health concern, and cases of serious human poisoning occur annually due to the improper identification of toxic mushroom species. Psilocybin mushrooms can be distinguished by their appearance, such as the "liberty cap" Psilocybe semilanceata, which is the most popular in this group.
Additionally, the lethal dose of psilocybin in humans has been estimated to be 2,000 to 6,000 mg, which is significantly higher than the effective dose of 6 mg and the typical recreational dose of 10 to 30 mg. This further supports the notion that psilocybin has low toxicity and a low risk of causing life-threatening events, even at higher doses. However, it is important to note that the effects of psilocybin vary between individuals, and factors such as mental state, personality, and environment can influence the overall experience.
In conclusion, while psilocybin is considered a hallucinogenic substance with potential risks, it exhibits low toxicity and a low tendency to induce life-threatening events. The risks associated with psilocybin are primarily related to improper identification of mushroom species and individual factors that influence the psychological and physiological effects of the substance.

Psilocybin is a hallucinogenic chemical found in 'magic mushrooms'
Psilocybin is a hallucinogenic chemical found in certain mushrooms known as magic mushrooms. Eating mushrooms that contain psilocybin can have a variety of effects, ranging from euphoria to hallucinations. Some people use psilocybin as a recreational drug, but it is also being studied for potential therapeutic uses. Psilocybin works by binding to and activating serotonin receptors in parts of the brain that affect mood, cognition, and perception.
Psilocybin is considered to have low toxicity, with a relatively high therapeutic index of 641, indicating a good safety profile. Research suggests that the risks associated with psilocybin are relatively mild and self-limiting, and hospitalizations are rare. However, there are potential risks associated with its use, including increased heart rate and blood pressure, nausea, vomiting, and psychological consequences such as anxiety, panic, and hallucinations. Psilocybin abuse can also lead to poisoning if poisonous mushrooms are incorrectly identified as psilocybin-containing mushrooms.
The effects of psilocybin can vary between individuals, depending on factors such as dosage, mental state, personality, and environment. Higher doses may increase the risk of negative experiences, and pre-existing mental health conditions may also be a factor. Psilocybin has been shown to have the potential to induce mystical-type experiences of substantial and sustained personal meaning and spiritual significance. However, not everyone in the medical community agrees with this interpretation, with some arguing that it produces a "lower consciousness" known as toxic delirium.
Psilocybin has been used in indigenous New World cultures for religious, divinatory, or spiritual contexts for millennia. It is also being explored in Western clinical practice through group therapies, with potential for growth provided that evidence supports its safety and efficacy. While psilocybin is currently classified as a Schedule I substance by the Drug Enforcement Administration (DEA), indicating a high potential for abuse and no legitimate medical purpose, research is ongoing and may lead to a reevaluation of its status.

Psilocybin has therapeutic potential in treating depression
Psilocybin is a hallucinogenic chemical found in certain mushrooms, commonly known as magic mushrooms. It has been used in indigenous New World cultures for religious, divinatory, or spiritual contexts for millennia. Psilocybin works by binding to and activating serotonin receptors in parts of the brain, such as the prefrontal cortex and amygdala, which affect mood, cognition, and perception.
Psilocybin has the potential to be used as an antidepressant. Preliminary studies involving patients with life-threatening cancer have suggested therapeutic potential for this agent. In a phase 2 double-blind trial, adults with treatment-resistant depression were randomly assigned to receive a single dose of a proprietary, synthetic formulation of psilocybin at a dose of 25 mg, 10 mg, or 1 mg (control), along with psychological support. The results showed that psilocybin produced significant and immediate effects, with a long duration, suggesting that it may be a uniquely useful new treatment for depression.
Another study conducted by Johns Hopkins University School of Medicine showed that psilocybin treatment for major depression was effective for up to a year for most patients. The researchers recruited 27 participants with a long-term history of depression and provided them with preparatory meetings with treatment facilitators before administering the psilocybin doses. The results showed stable rates of response to the treatment and remission of symptoms throughout the follow-up period, with 75% response and 58% remission at 12 months.
While psilocybin has shown potential in treating depression, it is important to note that it can also cause adverse effects. Psilocybin can cause mystical-type experiences that may lead to disturbing hallucinations, anxiety, and panic. It can also cause temporary increases in blood pressure, which can be a risk factor for users with preexisting hypertension. Additionally, there is a potential risk of cardiac fibrosis and valvulopathy with frequent repeated use of psilocybin. Therefore, it is crucial that the use of psilocybin for treating depression is carefully controlled and monitored by trained clinicians and therapists.

Psilocybin can cause mystical experiences of substantial personal meaning
Psilocybin is a hallucinogenic chemical found in certain mushrooms called magic mushrooms. It has been used for centuries for religious purposes, but its acute and persisting effects are not yet fully understood. Psilocybin is listed as a Schedule I substance by the Drug Enforcement Administration (DEA), which means it is considered to have a high potential for abuse and no legitimate medical purpose. However, psilocybin has shown promise in helping to treat or manage certain conditions, such as depression.
Psilocybin has low toxicity, meaning there is a low risk of inducing life-threatening events like breathing or heart problems. Research has shown that psilocybin can cause mystical-type experiences of substantial and sustained personal meaning and spiritual significance. These experiences have been reported to have positive changes in attitudes and behavior consistent with changes rated by community observers. Volunteers in studies have rated the psilocybin experience as having substantial personal meaning and spiritual significance, with many attributing sustained positive changes in their lives to the experience.
A study by Griffiths et al. (2006) found that 58% and 67% of volunteers, respectively, rated the psilocybin experience as being among the five most personally meaningful and spiritually significant experiences of their lives. Additionally, 64% of the volunteers indicated that the experience increased their sense of well-being or life satisfaction. Another study by Pahnke (1963) analysed the relationship between psychedelic drugs and mystical consciousness, exploring the link between LSD and religious experience.
The effects of psilocybin vary between people, and factors such as mental state, personality, and environment may affect an individual's response. Psilocybin may cause visual or auditory hallucinations and distort how people perceive their environment. It can also produce feelings of euphoria and sensory distortion. Psilocybin's sympathomimetic or cardiovascular effects, including increased heart rate and blood pressure, are usually mild. However, temporary increases in blood pressure can be a risk factor for users with pre-existing hypertension.
While psilocybin has the potential to induce mystical experiences with substantial personal meaning, it is important to approach it with caution. Psilocybin mushrooms can be dangerous if consumed without proper knowledge, as they resemble some highly toxic mushrooms. Additionally, there are potential risks associated with hallucinogen exposure, including panic or fear reactions and the precipitation or exacerbation of psychiatric conditions.
