The quantity of the drug a person consumes, their past experiences, and their expectations of how the experience will take shape can all impact the effects of psilocybin. The hallucinogenic effects of psilocybin usually occur within 30 minutes after a person ingests it and last 4—6 hours. In some individuals, changes in sensory perception and thought patterns can last for several days. The amount of psilocybin in dried mushrooms is about 10 times higher than that found in their fresh counterparts.
Mushrooms containing psilocybin are small and usually brown or tan. In the wild, people often mistake mushrooms containing psilocybin for any number of other mushrooms that are poisonous. People usually consume psilocybin as a brewed tea or prepare it with a food item to mask its bitter taste. Manufacturers also crush dried mushrooms into a powder and prepare them in capsule form. Some people who consume these mushrooms cover them with chocolate. The ritual use of psilocybin for mystical or spiritual purposes dates back to pre-Columbian Mesoamerican societies and continues to this day.
Psilocybin is often used recreationally at dance clubs or by people seeking a transcendent spiritual experience. In medical settings, doctors have tested psilocybin for treating cluster headaches , depression , end stage cancer anxiety, and other forms of anxiety.
The effects of psilocybin are generally similar to those of LSD. They include altered perception of time and space and intense changes in mood and feeling. If the user has a mental health condition or feels anxious about using the hallucinogen, they face a higher risk of having a bad experience. Psychological distress is the adverse event most often reported after recreational use of psilocybin. This distress can take the form of extreme anxiety or short-term psychosis.
In contrast to LSD, psilocin does not have an effect on the dopamine receptor. Tryptamines and phenethylamine hallucinogens both have a relatively high affinity for serotonin 5-HT 2 receptors, but they differ in their affinity for other subtypes of serotonin receptors. The correlation between the relative affinity of hallucinogens for 5-HT 2 -receptors and their potency as hallucinogens in human beings suggest that an important component of the mechanism of action of these substances is through stimulation of brain 5-HT 2 -receptors.
A primary role for the 5-HT 2 -receptor in the mechanism of hallucinations is further suggested by the observation that antagonists of the 5-HT 2 -receptor are effective in blocking the behavioural and electrophysiological effects of hallucinogenic drugs in animals and in man.
Although 5HT 2 -receptors are certainly involved, at present, it is not possible to attribute the psychedelic effects to any single 5-HT receptor subtype. Behavioural effects are dependent on dose and the individual reaction and sensitivity to psilocybin, previous experiences and the setting. The major effects are related to the central nervous system, but there are also some sympathomimetic effects.
The subjective effects, however, may vary greatly between individuals and from one episode of use to the next within the same person. The effects range from mild feelings of relaxation, giddiness, euphoria, visual enhancement seeing colours brighter , visual disturbances moving surfaces, waves , to delusions, altered perception of real events, images and faces, or real hallucinations. The sensory distortions may be coupled with restlessness, incoordination, feelings of anxiety, impaired judgement of time or distance, sense of unreality or even depersonalisation.
These effects may be termed 'bad trips' by users and can also involve panic reactions and psychosis-like states. In general, the physiological effects are not significant, but may include dizziness, nausea, weakness, muscle aching, shivering, abdominal pain, dilation of pupils mydriasis , mild-to-moderate increase in heart rate tachycardia and breathing tachypnea and elevation of blood pressure. Generally, body temperature remains normal.
However, pronounced physical symptoms such as severe stomach pain, persistent vomiting, diarrhoea etc. Both psilocybin and psilocin can be produced synthetically, but this form of the drug is not often found. Users purchase hallucinogenic mushrooms and by-products from smartshops and on the Internet, or pick them wild.
The cubensis varieties are cultivated specifically mostly in the Netherlands. The types of magic mushrooms most commonly sold by smartshops in the Netherlands are the Psilocybe cubensis varieties. Online shops sell a variety of hallucinogenic mushroom products ranging from fresh mushrooms to spore prints, spawnbags and growkits. The majority of online shops offer international shipping, although most sites do not ship to countries where sales are prohibited.
Recreational doses range from 1—5 grams of dry mushrooms depending on the species and individual strength of the specimens. Dosages for fresh mushrooms will be approximately 10 times higher 10—50 grams.
The material may be eaten raw, boiled in water to make tea, or cooked with other foods to cover its bitter flavour. After ingestion, the psilocybin is enzymatically converted to psilocin. Absorbed from the gastro-intestinal tract, hallucinogenic effects usually occur within 30 minutes of ingestion with a duration of effect of 4—6 hours.
Consider a study of 75 subjects, published in the Journal of Psychopharmacology last October. The study concluded that psilocybin leads to mystical experiences that can have long-term psychological benefits in conjunction with meditation training.
The greater the drug dosage, the more potent the positive psychological effect was six months later. Meanwhile, in July, psychologist Richard Williams of John Hopkins University revealed an experiment involving clergy and psilocybin.
The study will last a year, so no results are out yet. But Williams told The Guardian in July that so far, the clerics report feeling simultaneously more in touch with their own faith and greater appreciation for alternate paths.
To understand how mushrooms can change our worldviews, we must first explore how brains shape our sense of self. Yet when you are unconscious, you continue to exist without perceiving your own presence. You cease to participate in reality but continue to live. When roused back into consciousness, you lack a narrative to explain the time away. In this agreed-upon reality, we are each separate individuals, whose stories begin with our births and end with our deaths.
But there are other ways to experience reality, which you may have already glimpsed, even if only fleetingly. Sometimes our consciousness shifts. The boundaries of the self seem to become less rigid and we commune with another person or thing, as can happen during drug-induced epiphanies, sure—but can also happen when people fall in love, meditate, go out in nature, or experience a great meeting of minds.
He and others—mystics, monks , poets pdf , and philosophers from numerous traditions—argue that people are sad and hostile because we live with a false sense of separation from one another and the rest of the world.
