Psilocybin (Magic mushrooms)
Psilocybin is a hallucinogen that occurs naturally in certain species of mushrooms. Hallucinogens alter a person's perceptions such as seeing, hearing or feeling things that are not really there. It may be sold on the street as dried whole mushrooms or as a brown powdered material. The active component is sometimes made in illegal labs and sold on the street as a white powder or tablets, or capsules.
The mushrooms are often eaten raw or cooked. They may be steeped in hot water to make a mushroom
"tea"or mixed with fruit juice to make
"fungus delight."Less often they may be sniffed, snorted, or injected.
Also Known As: magic, magic mushrooms, mushrooms, shrooms, mushies, fungus, fungus delight

How does Psilocybin Affect the Body?
After taking mushrooms, the psilocybin is absorbed into the bloodstream. The speed with which it reaches the brain varies depending on how they are taken. The effects of psilocybin are generally felt within a few minutes of drinking the tea or 30 minutes after eating mushrooms. They last for about three to six hours. Some people may experience hallucinations for up to four days.
Will Psilocybin Always Produce the Same Effects?
The effects of psilocybin are unpredictable. It is different for everyone. The way a person feels after taking psilocybin depends on many factors:
- age and weight
- mood, expectations, and environment
- whether a person has eaten recently
- the type and amount of food in a person's stomach
- medical or psychiatric conditions
- the amount of psilocybin taken (dose)
- how often and for how long psilocybin has been used
- use of other drugs, including non-prescription, prescription, and street drugs
Short-Term Effects
Psilocybin can cause a person to feel anxious and experience panic attacks. Users may experience hallucinations and a loss of touch with reality. Psilocybin can also produce distorted visual perceptions. Some people may think that they can
"see"music or
"hear"colours.
Short-term use of psilocybin can produce many other effects:
- light-headedness
- dilated pupils (causes blurred vision)
- nausea and vomiting
- dry mouth
- numbness, particularly facial numbness (paresthesia)
- exaggerated reflexes
- sweating and increased body temperature followed by chills and shivering
- muscle weakness and twitching
- increased blood pressure and heart rate
In addition, a person could potentially experience:
- paranoia
- confusion and disorientation
- severe agitation
- loss of coordination
- loss of urinary control
- convulsions
After the effects of the mushrooms wear off a user may feel very tired, depressed and lethargic for a few days.
Overdose with magic mushrooms alone has not been directly associated with death.
Long-Term Effects
The effects of long-term psilocybin use have not been studied. Some people have had prolonged psychosis that resembles paranoid schizophrenia. Psychosis is a loss of touch with reality. It is a mental disorder that affects the personality.
Can Psilocybin Harm a Developing Fetus?
The effects of psilocybin on the developing fetus are unknown.
Is Psilocybin Addictive?
There is no evidence that addiction, physical or psychological dependence develops with continued use of psilocybin. However, people can become tolerant to the effects of psilocybin with regular use. Complete tolerance, where no amount of psilocybin can produce the desired effects, can develop within several days. The user must stop using for days to regain sensitivity.
