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. Researchers have investigated whether psychological specialists can use psilocybin and similar hallucinogens as a treatment for depression.
One study examined the ability of psilocybin to reduce depression symptoms without dulling emotions. Results indicated that psilocybin may be successful in treating depression with psychological support. The other study assessed the relationship between psilocybin-induced hallucinations and positive therapeutic outcomes. Some people who take psilocybin may experience persistent, distressing alterations to the way they see the world.
These often take the form of a visual flashback, which is a traumatic recall of an intensely upsetting experience. People can continue to experience flashbacks anywhere from weeks to years after using the hallucinogen.
Physicians now diagnose this condition as hallucinogen-persisting perception disorder. Some individuals who use psilocybin may also experience fear, agitation, confusion, delirium , psychosis, and syndromes that resemble schizophrenia , requiring a trip to the emergency room. In most cases, a doctor will treat these effects with medication, such as benzodiazepines.
Symptoms often resolve in 6—8 hours as the effects of the psilocybin wear off. Finally, though the risk is small, some psilocybin users risk accidental poisoning from eating a poisonous mushroom by mistake. Symptoms of mushroom poisoning may include muscle spasms , confusion, and delirium. A person should visit an emergency room immediately if these symptoms occur.
In the U. They also grow in Mexico, Central and South America. The most potent species in the world is considered Psilocybe azurescens , which is found mainly in the U. Pacific Northwest. In the early s, an American banker and mushroom enthusiast named R. Gordon Wasson came across an indigenous tribe using psychoactive mushrooms when he was on vacation in Mexico, according to Drug Policy Alliance. Hoffmann isolated psilocybin from the mushroom Psilocybe mexicana in , and he developed a way to produce a synthetic version of the psychedelic compound a year later.
Since , psilocybin and psilocin have been listed by the DEA as Schedule I substances, the federal government's most restrictive category. Drugs in this category are believed to have a "high potential for abuse" as well as "no accepted medical use," according to the DEA. Psilocybin along with other drugs, such as lysergic acid diethylamide LSD and mescaline, are considered "classic psychedelics" because they can induce changes in mood, thought and perception by mimicking neurotransmitters in your brain.
Once it enters the body, psilocybin is broken down into psilocin, a substance that acts like the neurotransmitter serotonin, which regulates mood.
Psilocybin is known to activate a specific type of serotonin receptor in the brain that triggers its psychedelic effects, Johnson said. Its hallucinatory effects can cause a person to see images, hear sounds and feel sensations that seem real but aren't, according to Partnership for Drug-Free Kids.

Some people believe that magic mushrooms are safer than other drugs and produce a milder trip than other hallucinogenics.
Some people have reported much more intense and frightening hallucinations on magic mushrooms than on LSD. Many people also confuse fly agaric mushrooms with psilocybin-containing mushrooms—but they are not the same. Fly agaric mushrooms contain the psychoactive chemicals ibotenic acid and muscimol, which are known to cause twitching, drooling, sweating, dizziness, vomiting, and delirium.
Like most drugs, the more you use magic mushrooms, the more tolerance you develop. Tolerance also develops quickly with regular use. This means that you need more of the drug to achieve the same effect. Developing a tolerance can be especially risky with shrooms because consuming a large amount can result in overdose symptoms, which while not fatal, can include:. The short-term effects of magic mushrooms typically wear off in 6 to 12 hours.
The average half-life of psilocybin ranges from an hour to two, and it generally takes five to six half-lives for a substance to be eliminated from your system.

She aims to accelerate progress, with new treatment sites recently opened at Columbia University, as well as in New Orleans and the Netherlands, among others. Licensing is not the only obstacle to the drug becoming a common medicine. Taken over multiple hours in clinical settings with expert guides, psilocybin therapy does not come cheap.
Malievskaia would not comment on how much Compass would plan to charge, but says she wants to maximise how many people can access the drug. Carhart-Harris says psilocybin therapy would be significantly more expensive than antidepressants and potentially more than counselling. The scientific, legal and commercial challenges may take years to be settled.
But for many of the patients who have already been treated, and for some of the therapists guiding them, there is little doubt: it is only a matter of time before psilocybin and similar psychedelics reshape how we treat suffering — and understand our minds.
Forty-year-old operations manager Melissa Elwin is among them. After an unpleasant first treatment, in which she felt trapped, during her second psychedelic trip inside Hammersmith Hospital, she felt as though she had left her body and was seeing her problems objectively.
Psilocybin helped her confront her depression, fuelled by a difficult relationship and fraught breakup, and anxiety she had had since childhood. Her descriptions of the trip are similar to the awe and unity Hoffman at times experienced on psychedelics while testing them: he saw in them a powerful ability to put our self and troubles in perspective. I had no recollection of time and I just wanted it to last for ever.
