There’s evidence that tripping on magic mushrooms could actually free the mind.
Several studies, including two promising recent clinical trials, suggest that psilocybin, shrooms’ psychoactive ingredient, may hold the potential to help relieve severe anxiety and depression.
Still, because they’re classified as Schedule 1 — meaning they have “no accepted medical use” and are illegal — it’s been pretty tough for scientists to tease out exactly what they can and can’t do.
Here are a few of the ways we know shrooms can affect your brain and body:
According to the National Institute on Drug Abuse, magic mushrooms can lead to feelings of relaxation that are similar to the effects of low doses of marijuana.
Like other hallucinogenic drugs, such as LSD or peyote, shrooms are thought to produce most of their effects by acting on neural highways in the brain that use the neurotransmitter serotonin, according to the National Institute on Drug Abuse. More specifically, magic mushrooms affect the brain's prefrontal cortex, part of the brain that regulates abstract thinking, thought analysis, and plays a key role in mood and perception.
In people injected with 2 milligrams of the drug, researchers saw new, stronger activity across several regions of the brain that normally rarely or never engage in such 'cross-talk.' To visualise what they were seeing in the people given the drug (as opposed to those given a placebo), the researchers created the representation above.
Imperial College London neuroscientist David Nutt, who authored a 2012 study on psilocybin, also found changes in the brain activity patterns of people on the drug. While some areas became more pronounced, others were muted -- including in a region of the brain thought to play a role in maintaining our sense of self.
In depressed people, Nutt believes, the connections between brain circuits in this sense-of-self region are too strong. 'People who get into depressive thinking, their brains are overconnected,' Nutt told Psychology Today. But loosening those connections and creating new ones, the thinking goes, could provide intense relief.
For a New York University study looking at how the drug might affect cancer patients with severe anxiety, researchers observed the effects of psilocybin on volunteers who received either a dose of psilocybin in pill form or a placebo. A re-enactment of the procedure is shown in the photo above.
Nick Fernandez, a 2014 participant, says his trip took him on an emotional journey that helped him see 'a force greater than (himself),' he told Aeon Magazine. 'Something inside me snapped,' and I 'realise(d) all my anxieties, defences, and insecurities weren't something to worry about.'
NYU psychotherapist Jeffrey Guss
told the New Yorker that many partipants experienced a similar result, and added that 'We consider that to be part of the healing process.'
In many of the case reports from the NYU study, particpants reported experiencing intense anxiety and discomfort -- ranging from a few minutes to a few hours -- during their trip. It was only afterward that some said they began to feel a sense of relief; and even this experience may vary significantly for each person.
Shrooms can induce experiences that seem real but aren't. These types of out-of-body experiences, in which users might observe a version of themselves, typically begin 20 to 90 minutes after injesting the drug and can last as long as 12 hours, according to the National Institute on Drug Abuse. Experiences can vary based on how much you take, as well as by your personality, your mood and even your surroundings.
After Johns Hopkins psychologists induced out of body experiences in a small group of healthy volunteers dosed with psilocybin, the participants said they felt more open, more imaginative, and more appreciative of beauty.
When the researchers followed up with the volunteers a year later, nearly two-thirds said the experience had been one of the most important in their lives; close to half continued to score higher on a personality test of openness than they had before taking the drug.
Some users have reported lingering hallucinatory perceptions that may be linked with a rare disorder called HPPD.
Since the 1960s, there have been scattered reports of something called hallucinogen persisting perception disorder -- when hallucinations continue long after someone's taken a hallucinogenic drug, typically LSD. (There are also some anecdotal reports of it from people who've used shrooms).
Scientists still have yet to come up with a strict definition of HPPD, but Dr. John Halpern, an assistant professor of psychiatry at Harvard Medical School and lead author of the most recent review of HPPD, told the New Yorker that
'it seems inescapable,' based on twenty related studies dating back to 1966, 'that at least some individuals who have used LSD, in particular, experience persistent perceptual abnormalities reminiscent of acute intoxication, not better attributable to another medical or psychiatric condition.'
