It sounds like a bad urban legend. You’ve probably heard it whispered at parties or seen a sensationalist headline scrolling through your feed: a man on mushrooms cuts off penis. It’s the kind of story that stops you mid-breath because it's so visceral, so irreversible, and frankly, so terrifying. People usually dismiss it as "reefer madness" style propaganda or a freak accident involving someone who was already "crazy."
But it actually happened.
In late 2023, a case report published in the Journal of Medical Case Reports detailed a 37-year-old man in Austria who, while alone in a vacation home, consumed a large quantity of psilocybin mushrooms. Shortly after, in the throes of a massive psychotic episode, he used a kitchen knife to perform a crude self-amputation. He didn’t just nick himself. He severed the organ into several pieces.
He didn't seek help immediately. For five hours, he sat in a state of profound disorientation, likely unable to process the physical reality of what he had done. Eventually, he sought help in a nearby village, leading to a complex surgical intervention where doctors attempted to reattach the pieces.
The Reality of Psilocybin-Induced Psychosis
Most people who use psychedelics talk about "opening their third eye" or seeing pretty colors. They talk about ego death. They don't talk about the dark side.
When we talk about a man on mushrooms cuts off penis, we aren't talking about a standard "bad trip" where someone gets a bit anxious because the walls are melting. We are talking about a total break from reality. This is clinically known as substance-induced psychosis.
Psilocybin works by binding to serotonin 2A receptors in the brain. Usually, this just causes some visual distortions and a feeling of interconnectedness. But in high doses, or in people with a specific genetic vulnerability, the "filter" of the brain completely collapses. The prefrontal cortex—the part of your brain that says "Hey, don't use that knife on yourself"—basically goes offline.
The Austrian case wasn't just about the drugs, though. The man had a history of depression and was struggling with alcohol use. This matters. Context is everything in toxicology. When you mix a vulnerable psyche with a massive dose of psilocybin, the internal narrative can turn violent. He wasn't trying to hurt himself because he hated his body; he was reacting to a perceived "religious" or "cosmic" necessity that only made sense in his fractured state of mind.
Why Self-Mutilation Happens During Trips
It’s called Klingsor syndrome. That’s the medical term for non-suicidal self-amputation of the genitalia. It is incredibly rare, but when it happens, it is almost always tied to severe mental illness like schizophrenia or, in this case, acute drug-induced psychosis.
Why the penis?
Psychiatrists often point to the symbolic weight of the organ. In a psychotic state, the mind searches for symbols. If a person is experiencing intense guilt, religious mania, or a feeling of "sin," they may target the body part they associate with those feelings. During the incident where the man on mushrooms cuts off penis, he reportedly felt a need to "cleanse" or "sacrifice."
It’s a glitch in the software. A horrific, life-altering glitch.
- The brain loses its ability to distinguish between "self" and "other."
- Pain signals are often misinterpreted or completely ignored due to the flood of neurochemicals.
- The person may believe they are performing a ritual that is necessary to save the world or achieve a higher state of being.
Comparing the Rare and the Common
We have to be honest here: millions of people use psilocybin every year without picking up a knife. Microdosing is literally a corporate trend in Silicon Valley. So, is the drug dangerous?

It’s a matter of dosage and "set and setting."
The man in the Austria case took a lot. We aren't talking about a recreational nibble. He consumed a quantity that most experienced psychonauts would consider reckless. When you push the brain that far, you’re gambling with your biology.
Most mushroom-related injuries are much more mundane. People fall down. They walk into traffic because they think they can fly (another rare but real phenomenon). They have panic attacks that land them in the ER. The man on mushrooms cuts off penis headline is the absolute extreme—the 0.001% event. But the fact that it's possible reminds us that these substances aren't toys. They are powerful tools that can break if handled improperly.
Medical Intervention and Reattachment
The medical details of the Austrian case are actually a marvel of modern surgery. Because the man had put the severed parts in a jar with snow (which he luckily found outside), the tissue was preserved just enough.
Surgeons at the hospital had to perform a microscopic reattachment. This involves sewing together tiny blood vessels and nerves thinner than a human hair. Because the amputation was "shredded" rather than a clean cut, the success was limited.
He survived. He can urinate. But the sexual function is, as you can imagine, severely compromised. This isn't a story with a "happily ever after" ending. It’s a story of permanent disability caused by a single afternoon of poor choices and bad chemistry.
What Most People Get Wrong About Mushroom Safety
The "mushrooms are natural, so they are safe" argument is a dangerous fallacy. Arsenic is natural. Hemlock is natural. Nature doesn't care about your well-being.
The biggest misconception is that psilocybin is a "soft" drug. While it's not physically addictive like heroin, its impact on the mind is arguably much more profound. If you have a family history of bipolar disorder or schizophrenia, taking mushrooms is like throwing a lit match into a room full of gasoline.
Another mistake? Doing it alone.
If that man had a "trip sitter"—a sober person there to keep him grounded—the man on mushrooms cuts off penis news story wouldn't exist. Someone would have taken the knife away. Someone would have called 911 long before things turned surgical.
Moving Toward Safer Use and Harm Reduction
If we want to prevent these horrific incidents, we have to move past the "just say no" rhetoric and into "how to stay safe" territory. The legalization movement is gaining steam in places like Oregon and Colorado, which means more people will have access.
Education is the only real shield.
First, knowing your dose is vital. You don't just "eat a handful." You weigh it. You understand the potency of the specific strain. Second, you never, ever trip alone if you are doing a high dose. This is non-negotiable.
Third, the "set and setting" rule isn't just hippie talk. It's safety protocol. If you are in a bad headspace—if you are depressed, drunk, or in an unstable environment—the drug will amplify that instability. The Austrian man was alone, drinking, and already in a dark place. He created the perfect storm for a psychotic break.
Actionable Steps for Safety and Awareness
If you or someone you know is considering using psilocybin for therapeutic or recreational reasons, you need a plan that prioritizes safety over "enlightenment."
Screen for Mental Health History: If you have ever experienced hallucinations or have a family history of psychotic disorders, stay away. The risk of a permanent break or a violent episode like the man on mushrooms cuts off penis case is significantly higher for you.
The "Sober Third" Rule: Always have a sober person present who is experienced in handling high-anxiety situations. Their job is to keep the environment safe and intervene if reality starts to slip.
Secure the Environment: This sounds paranoid until it isn't. If you are doing a high-dose trip, hide the kitchen knives. Lock the balcony. It sounds extreme, but when your brain decides the floor is lava or your arm is a snake, you’ll be glad you did.
Integration is Key: If a trip goes bad, don't just try to sleep it off and forget it. Talk to a therapist who understands psychedelics. These experiences can leave lasting trauma if not processed correctly.

Test Your Substance: While rare, some "magic mushrooms" bought on the street are actually store-bought mushrooms sprayed with research chemicals (synthetic cannabinoids or bath salts). These are much more likely to cause violent psychosis than actual psilocybin.
The case of the Austrian man is a sobering reminder of the power of the human mind and the chemicals that can unlock its darkest corners. It shouldn't necessarily be used to demonize a substance that helps many with PTSD and end-of-life anxiety, but it must be used as a boundary. Respect the drug, or pay a price that no one should ever have to pay.
