He Shot Mushroom Tea Into His Vein — Then Fungi Started Growing in His Blood
The moment the blood cultures lit up, the lab tech thought the machine was broken. Psilocybe cubensis — the “magic mushroom” sold in dime bags and memes — was floating, alive, in a young man’s bloodstream. Thirty years old, bipolar, and convinced he could outsmart psychiatry, he had brewed a cup of mushroom tea, loaded it into a syringe, and shot it straight into his vein. Three days later, his organs were shutting down.
What nearly killed him wasn’t the psychedelic. It was the living fungus now feeding on his blood, a rogue garden sprouting hyphae in his capillaries. The Creighton University ICU team that published the 2021 case still can’t believe the images: golden-capped mushrooms blooming where red blood cells should be.
How a kitchen experiment turned septic
The patient had bipolar I disorder. During a manic upswing he ditched lithium — “too many chemicals” — and scrolled Reddit for alternatives. Convinced psilocybin would “reset” his brain, he boiled dried psychedelic mushrooms, filtered the brown liquid through a cotton T-shirt, and shot it IV for four straight days.
By day five he was jaundiced, gasping, and vomiting blood. Paramedics found him febrile at 103 °F with a blood pressure too low to register. Cultures from every orifice grew Psilocybe cubensis plus a bonus guest, gut bacterium Brevibacillus. The combo drove septic shock: capillaries collapsed, kidneys failed, lungs filled with fluid. Eight days on a ventilator, -grade antifungals that cost more than a car, and a month in the ICU saved his life — though his kidneys still function at half capacity.
Why fungi love your bloodstream
A mushroom is not a molecule. It’s a living colony of chitin-armored cells and spores that can germinate at 98.6 °F. Swallow them and stomach acid shreds the walls before anything hits your liver. Inject them and you’ve just built a petri dish with a pulse: warm, nutrient-rich, defenseless. Within hours the spores swell, bud, and weave branching hyphae that poke through vessel walls. Your immune system screams, unleashing a cytokine storm that drowns organs in inflammation. Doctors call it fungemia; the lay translation is “blood full of mushrooms.”
Clinical psilocybin ≠ mushroom tea
The compound now tested in FDA trials is a single, synthetic crystal, pressed into a pill, swallowed under medical supervision. Trials exclude bipolar patients and use oral dosing for a reason: psychedelics can trigger mania in that group. There is no needle, no fungus, no chitin shards. Comparing the two is like confusing morphine with a poppy seed muffin.
Mania’s war on risk assessment
Bipolar disorder is cruelly deceptive: feel good for a week, decide you’re cured, stop the meds, spiral higher. In that state “pharmaceuticals = poison” logic feels rock-solid. The patient later admitted he thought psilocybin would “detox” his neurons. Mania erased the mental brakes that would have screamed don’t garden inside your own veins.
If you’re tempted to improvise
Free, confidential help is one call away:
• 988 Suicide & Crisis Lifeline — call or text 988 (U.S.)
• Crisis Text Line — text HOME to 741741 (U.S. & Canada)
• Your nearest ER — psychosis, sepsis, or suicidal thoughts are medical emergencies, not moral failures.
For evidence-based bipolar care, ask for a psychiatrist familiar with emerging psychedelic research. A handful of academic centers now run therapy trials that screen for stability and use lab-grade compounds. No kitchen syringe required.
Quick questions
Doesn’t psilocybin fight depression?
Only in tightly controlled studies using purified pills — and bipolar disorder is usually excluded because of mania risk.
Would boiling the tea have saved him?
Spores survive boiling. Even a sterile cup would still dump chitin and sugars into his bloodstream. Injection of any non-pharmaceutical liquid is Russian roulette.
Can I quit lithium to try psychedelics?
Stopping abruptly can trigger mania. Discuss supervised tapering and psychedelic trials with a psychiatrist.
What if someone has already injected mushroom tea?
Call 911. Tell the ER exactly what was used; fast antifungal and antibiotic treatment saves lives.
