Koa Smith says three grams of psilocybin mushrooms ended his post-concussion depression

Big-wave surfing already sounds like a sport invented by a liability lawyer having a nervous breakdown, so when Koa Smith says three grams of psilocybin mushrooms ended the numbness and depression that followed his traumatic brain injury, you can feel the internet reaching for two tabs at once. Not helped. Not inspired. Ended, at least in his telling.

That is the claim worth separating from the salt spray on The Ultimate Human. Smith tells Gary Brecka he had been run over by a jet ski, suffered a concussion, then later hit his head in the surf, blacked out underwater, heard peaceful violin music, came to, and surfaced with coral scratches across his body. After that came the less cinematic part, headaches, noise sensitivity, stress that made his head feel like an engine about to explode, and a loss of identity. Take surfing away from a surfer and you don’t just cancel a hobby. You yank out the power cord.

End your life. You could just do it. You can just end your life right now. That would solve it.

Smith is blunt about the darkness, which is part of why the story has force. He says the forest helped more than anything else at first, with a hammock, a journal, and hours away from the noise. But it didn’t fix him. A therapist offered antidepressants. Then he watched Paul Stamets talk about psilocybin in Fantastic Fungi, including the famous story about a mushroom trip and a lifelong stutter, and Smith’s brain made the jump that many desperate brains make: maybe that’s my door.

I really forgot who I was.

The miracle story, with a flashing caution sign

Smith says he and his brother went deep into an off-grid valley, stripped down in the sun, and took about three grams of mushrooms. He describes the trip like a ceremonial visitation, colors, figures, pyramids, light beings, a command to sit down, and a return to the five-year-old version of himself who was joyful, loved, and alive to the world. If this sounds like a deleted scene from Point Break written by a Jungian analyst, well, yes. But the emotional arc is clear. He wasn’t trying to party. He was trying to come back.

My heart just went boom. And that sensation went throughout my whole body and I could feel again.

Here is where the eyebrow goes up, not because Smith sounds fake, but because the phrasing gets medically slippery. He says the numbness and depression disappeared and that the experience gave him instructions that “healed my head injury.” Those instructions were sensible, even boring, which is usually where the useful stuff hides: no caffeine, no stimulants, clean diet, sleep, breath work, meditation, journaling, ocean time, forest time, and saying no to obligations he didn’t want. That sounds less like a mushroom cure for traumatic brain injury than a mushroom-assisted intervention that made him finally obey a recovery plan.

That distinction matters. Psilocybin research has become serious, especially around depression, end-of-life distress, addiction, and trauma. But a surfer’s post-concussion recovery, however vivid, is not a protocol. It is a story. A powerful one, yes. Also one that includes suicidal thoughts, a serious brain injury, and a drug experience in the wilderness. Nobody should hear this and think the move is to diagnose yourself, dose yourself, and hope the light beings have a good bedside manner.

The less sexy claim is probably the stronger one

Smith is more convincing when he talks about fear as a daily practice. Surfing, he says, does not grant permanent immunity. You don’t defeat fear once and hang the trophy over the fireplace. It shows up again tomorrow, possibly in the form of a wave that can fold you like a beach chair. His method is less macho than expected: sleep, food, meditation, and practicing tiny acts of fear, like talking to a stranger or saying the thing you’re afraid to say.

That is the part that travels beyond surfing. Smith’s big psychedelic claim will get the clips. The better takeaway is that fear management is physical before it is philosophical. If he slept badly, ate badly, drank too much caffeine, or felt anxious, he says fear swallowed him. When he took care of the basics, he could see through it. The ocean did not make him fearless. It made him honest about the bill.

He also undercuts the expected “mushroom guy” caricature. Smith says he is not eating mushrooms all the time and puts more daily faith in meditation, especially Joe Dispenza-style practice and the kind of attention training that catches the mind wandering and brings it back. Psychedelics, in his telling, are the emergency flare. Meditation is the long walk out.

But also there’s there’s you can get there through meditation but it takes a lot more self-realization, a lot of facing yourself, a lot of surrendering, letting go, dealing with with your stuff
