Psychedelics & Brain Injuries
For most Americans, the word psychedelics still conjures a 1960s cultural reference — counterculture, recreational drug use, something dangerous and fringe. That association didn't happen by accident. The criminalization of psychedelics in the United States was less about public safety than about politics. Nixon's War on Drugs deliberately targeted the communities and movements his administration most wanted to suppress — the antiwar left, Black Americans, and the counterculture. Psychedelics got swept up in that agenda. The science didn't drive the policy. The politics did.
It worked. Decades of research were shut down. Stigma calcified into law. And a generation of people who might have benefited from this medicine were left without access to it — including athletes whose brains were quietly breaking down long after the final whistle.
Now the science is back — and so is the politics. An April 2026 executive order is pushing to bring psychedelic medicine under the control of the pharmaceutical and insurance model. The same system that spent fifty years blocking this research now wants to own it. Natural medicines that have existed for thousands of years are being directed toward a framework built around patents, profits, and insurance reimbursement. Not healing. Revenue.
Colorado saw this coming. The Natural Medicine Health Act was built to keep psychedelic medicine accessible, legal, and outside the grip of that system. It is not a loophole. It is a deliberate choice to put healing ahead of profit.
There is also something important that gets lost in the medicalization conversation. Psychedelic healing is not a pill you swallow in a doctor's office. Set, setting, and the skill of the facilitator are not peripheral details — they are the work. The environment matters. The relationship matters. The intention matters. That is not mysticism. That is the science too.
This page explains how psychedelic medicine works — in plain language, grounded in science — and why it matters specifically for athletes living with brain injuries.
What brain injury actually does.
CTE and traumatic brain injury don't just affect memory and cognition. They trigger a cascade of damage inside the brain: chronic neuroinflammation, the death of neurons, disruption to the gut-brain axis, and the deterioration of the prefrontal cortex — the region responsible for emotional regulation, decision-making, and impulse control. The result is the full range of symptoms former athletes know well: rage, depression, anxiety, cognitive decline, and behavioral changes that strain every relationship in their lives.
Conventional medicine can manage some symptoms at the margins. It has not been able to reverse the underlying damage — or address the trauma that so often compounds it.
What psilocybin does.
Psilocybin — the active compound in psychedelic mushrooms — works on the brain in ways that are fundamentally different from pharmaceuticals. Here is what the research shows.
It reduces neuroinflammation.
Chronic inflammation is one of the central mechanisms of decline in CTE and traumatic brain injury. The brain gets stuck in a state of ongoing damage — and conventional medicine has no reliable way to stop it. Psilocybin binds to serotonin receptors in the brain, triggering a reduction in pro-inflammatory signaling while increasing anti-inflammatory activity. The result is measurable: less ongoing deterioration, and a brain that can begin to recover rather than just survive.
It rebuilds neural connections.
Brain injury breaks down the connections between neurons — the pathways responsible for memory, focus, emotional regulation, and decision-making. Psilocybin activates neuroplasticity, triggering the growth of new dendritic spines and elevating levels of BDNF. In plain terms: it helps a damaged brain rewire itself in ways that pharmaceuticals cannot replicate.
It processes trauma.
Brain injury and unresolved trauma rarely travel alone. Psilocybin temporarily reduces activity in the amygdala — the brain's threat-detection center — allowing difficult memories and emotions to surface without triggering the fight-or-flight response. The brain can revisit what happened from a distance, process it without the grip of fear and shame, and file it where it belongs: in the past.
It breaks the loop.
Depression and anxiety in brain injury are driven in part by the default mode network — a set of brain regions that activates during rumination and negative thought loops. Psilocybin temporarily disrupts this network, quieting the loop and creating a window of heightened openness and neuroplasticity. This is why the effects often extend well beyond the session itself.
Where the research stands.
This is not fringe science. Psilocybin has received FDA Breakthrough Therapy designation for treatment-resistant depression. Peer-reviewed research from institutions including Johns Hopkins, Monash University, and King's College London has documented its effects on neuroplasticity, neuroinflammation, trauma processing, and brain connectivity. Studies specifically examining psilocybin's application to traumatic brain injury are growing — and the early findings are significant.
The research is not yet complete. No responsible practitioner will tell you otherwise. But the evidence base is substantial and it is growing. For former athletes living with brain injuries, it represents a legitimate and meaningful path forward.
