Microdosing psilocybin in Colorado — science, personal use, licensed facilitation, and the wisdom of the Earth. What the research actually shows, what Colorado law permits, and what this work is not.
Reverence for the medicine. Responsibility for the experience.

Where a responsible conversation begins
There is a difference between believing nature has something to teach us and pretending we already understand everything it is teaching. That difference matters.
Psilocybin has moved rapidly from cultural taboo into mainstream conversation. Executives talk about microdosing. Researchers study psychedelic compounds for depression and other serious conditions. Colorado has built the country's most ambitious state framework around natural medicine. And yet there is still a great deal we do not know. That may be exactly where a responsible conversation should begin.
Respect for the science. Respect for the law. Respect for Indigenous and ancestral traditions that worked with psychoactive fungi long before modern medicine took an interest in them. And respect for the simple reality that something being found in nature does not automatically make it harmless, or make every claim made about it true.
At Dream Bigley, the deeper philosophy is not that mushrooms contain a shortcut to becoming someone new. It is that sometimes changing the conditions around us can help us see differently what has been within us all along.
Section One
In contemporary psychedelic culture, microdosing generally refers to taking a very small amount of a psychedelic substance with the intention of producing subtle effects rather than a conventional psychedelic experience.
There is no single universally accepted clinical definition of a psilocybin microdose, and research protocols vary considerably. That matters because the word microdose can make something sound standardized when it isn't.
Researchers commonly describe microdosing as repeated exposure to low or very low doses intended to avoid the pronounced perceptual changes associated with larger psychedelic doses. The National Center for Complementary and Integrative Health notes that people commonly report using microdoses in hopes of improving mood, stress, productivity, focus, or pain — but also states clearly that it is not yet known whether microdosing psilocybin is safe or effective.
Microdosing is better understood as an emerging practice under active scientific investigation, not an established medical treatment. That distinction is foundational to everything that follows.
Section Two
Johnny Bigley's relationship with psilocybin did not begin as a productivity experiment. It began in pain.
In 2023, The Denver Post told part of Johnny's story in an article titled "These Coloradans sought out psilocybin-assisted therapy before it was legal. Here's why." The newspaper reported that in 2021 Johnny sat in a Denver apartment preparing for a facilitated psilocybin experience after carrying decades of unresolved childhood trauma and grief surrounding the death of his father when Johnny was 13.
He had spent years accomplishing things externally while struggling internally. The experience described by the Denver Post was emotional and intense. Johnny described moving through fear, grief, forgiveness and tears, and eventually being able to speak aloud things he had held privately for decades. For Johnny, that experience became part of a much larger personal transformation.
But an important distinction needs to be made. Johnny's experience was not microdosing. It was a substantially larger guided psychedelic experience. His story should not be used as scientific evidence that microdosing produces the same effects. It demonstrates something different: what can happen when a person who has spent decades avoiding parts of himself finally becomes willing to look inward — and that the substance itself was not the end of the story. There was still a marriage. A family. A business. Patterns. Choices. Responsibility. And life after the experience.
Section Three
One of the most dangerous narratives surrounding psychedelics is the idea of the miracle experience. Take something. Have a revelation. Become healed.
Human beings rarely work that way. A person may have an extraordinary realization and still return home to the same marriage, the same employees, the same triggers, the same body, the same habits, the same unfinished conversations. An experience may change what someone can see. It does not automatically change what they do with it.
This is one reason Colorado's regulated model doesn't treat natural medicine as simply a product someone purchases and walks away with. The regulatory framework includes preparation, informed consent, screening, administration and integration as distinct pieces of natural medicine services. Licensed facilitators also carry obligations involving participant safety, documentation, transportation planning, risks, benefits, boundaries and other safeguards. Context matters.
Section Four
The phrase "plant medicine" is widely used culturally. But accuracy matters here too. Psilocybin mushrooms are not plants. They are fungi.
Psilocybin is a naturally occurring compound produced by numerous species of mushrooms. Research into the evolutionary ecology of psilocybin suggests that the compound existed as part of fungal biology long before humans ever encountered it, although scientists still do not know its precise ecological role. That fact actually makes the story more extraordinary, not less.
Historical and ethnomycological research documents the ceremonial and healing use of psilocybin-containing mushrooms among Indigenous peoples of Mesoamerica. The Mexica and Aztec term teonanácatl is commonly translated as "flesh of the gods," and historical accounts describe mushrooms being incorporated into religious and healing practices. Modern psychedelic culture should approach that history with humility. It would be inaccurate to claim that ancient cultures practiced today's Western concept of microdosing. It would also be disrespectful to flatten sophisticated Indigenous traditions into an inspirational slogan.
The Western scientific model asks: what does this molecule do? Traditional systems may also ask: what is our relationship with it? Those questions don't have to compete. They can keep each other honest.
Section Five
Natural does not mean harmless. Nature gives us nourishment. Nature also gives us poison. The same Earth produces medicines, toxins, allergens, venom and organisms capable of killing us. Respect for nature therefore shouldn't produce recklessness. It should produce humility.
Psilocybin can produce powerful changes in perception, emotion and cognition. Reported adverse effects can include anxiety, confusion, nausea, headaches, increased blood pressure or heart rate, paranoia, panic and other difficult psychological experiences. Certain psychiatric conditions can significantly increase risk, and researchers routinely use careful screening criteria in clinical studies. Even at lower doses, NCCIH notes reports of insomnia, increased anxiety, poor mood, physical discomfort, problems with concentration and other unwanted effects.
Reverence should never mean pretending risk doesn't exist. Reverence means taking responsibility seriously.
Section Six
There are really two bodies of evidence: what people report, and what researchers have been able to demonstrate under controlled conditions. They do not perfectly match.
In a large 2022 observational study, researchers followed 953 people who were microdosing psilocybin and 180 people who were not. The microdosing group showed small-to-medium improvements in measures of mood and mental health over approximately one month. That is interesting. But observational research cannot establish that microdosing itself caused those changes — someone who begins microdosing may simultaneously begin meditating, exercising, drinking less, journaling, spending more time outside, entering therapy, or joining a community. All of those things matter.
Controlled research has therefore produced a more cautious picture. A 2022 double-blind, placebo-controlled study found noticeable subjective and brain-activity effects at low doses but did not find evidence supporting improvements in well-being, creativity or cognitive function; the researchers concluded that expectation appeared to explain at least some commonly reported benefits. But even the placebo question isn't completely settled: a 2024 review of 19 placebo-controlled studies concluded that low-dose psychedelics appear capable of producing measurable changes in physiology, neurobiology, subjective experience and some aspects of cognition, while arguing the research was still too limited to call microdosing simply a placebo phenomenon. And a 2026 systematic review and meta-analysis covering 24 studies and 3,681 participants found subjective and neurophysiological effects from microdosing but minimal consistent benefit for cognition, creativity or sustained mood.
Something is happening. We are still determining exactly what, for whom, under what circumstances, and how much of the reported benefit comes from the substance itself versus expectation, context and accompanying behavioral change. That uncertainty isn't a weakness. That's what honest science looks like.
Perhaps the most useful question isn't "does this mushroom change my life?" Perhaps it is "what am I doing differently with my life because I have decided to pay attention?" That is where natural medicine can become a teacher rather than a product.
Section Seven
Colorado has created something unusual in American law. There are effectively two distinct pathways to understand: personal use and regulated natural medicine services. They should not be confused.
Colorado voters approved Proposition 122, the Natural Medicine Health Act, in 2022. The General Assembly subsequently refined the law through SB23-290 and later legislation. For adults 21 and older, Colorado law generally protects personal possession, consumption, cultivation and noncommercial sharing of qualifying natural medicine within defined limits. Colorado's statutory definition of personal use also recognizes sharing with another adult in contexts that can include counseling, spiritual guidance, beneficial community-based use and healing, supported use, or related services.
But the word personal is important. Selling natural medicine for remuneration outside the regulated framework remains prohibited. Cultivation must occur on private property, with restrictions intended to prevent access by people under 21. Public consumption remains unlawful. In other words, Colorado changed criminal law around personal use. It did not turn psilocybin mushrooms into ordinary retail merchandise.
Separate from personal use, Colorado created a regulated system for natural medicine services. The Colorado Department of Regulatory Agencies oversees professional facilitator licensing, while the Department of Revenue regulates natural-medicine businesses and the regulated supply chain.
Licensed facilitation is much more structured than simply sitting with someone while they take mushrooms. Colorado's rules address screening, informed consent, preparation, participant goals, risk assessment, safety and support plans, transportation planning, administration, professional boundaries, documentation, and integration. The rules also require licensed facilitators to represent their credentials accurately and disclose the licenses they hold.
Colorado enacted HB26-1325 in 2026, with the relevant session law effective August 12, 2026. Among other changes, the law prohibits advertising natural medicine or natural-medicine products and restricts advertising of bona fide harm-reduction or support services offered for remuneration in the personal-use framework. It also prohibits using those services as a mechanism for conducting natural-medicine sales.
Section Eight
Perhaps the most responsible way to understand microdosing is to be equally clear about what it is not.
Section Nine
The future of natural medicine should probably not be built by people promising miracles. It should be built by people willing to say what they know, and what they do not:
That kind of honesty creates a safer container than certainty ever could. A responsible approach values preparation before experience and integration afterward. It respects consent. It screens rather than assumes. It recognizes when another professional needs to become involved. It does not pressure. It does not promise a cure. It does not sell transformation by the milligram. And it never confuses surrender with giving away personal agency.
At Dream Bigley, nature becomes more than scenery around the work. It becomes metaphor — five teachers from one source: the eagle teaches perspective, the jaguar asks us to enter what we fear, the snake shows that life grows by shedding, the elephant teaches grounded strength, and the hummingbird reminds us that life happens in the moment we inhabit. Different lessons. One Earth.
The goal is never worship of the substance. The goal is relationship with the lesson.
Section Ten
No. That isn't the question. Microdosing will not be right for everyone. Some people will decide it isn't right for them at all. Some will find that meditation, therapy, exercise, community, time outside, spiritual practice or honest conversation gives them precisely the doorway they were looking for. Others will choose to explore natural medicine within the boundaries of Colorado law and with appropriate professional guidance.
Johnny's story did not become meaningful because a mushroom magically repaired his life. It became meaningful because an experience helped him encounter things he could no longer continue carrying in silence, and because he chose to do something with what he encountered. That's the part of this conversation worth protecting.
What helps you become more honest, more present and more responsible for the life you are creating?
Perhaps modern science and ancient wisdom don't need to defeat one another. Science can teach us to measure. Tradition can remind us to respect. Law can create boundaries. Facilitation can create a safer container. Integration can return the insight to ordinary life. And nature can continue doing what it has done long before any of us arrived: teaching without demanding that we understand everything at once.
Listen carefully. Question boldly. Respect what you don't know. And never surrender responsibility for your own life. That may be the beginning of real wisdom.

Heal yourself, then your family, then the world.
