Psilocybin mushrooms are rising in popularity. They can potentially treat mental health disorders, promote personal growth, and boost creative insights. But there is still a lot of mystery and misinformation surrounding this fantastic fungus. Many people ask questions about how to consume them, what the effects are, and how they can be therapeutically beneficial. What we get asked most often is, “are mushrooms legal in Colorado?”

Yes, mushrooms are legal in Colorado, but there is a lot of nuance to consider. The legal landscape is always changing at both the State and Federal level. A few states have made mushrooms legal and have regulated the practice of psilocybin therapy, including Oregon and Colorado. In the coming years, more states plan on introducing bills to legalize and regulate their use. 

If you are curious about the benefits of psilocybin therapy, you need to understand the law. This is important to make informed decisions about your personal use. It also ensures safe access to trusted professionals.

What are Psilocybin Mushrooms?

Psilocybin is a naturally occurring psychoactive compound found in certain species of fungi. The most widely recognized species containing psilocybin is Psilocybe cubensis, though several others also possess this compound. These mushrooms are commonly referred to as Psilocybin Mushrooms, Magic Mushrooms, Boomers, or simply ‘Shrooms.’

In Colorado, mushrooms are legal for therapeutic purposes. This is done through an evidence-based process. It is based on the understanding of how they create changes in the brain. When ingested, psilocybin acts on serotonin receptors, which is how the psychedelic effects of magic mushrooms are created. Interestingly, this is also what facilitates increased neuroplasticity (the process of the brain restructuring)

Historically, cultures from all over the world have used psilocybin mushrooms for ceremony and healing. This ancient practice has been especially prominent in Central and South America. Mushroom ceremonies were performed to connect with the natural world, gain insights, and honor ancestors. 

Due to exploitation, they became popular in the Western world in the 1950s. The counter-culture of the 1960s brought even more attention to mushrooms and other psychedelics. Psilocybin mushrooms were banned by the United States federal government in 1968. This was aimed at suppressing the anti-war movement and erasing indigenous practices. The Controlled Substance Act was passed in 1970, which classified psilocybin mushrooms as a Schedule I drug. The government determined that it had a high potential for abuse and no medical applications. For decades, it was illegal even to study mushrooms and other psychedelic substances.

Today, there are legal ways for researchers to study their benefits. This is paving the way for legalization in states across the US. Science is showing how powerful their healing properties can be. Current research shows they are non-addictive with a very low potential for abuse. Additionally, they have medical applications that we are finally beginning to understand.

Are Mushrooms Legal In Colorado?

In 2022, Colorado voters passed Proposition 122 — now known as the Natural Medicine Health Act (NMHA) — making it the second state in the U.S. to create a legal pathway for psilocybin-assisted therapy. This legislation decriminalized certain natural medicines for personal use and created a framework to allow regulated therapeutic access.

As of 2025, psilocybin can be administered legally in Colorado only at licensed healing centers by licensed facilitators, following a structured process that includes screening, preparation, administration, and integration. This is a professional, regulated model rooted in harm reduction and healing, not recreational use. Go Within Collective holds the second healing center license issued by Colorado, NMHC-00002.

Other natural medicines are decriminalized for personal use but are not yet part of the regulated program. These are under review for possible inclusion in 2026. They include mescaline (not derived from peyote), ibogaine, and DMT.

The Therapeutic Benefits of Psilocybin Mushrooms

Though restricted for decades, recent clinical research suggests psilocybin may support relief from:

• Depression (including treatment-resistant forms)
• Anxiety
• PTSD and trauma
• OCD
• Substance use disorders
• End-of-life distress in terminal illness

Psilocybin therapy is showing benefits for depression and anxiety in patients who are receiving end-of-life care due to terminal cancer. In a randomized double-blind trial published in the Journal of Psychopharmacology, the researchers concluded that “when administered under psychologically supportive, double-blind conditions, a single dose of psilocybin produced substantial and enduring decreases in depressed mood and anxiety along with increases in quality of life and decreases in death anxiety in patients with a life-threatening cancer diagnosis.” Many report that consuming mushrooms was the single most important event in their life.

One review and meta-analysis published in the Journal of Affective Disorders found that “psilocybin has a rapid, sizable, and long-term anti-depressive effect for primary (major depression patients) and secondary depressive disorder (depressed cancer patients)”.

Another review published in the Journal of Psychoactive Drugs found that psilocybin “is beginning to demonstrate potential for treating psychiatric disorders related to anxiety, depression, and substance use.” The researchers called for more robust research to further study therapeutic benefits.

Renowned institutions such as Johns Hopkins and Imperial College London are at the forefront of psychedelic therapy research. They are conducting research that includes fMRIs to study not only the therapeutic benefits, but also how the brain is rewired by psilocybin through a process known as neuroplasticity.

Psilocybin is non-addictive, has a low potential for misuse, and promotes measurable changes in brain activity and connectivity. However, it’s not right for everyone. Psilocybin should never be used without medical and psychological screening — especially for individuals with certain psychiatric diagnoses or those taking medications. Discussing psilocybin-assisted therapy with your medical or mental health professional is advised.

More studies are needed to further understand psilocybin therapy. We need to determine how it works and who exactly can benefit. Further research is crucial to establish protocols to increase the likelihood of a positive outcome. It is also important to note that the current studies are conducted on selected individuals. Therefore, outcomes outside of a clinical trial setting are less predictable. 

Go Within Collective is dedicated to keeping up-to-date with the latest research and following best practices. While there is no “cure” or guaranteed outcome, following evidence-based practices increases the chance of lasting, positive change. These practices benefit those who seek therapeutic outcomes.
