Colorado has recently joined Oregon as the second state to legalize psychedelic psilocybin therapy, marking a significant milestone in mental health treatment. This development, which took effect in January 2025, follows a 2022 ballot measure that set the stage for a two-year regulatory process.
As the state prepares to launch its regulated psychedelic therapy program, it's poised to reshape the landscape of mental health care and offer new hope to those struggling with conditions like depression and PTSD.

The Path to Legalization
In November 2022, Colorado voters approved Proposition 122, which decriminalized the personal use of psilocybin mushrooms and paved the way for therapeutic applications. This decision initiated a two-year rulemaking period to establish guidelines for treating various mental health conditions.
The proposition passed with 53% of the statewide votes but notably received even stronger support in many of Colorado's High Country counties. Pitkin County showed the second-highest margin of approval at 76%. At the same time, Summit, Routt, and Eagle counties also demonstrated significant support with approval rates of 65%, 63%, and 62%, respectively.
Current Status and Licensing
As of January 2025, individuals and companies can apply for licenses to administer psilocybin therapy. The Colorado Department of Regulatory Agencies (DORA) and the Department of Revenue (DOR) began accepting applications on December 31, 2024. While applications are being processed, treatments may not be available for several months.

The first healing centers – the state's term for businesses offering psilocybin therapy – are expected to be operational and accepting patients by late spring or early summer of 2025. This timeline allows for thorough vetting of applicants and ensures all safety protocols are in place before treatments begin.
Regulatory Framework
Psilocybin therapy in Colorado is subject to stricter regulations compared to marijuana, reflecting the state's commitment to safety and efficacy:
- No recreational dispensaries will be allowed
- Treatment will be confined to licensed businesses and therapy sessions
- Licensed facilitators will be required to oversee all sessions
- Patients must undergo risk assessment and preliminary meetings
- Continuous support will be provided during sessions
- Testing and regulation of psilocybin production will be enforced
The therapy model in Colorado will follow four basic steps: screening, preparation, administration, and integration. This approach mirrors Oregon's model but incorporates improvements based on lessons learned from their program.
The Treatment Process
- Screening: Patients will complete a thorough screening process to match with a psilocybin facilitator best suited to their needs.
- Preparation: The facilitator creates a patient safety plan and sets treatment expectations.
- Administration: Psilocybin is administered in a controlled setting, with the patient-guided and overseen by a licensed facilitator.
- Integration: The facilitator continues to work with the patient to integrate insights gained during the session into daily life and provides additional support.

Within these steps, Colorado has implemented several "guardrails" to ensure patient safety. These include requirements for facilitator supervision duration, patient transportation plans after sessions, individualized safety plans, age restrictions, and storage requirements for the substance.
Challenges and Controversies
Despite statewide legalization, some conservative areas are imposing restrictions on healing centers. In Colorado Springs, for example, the city council extended prohibition zones for these centers from 1,000 feet to 1 mile from specific locations, such as schools.
This decision has sparked debate between conservative leaders and advocates, particularly veterans who support more straightforward access to psilocybin therapy for PTSD treatment.
The clash in Colorado Springs highlights the tension between local control and statewide policy. While Proposition 122 prohibits localities from banning healing centers outright, it does allow for regulation of the time, place, and manner of their operation.
Potential Benefits and Concerns
Research suggests psychedelic therapy may help with various conditions:
- Alcoholism
- Depression
- PTSD
- End-of-life distress
- Obsessive-compulsive disorder (OCD)
- Cluster headaches
- Various addictions
However, experts like Dr. Jeffrey Lieberman from Columbia University caution about moving too quickly, citing concerns such as:
- Potential misuse
- High out-of-pocket costs
- Risks for certain mental health conditions
It's important to note that while psilocybin is physiologically safe for most people – meaning there's no risk of overdose or physical dependence – the required safety screening will help address potential risks for individuals with certain conditions.
The Veterans' Perspective
Many veterans, like Lane Belone, a special forces veteran, advocate for psilocybin therapy based on personal experiences. They cite potential benefits such as:
- Processing trauma more effectively
- Addressing anxiety and PTSD symptoms
- Offering hope where traditional treatments have failed
Veterans have become flagbearers for psychedelic therapy, particularly in treating PTSD. Their advocacy has helped to set psilocybin therapy apart from other politically charged drug policies, even garnering some conservative support.
Training and Education
As the program launches, education and training for facilitators are crucial. Institutions like Naropa University in Boulder are already offering state-licensed training programs for future psychedelic therapy providers.
Sara Lewis, director of training and research at the Naropa Center for Psychedelic Studies, emphasizes the critical importance of education in this new field.
Economic and Social Impact
Introducing psilocybin therapy is expected to create jobs and boost local economies. However, it also raises questions about insurance coverage and accessibility, as insurance plans may not initially cover treatments.
Looking Ahead
As Colorado navigates this new therapeutic landscape, the balance between access and safety remains crucial. The state's approach could set a precedent for future psychedelic therapy programs nationwide, potentially reshaping mental health treatment options for millions.
Key points to watch as the program unfolds include:
- The speed and efficiency of the licensing process
- The geographic distribution of healing centers across the state
- Potential adjustments to regulations based on early experiences
- The response from the medical community and insurance providers
- Ongoing research into the efficacy and long-term effects of psilocybin therapy
Colorado's pioneering efforts in psychedelic therapy represent a paradigm shift in mental health care. By offering a new tool in the treatment of various mental health conditions, the state is opening doors to potentially transformative experiences for many individuals.
As healing centers begin to open their doors in 2025, Colorado will be at the forefront of a new era in mental health treatment, balancing innovation with careful regulation to ensure the safety and well-being of its residents.
