Colorado holds a unique place in the American story of plant medicine. If you searched for "ayahuasca retreat Colorado" from Denver, Boulder, Colorado Springs, or a mountain town in between, you have probably read that ayahuasca is now legal in your state. You may have seen ceremonies advertised with a confidence you will not find anywhere else in the country.
The truth is more nuanced, and the nuance matters deeply for your safety and your healing. Ayahuasca is decriminalized in Colorado, not legalized, and no licensed ayahuasca retreat exists anywhere in the state. The difference between those two words shapes everything about what is actually available to you, who is offering it, and what protections exist when you sit down in ceremony.
This guide explains exactly what Colorado's Natural Medicine Health Act changed and what it did not, why the state's pioneering psilocybin program does not extend to ayahuasca, what the ceremonies operating in Colorado's legal gray zone can and cannot offer, and why a question deeper than legality leads so many Coloradans to the medicine's true home in Peru. We have guided guests through traditional Shipibo ceremonies in the Amazon and Sacred Valley for more than a decade, and Coloradans arrive at our centers with a curiosity already ahead of the national conversation. This page is written in that same spirit of honesty.
The most accurate answer is that ayahuasca is decriminalized in Colorado for personal use, but it is not legal to sell, and there is no licensed pathway for ayahuasca retreats or paid ceremonies. Colorado has removed criminal penalties for adults; it has not created a legal ayahuasca industry.
In November 2022, Colorado voters passed Proposition 122, the Natural Medicine Health Act. The measure did two distinct things, and the distinction is the key to this entire topic.
First, it decriminalized the personal use, possession, cultivation, and sharing of five natural psychedelics for adults 21 and older: psilocybin, psilocin, DMT, ibogaine, and mescaline not derived from peyote. Because ayahuasca is a brew of DMT-containing plants, personal use of ayahuasca falls under these protections. An adult in Colorado can possess and share the medicine without state criminal penalty, so long as no money changes hands for the medicine itself.
Second, it created a regulated program of licensed healing centers and trained facilitators. This is the part most articles blur, and it is where seekers get misled: the regulated program currently covers psilocybin and psilocin only. Licensed facilitators in Colorado may legally guide psilocybin sessions. They may not legally offer ayahuasca, and no healing center in the state is licensed to serve it.
Colorado's openness to plant medicine did not begin with the statewide vote. In May 2019, Denver became the first city in the United States to decriminalize psilocybin mushrooms, a citizen-led initiative that signaled how seriously Coloradans had begun to take these medicines. Proposition 122 carried that momentum statewide three years later, passing with just over 52 percent of the vote and making Colorado the first state in the nation to extend decriminalization beyond psilocybin to DMT and other natural medicines. It is a remarkable arc, and it is worth understanding precisely because of how much ground it covered and where it stopped.
DMT is decriminalized in Colorado, not legal. Adults 21 and older are protected from state criminal penalties for personal use, possession, and sharing of naturally derived DMT, including ayahuasca. Retail sale remains prohibited, synthetic DMT is excluded from these protections entirely, and DMT remains a Schedule I controlled substance under federal law. Colorado's protections also stop at the boundaries of state authority: they do not apply on federal land, which is worth pausing on in a state where national forests and parks cover so much of the map.
Possibly, and this is where Colorado's story is still being written. Under the law, DMT and mescaline became eligible for addition to the regulated program on June 1, 2026, but only if the state's Natural Medicine Advisory Board recommends it and regulators approve. As of this writing, that window has just opened and no rule adding DMT has been adopted. The board's first expansion recommendation went to ibogaine, in late 2025. Until and unless DMT is formally added and rules are written for it, licensed ayahuasca services remain a possibility on the horizon rather than a reality you can book.
Put the pieces together and the picture becomes clear. Personal use is protected. Licensed facilitation covers psilocybin only. Selling natural medicine outside the licensed system remains illegal. So where does that leave the ayahuasca ceremonies you can find advertised in Denver and Boulder?
They live in a gray zone. Organizers generally rely on the personal-use and sharing provisions, structuring payment as a donation, a venue fee, or a charge for everything except the medicine itself. Whatever the legal merits of those arrangements, here is what the gray zone means for you as a guest: none of the protections that Colorado so carefully built for its psilocybin program apply to the ceremony you would be attending.
None of this means every ceremony in Colorado is reckless. It means decriminalization removed the penalty without adding any of the protections, and you deserve to know that before you sit.
There is also a question here that runs deeper than statutes, and Coloradans, who voted for the Natural Medicine Health Act out of genuine respect for these medicines, may feel it more keenly than anyone.
What Colorado granted in 2022 was permission. What it could not grant, because no law can, is lineage. The Shipibo tradition that carried ayahuasca through the centuries is not a technique that transfers in a training weekend. It lives in healers who began their apprenticeships as children, in extended plant dietas that last months and years, in icaros received and refined across generations, and in a relationship with the plants that begins in the soil where they grow. A decriminalized brew served in a rented studio along the Front Range may be legal enough. Whether it carries the medicine's tradition is another question entirely.
We say this with respect for what Colorado is attempting. The state's deliberate, safety-focused approach to psilocybin is admirable, and its advisory board includes voices for indigenous and religious use precisely because lawmakers understood that these medicines come from somewhere and from someone. That instinct points to a truth the gray zone cannot honor: ayahuasca has a home, a people, and a way it has always been done. For those who feel called to meet the medicine fully, the most direct path is not to wait for the regulations to catch up. It is to go where the tradition has never been interrupted.
At Arkana, we offer authentic ayahuasca experiences at two sacred locations in Peru. Each carries its own medicine, its own teachings, its own perfect timing for different souls.

In Peru, ayahuasca is fully legal, and more than legal: in 2008 the Peruvian government declared the traditional knowledge and use of ayahuasca by Amazonian indigenous communities part of the nation's cultural heritage. Ceremony is not a gray zone there. It is a living institution, practiced openly, protected by law, and woven into the identity of the peoples who carry it.
That openness changes the practical realities that the Colorado gray zone leaves unresolved. Centers in Peru operate publicly and can be researched, reviewed, and held to account. Medical screening involves physicians and happens before you ever board a plane. Healers practice under their own names, within traditions whose elders and communities know them. And the medicine itself never needs to be smuggled, because it is brewed where it grows.
Arkana's ayahuasca comes from a 100-acre plantation in Vencedor, a Shipibo community on the Pisqui River. It is tended by Maestro Cesar, known as Paparahua, who was born there and returns between retreats to care for the plants. The vine is grown, harvested, and cooked by the same family who will sing over you in ceremony, and it travels only the short distance from their land to the maloca where it is served.
This is the principle we hold that no decriminalization measure can replicate: the medicine should not travel far from the soil and the hands that raised it. In the Shipibo understanding, ayahuasca is a relationship among plant, healer, land, and song. Any brew that reaches Colorado has been severed from that relationship and carried through illegal channels by definition, with everything about its preparation left to trust. In Peru, the seeker travels to the medicine, just as it has been done for generations, and arrives to find the relationship intact.
Ceremonies at Arkana are led by a multi-generational Shipibo family headed by Maestra Justina, a direct descendant of the Merayas, the most revered rank of healer in the Shipibo tradition. Her preparation spans more than 45 years and over 50 plant dietas, and she practices shamanic surgery weekly, an ability so rare that even seasoned curanderos may never witness it. Alongside Maestro Cesar's five decades of practice and the work of Maestro Eligio, also born in Vencedor, the healing team brings more than a century of combined experience into every ceremony. This is what an uninterrupted lineage looks like, and it is the difference between receiving a substance and being received by a tradition.
Guardianship, not ownership. Our Shipibo healers lead every ceremony because the medicine is theirs to give. Our facilitators hold the space around them, translate, and support. We consider ourselves guardians of this wisdom on behalf of the people it belongs to.
Reciprocity with Vencedor. Our relationship with the community that grows our medicine is one of family, employment, and long-term investment, so that the lineage we depend on continues to flourish at its source.
Safety held in the open. Every guest completes a medical evaluation and phone consultation before arrival, followed by a three-week preparation diet. Our Medical Director, Dr. Arturo J. Sáenz Quintanilla, oversees screening. Ceremonies are held with three to seven Shipibo healers and a one-to-three facilitator-to-guest ratio, dosing is personalized, and every guest is monitored through the night. Across more than a decade and thousands of guests, Arkana has maintained a perfect safety record, and every safeguard behind it operates legally and transparently, the way this work deserves.
Integration as a way home. Insights from ceremony are meant to live in your daily life back in Colorado. Our 8P Method of Integration, lifetime community access, and ongoing facilitator check-ins exist to carry the work forward long after you leave Peru.
And for Coloradans specifically, one more invitation. Our Sacred Valley center sits along the Vilcanota River between Cusco and Machu Picchu, in Andean mountain country that feels, to many of our guests from the Rockies, like a landscape their soul already recognizes. Mountain people tend to understand the Sacred Valley the moment they arrive. Many Coloradans find that working with the medicine surrounded by peaks, rather than jungle, is the setting their healing was asking for, while our Amazon center offers the full rainforest immersion for those drawn to the medicine's birthplace.
It helps to make the comparison concrete. A gray-zone ceremony in Colorado is typically a single night, or a weekend, organized around the medicine alone. A retreat in Peru is a complete arc of healing, made possible precisely because nothing about it needs to stay quiet.
At Arkana, preparation begins three weeks before you arrive, with a guided diet and a medical review overseen by our medical team. A seven-day retreat then weaves ayahuasca ceremonies together with a San Pedro ceremony, hapé ceremony, breathwork, sound healing, and yoga, while the Shipibo healers prescribe individual plant treatments based on what they observe in ceremony. Fourteen-day and twenty-one-day retreats deepen the work further. Between ceremonies there is rest and real comfort: ensuite rooms, organic farm-to-table meals prepared in alignment with the ayahuasca diet, spa therapies, and, in the Sacred Valley, a float tank, an open-air gym overlooking the mountains, and excursions to Machu Picchu and the Maras Salt Mines for multi-week guests.
And when you return home to Colorado, the work continues through our 8P Method of Integration, lifetime community access, and ongoing facilitator check-ins. A ceremony can open a door. A retreat, held within a legal and living tradition, walks you all the way through it and back.
From Denver International, Peru is closer than it feels. A single connection through a hub such as Miami, Dallas, Houston, or Atlanta puts you in Lima, and from there a short domestic flight reaches either of our Peruvian centers: under two hours to Iquitos for the Amazon, or about an hour and a half to Cusco for the Sacred Valley. Most guests complete the journey in a single travel day. Measured against the months or years that the Colorado regulatory process may still take, a day of travel is a small distance to cross for a tradition that has been waiting, unbroken, the whole time.
Ayahuasca is decriminalized in Colorado, not legal. Adults 21 and older are protected from state criminal penalties for personal use, possession, and sharing under the Natural Medicine Health Act. Selling ayahuasca remains illegal, no retreat or healing center is licensed to serve it, and DMT remains a Schedule I substance under federal law.
Naturally derived DMT is decriminalized for personal use, possession, and sharing by adults 21 and older in Colorado. It is not legal to sell, synthetic DMT is excluded from the protections, the state's licensed healing centers cannot offer it, and federal law still classifies DMT as Schedule I, including on federal land within Colorado.
No. Colorado's licensed healing centers and trained facilitators are currently authorized to work with psilocybin only. Any ayahuasca ceremony operating in Colorado today does so under the personal-use and sharing provisions, outside the licensed system and its safeguards.
It may. As of June 1, 2026, state law allows DMT to be added to the regulated natural medicine program if the Natural Medicine Advisory Board recommends it and regulators approve. No such rule has been adopted as of this writing, so licensed ayahuasca services remain a future possibility rather than a current option.
Safety depends entirely on the individual organizer, because no licensing, screening, testing, or oversight requirements apply to gray-zone ceremonies. Before considering one, ask who trained the facilitator and in what lineage, where and when the medicine was brewed, how participants are screened for medications and health conditions, and what the emergency plan is. Clear, confident answers to all four are the minimum this work requires.
Yes. Ayahuasca is fully legal in Peru, and the traditional knowledge and use of ayahuasca by Amazonian indigenous communities was declared part of Peru's national cultural heritage in 2008. Retreat centers there operate openly, lawfully, and within living indigenous traditions.
Colorado has done something genuinely historic, and if you are searching from within the state, you are part of a community that takes these medicines seriously. Honor that seriousness fully. The law where you live offers permission. The tradition in Peru offers everything else: legality without asterisks, healers formed by a lifetime of preparation, medicine grown in its own soil by the family who serves it, and safety practiced in the open rather than improvised in a gray zone.
If you would like to explore whether an Arkana retreat in the Sacred Valley or the Amazon is the right fit for your intentions, we would be honored to talk it through with you. Your healing deserves more than what is permitted. It deserves what is true.
