Choosing an ayahuasca retreat is a consequential decision. The gap between a well-run program and a risky one is almost entirely about protocols and staffing. As ayahuasca retreats have proliferated, so have underprepared operations. This guide gives you objective criteria to evaluate any ayahuasca retreat center — and shows how Sanctuary Tulum's licensed program has operated since 2011.
Eight Criteria for a Reputable Ayahuasca Retreat
1. Comprehensive medical screening
The most important safety criterion. Ayahuasca's MAO-inhibiting alkaloids interact dangerously with SSRIs, certain blood-pressure medications, and other common drugs.2 A reputable retreat requires a full medical history, cardiac and psychiatric screening, and a medication review before any ceremony is scheduled.
2. On-site medical personnel during ceremonies
A physician "available by phone" is not the same as one physically present. Ayahuasca can produce intense physical and emotional experiences that require immediate, in-person support.
3. Experienced, trained facilitators
A facilitator's role is to hold a safe container, guide participants through difficult material, and respond skillfully when hard experiences arise. Verifiable years of ceremonial practice in authentic lineages matter.
4. Small groups — or private ceremonies
Retreats that pack 20–50 people into a ceremony space are prioritizing revenue over safety. Sanctuary Tulum runs private, one-on-one ceremonies for each guest.
5. Integration support — before and after
A ceremony without integration is like surgery without recovery care. Look for skilled integration therapists working with guests between sessions and in the weeks following.3
6. A comprehensive surrounding program
Ayahuasca works best as the core of a broader protocol — nutrition, bodywork, breathwork, yoga, and integrative medical therapies. At Sanctuary Tulum, ceremony work sits inside the Pouyan Method™.
7. A verifiable track record
How long has the center operated? What is its safety record? What do former guests say? Sanctuary Tulum has operated since 2011 and, under our protocol, has not had a fatality during ayahuasca ceremonies.
8. Legal, licensed operation
Reputable centers operate as licensed medical facilities, not informal retreats. Sanctuary Tulum is licensed in Tulum, Mexico.
Warning Signs of a Risky Ayahuasca Retreat
- ❌ No required medical screening before booking
- ❌ Ceremonies in hotel rooms, rental properties, or informal spaces
- ❌ No licensed medical personnel on-site
- ❌ Large group ceremonies (20+ per facilitator)
- ❌ No integration support
- ❌ Facilitators without verifiable training
- ❌ Unusually low pricing or pressure to book immediately
- ❌ Unable to provide a documented safety record
Questions to Ask Before You Book
A short, direct list you can send by email: Is the facility medically licensed, and can you send the license number? Is a physician physically present during ceremony? What is your written cardiac and psychiatric screening protocol? How do you handle SSRI, tramadol, and blood-pressure medication tapers before ceremony? How large are ceremony groups? What integration is provided in the days following? What is your safety record and how many ceremonies have you run? Honest programs answer these in specifics; risky ones deflect.
How Sanctuary Tulum Measures Up
Founded in 2011 and licensed, Sanctuary Tulum runs ayahuasca work under physician supervision alongside ibogaine, 5-MeO-DMT, and psilocybin programs. Guests receive mandatory medical screening, on-site physicians during each ceremony, private ceremonial sessions, extensive one-on-one integration hours, and the full Pouyan Method™ protocol in a private oceanfront setting. Published trials show ayahuasca can produce rapid antidepressant responses in treatment-resistant depression,1 though effect sizes vary and the trial literature remains small.

Medical Screening — The Distinguishing Variable
The most reliable single indicator of retreat quality is whether meaningful medical screening happens before ceremony access is granted. A well-run program requires a cardiovascular history, ECG where indicated, full medication reconciliation, and a psychiatric history that captures personal and first-degree family history of psychotic and bipolar illness. Serotonergic medications must be tapered on a physician-supervised schedule; guests who cannot safely taper are not admitted to the plant medicine arc.
Retreats that skip these steps have a lower barrier to entry and a materially higher adverse-event risk. That is the trade-off, and it is worth naming plainly when comparing options.
Facilitator Ratios, Language, and Aftercare
Ceremony ratios matter. A single facilitator managing eight or more guests through a full ayahuasca session cannot deliver the individual attention the medicine requires. Sanctuary Tulum staffs to a ratio that keeps a trained facilitator physically close to each guest during the onset and peak. English-speaking facilitators, medical staff on site during ceremony, and structured integration hours in the days after are the operational markers separating a durable clinical program from a ceremony tourism model.
Aftercare is the piece that most retreats under-deliver. A written integration plan, structured check-ins for months after departure, and a physician-reviewable medical summary of the stay are what turn a powerful session into durable change. Related: ayahuasca ceremonies.
