How to choose a provider responsibly.

The non-negotiables

Any responsible plant medicine provider — regardless of medicine, modality, or framework — will do all of the following. If they don't, look elsewhere.

• A real medical and psychological intake. Not a checkbox form. Detailed questions about medications, medical history, psychiatric history (yours and family), and current life circumstances.
• Honest exclusion criteria. They turn people away. If a provider accepts everyone, that is itself the red flag. Conditions that should typically result in non-acceptance include active psychosis, recent suicide attempts, certain cardiac conditions, pregnancy, and uncontrolled severe mental illness.
• Medication review and tapering protocols. SSRIs, MAO inhibitors, lithium, and a number of other medications interact dangerously with various plant medicines. A serious provider will know which medications require tapering, will coordinate the timeline with your prescribing physician, and won't proceed without that being properly handled.
• Trained facilitators with real experience. Ask how many sessions they've personally facilitated, who trained them, and how long they've been doing this work. Specific names, specific numbers.
• Structured integration support. The session is the smaller part of the work. Integration — the weeks and months after — is where most of the change actually happens. Reputable providers offer or coordinate post-session support.
• Clear emergency protocols. What happens if someone has a psychiatric emergency, a medical emergency, or both? Where is the nearest hospital? What's the response time? Who makes calls?

Medicine-specific considerations

Ibogaine — cardiac screening is mandatory

Ibogaine prolongs the QT interval and can trigger fatal arrhythmias in vulnerable patients. Any clinic offering ibogaine without a pre-treatment ECG, continuous cardiac monitoring during dosing, and immediate access to advanced cardiac life support is operating below the safety standard. Most known ibogaine fatalities occurred in unsupervised settings. See ibogaine clinics with verified medical standards.

Ayahuasca — MAO interactions are real

The β-carbolines in ayahuasca are reversible monoamine oxidase inhibitors. Combining with SSRIs, certain other antidepressants, stimulants, or tyramine-rich foods can cause serotonin syndrome — a serious and potentially fatal condition. Tapering protocols must start weeks in advance. A provider who tells you "it'll be fine" without reviewing your medications in detail is not the provider you want.

5-MeO-DMT — lithium is a hard contraindication

Combining 5-MeO-DMT with lithium has been associated with seizures. This is a non-negotiable contraindication. Cardiovascular conditions are also a typical exclusion given the transient but significant blood pressure changes. More on 5-MeO-DMT safety.

Psilocybin — psychiatric history matters

Personal or family history of schizophrenia, schizoaffective disorder, or first-episode psychosis is a typical exclusion criterion. Bipolar I disorder is generally also exclusionary, particularly with a history of manic episodes. Severe personality disorders need careful consideration with experienced providers.

Kambo — physical screening, not psychiatric

Cardiac conditions, pregnancy, recent surgery, and active eating disorders are typical contraindications. The fatal cases on record almost universally involve providers who allowed excessive water consumption before sessions, leading to fatal hyponatremia. A practitioner who controls water intake carefully is doing their job.

Red flags — walk away from any of these

• "Everyone can benefit, the medicine knows what each person needs." This sentiment, however earnestly meant, masks an unwillingness to screen properly.
• No medical professional involved at all, for any medicine that requires medical oversight. Particularly ibogaine.
• Pressure tactics, scarcity messaging, or urgency around enrolment. "Only two spots left" applied to plant medicine retreats is a sales tactic, not a clinical reality.
• Refusal to provide specific information about facilitators' training and background.
• Combining multiple medicines in a single session, or in rapid sequence, without clear medical rationale. Some providers do offer thoughtful multi-medicine protocols (e.g., ibogaine followed by 5-MeO-DMT), but combinations should be explained and justified.
• Sexual contact between facilitators and participants, in any form, during or after the work. This is one of the most well-documented forms of harm in the plant medicine field.
• No integration support, or "integration" that's just a sales pitch for the next retreat.
• Pricing dramatically below the market rate. Quality medical-grade ibogaine treatment, for example, has real costs — physicians, ECGs, nursing, facility, medication. If something is one-third the typical price, ask what's being cut.

Questions worth asking a provider

1. What conditions would result in you not accepting me?
2. What does your medical screening process look like?
3. Who will be facilitating my session, and what's their training and experience?
4. What medications do you require me to taper, and how do we coordinate that with my prescriber?
5. What happens if I have a medical or psychological emergency during my stay?
6. What does your integration support look like — for how long, and in what format?
7. Can I speak to past participants?
8. Are you accredited by any oversight body? (For ibogaine, CSG accreditation from the Mexican Ministry of Health is meaningful.)

If something goes wrong

If you experience harm at a plant medicine retreat, the Psychedelic Wellness Coalition and the Chacruna Institute both run incident-reporting and survivor support programmes. The bar for reporting is "I'm uncertain whether what happened was appropriate" — you don't need to be sure first.
