The short answer: good psilocybin therapy screening asks about your personal and family history of psychosis or bipolar disorder, your cardiac health, and every medication you currently take — particularly serotonergic ones — before it asks anything about scheduling. This article is educational and is not medical advice; whether psilocybin therapy is appropriate for you is a decision for a qualified physician who knows your full history.
1–3: Psychiatric History Comes First
1. Do you screen for personal or family history of psychosis? This is one of the most consequential exclusions in the field. Ask directly how the screening is conducted and what happens if a family history is disclosed but not fully understood.
2. Do you screen for bipolar disorder? Psilocybin has been associated with concerns around triggering manic episodes in vulnerable individuals. Ask whether this is asked about specifically, not folded into a general mental health question.
3. Who reviews the screening results, and can they decline participation? A program should have someone clinically qualified making the final call, with the authority to say no. If everyone who applies is accepted, that is a sign screening is not being taken seriously.
A good answer to the family-history question sounds specific: it names which relatives count, how far the questionnaire reaches (parents and siblings, typically, sometimes grandparents), and what happens when a participant is unsure of a relative's diagnosis. A vague answer treats "any mental health history in your family" as a single yes-or-no box, which misses the distinction between, say, a family history of depression and a family history of psychotic illness. Ask, too, what happens if you are declined — some programs will suggest other forms of support or refer you elsewhere, while others simply end the conversation. How a program handles a "no" tells you almost as much about its seriousness as how it handles a "yes."
4–6: Cardiac and Physical Health Considerations
4. Is cardiac history part of the intake? Ask whether blood pressure, heart rate, and any cardiac history are reviewed, and what conditions would disqualify a participant.
5. Are age or other physical health factors considered? Ask how the program adjusts its approach, if at all, for participants who are older or who have other relevant health conditions.
6. Is there a physician involved in physical health screening, not only mental health? A complete screening addresses both, and a program should be able to describe how the two assessments connect.
Practically, this stage of screening should involve more than a checkbox questionnaire. Ask whether blood pressure and resting heart rate are actually measured, rather than self-reported, and whether the program asks about symptoms like chest pain, palpitations, or fainting history. Ask what happens if something concerning turns up — is there a process for requesting records from your own physician, or a referral for further evaluation before a decision is made? Programs vary in how far they go here, and a program that is willing to pause and ask for outside medical information, rather than making a snap judgment on the day, is generally taking the physical side of screening more seriously.
7–8: Medication Review
7. How do you handle current SSRIs or SNRIs? Serotonergic medications can interact with psilocybin and may reduce its effects. Ask how the program addresses this, and whether any changes to medication are ever suggested — a serious program will say that medication changes are a decision for your prescribing physician, not for a retreat team. Our comparison of psilocybin and SSRIs covers this in more depth.
8. What other medications or substances are asked about? Ask whether the intake covers recreational substance use, other prescriptions, and supplements, since a partial medication history is not a complete safety picture.
Get specific about how this conversation actually unfolds. A thorough intake will ask not only what you currently take but for how long, at what dose, and whether you have missed doses recently, since all of that can matter. It should also ask about supplements and over-the-counter products, some of which have their own serotonergic activity, and about any recent changes to your medication regimen. What it should never do is suggest that you adjust or pause a prescribed medication on your own in order to qualify — that decision, if it is ever appropriate, belongs to the physician who prescribed the medication, working on their own timeline and with their own follow-up plan.
9–10: Set, Setting, and Legal Context
9. How does the program address set and setting, and who monitors the session? Ask about preparation conversations beforehand, the physical environment during the session, and whether trained staff are present throughout rather than checking in periodically. Our magic mushroom ceremony guide describes what a monitored setting typically involves.
10. What is the legal basis for offering psilocybin therapy where you operate? Legal status varies by country and changes over time. Ask specifically, and do not assume that legality in one place applies elsewhere. Our overview of psilocybin therapy in Mexico discusses this context.
On the practical side, ask what a typical preparation conversation covers before a session and how far in advance it happens. A single call the day before is a different level of preparation than several conversations spread over weeks that let you actually think through your intentions and ask questions as they come up. During the session itself, ask how many trained staff are present relative to participants, whether that ratio changes for group versus individual sessions, and what their role is if a participant becomes distressed. On the legal question, ask for this in plain terms rather than accepting general reassurance — a program should be able to explain, concretely, why what they offer is permitted in their specific location, and you are entitled to ask for that explanation before committing your time and money.
Why Screening Exists in the First Place
Psilocybin screening is not bureaucratic paperwork designed to slow you down before an experience you have already decided to have. It exists because psilocybin can meaningfully affect people with certain psychiatric or cardiac vulnerabilities in ways that are difficult to predict from the outside, and because the setting a person is in when those effects occur matters enormously. A screening conversation that feels rushed, that accepts vague answers, or that seems designed to get you to a "yes" rather than an honest assessment is not protecting you. Ask, early in any conversation with a program, who actually reviews your intake and what their clinical background is. A good answer names a specific role — a psychiatric nurse practitioner, a physician, a clinical director — and describes a process with defined steps. A vague answer talks about "our team" without ever naming who is on it.
It is also worth understanding what screening cannot do. No intake questionnaire, however thorough, can guarantee that a session will go a certain way, and no program should imply otherwise. What good screening does is reduce avoidable risk by identifying the situations where the risk profile changes meaningfully — a personal or family history of psychosis, an unstable cardiac condition, a medication that interacts with psilocybin — and by being willing to say no when those situations are present. If you disclose something during intake and a program still says yes without any further discussion, that is worth noticing.
A Short Checklist Before You Apply
- Explicit screening for personal or family history of psychosis or bipolar disorder
- Cardiac and physical health review by qualified staff
- A complete medication history, with serotonergic medications specifically addressed
- A named clinician with authority to decline participation
- A described preparation process and monitored setting
- A clear statement of the legal basis for the program where it operates
If a program can answer each of these clearly, screening is being taken seriously. To ask about your own situation, reach our team through the contact page.
