Before You Book the Retreat: Eight Questions Your Medical History Requires You to Answer First
Retreat intake forms ask about medications but rarely probe the contraindications that matter, cardiac history, personal or family psychiatric history, seizure disorders, autoimmune conditions, and this article gives prospective attendees a structured pre-booking self-screen tied to the actual clinical evidence.
The retreat website looked reassuring. There was a photo of a quiet room, a facilitator with a warm bio, and an intake form that asked which medications you take. You filled it in, and nothing flagged. But the form asked about your prescriptions, not about your heart, your family, or the aunt nobody talks about. Before you put down a deposit, there are questions worth asking yourself that the form probably won't - because the deposit is refundable and your health is not.
These apply whether the retreat offers psilocybin mushrooms or truffles, MDMA, or both. Some risks are shared; some are specific to one substance. Where it matters, we say which.
Your heart: the question MDMA retreats underask
Afterglow
Of everything we tried for the comedown, this is the one that made a real difference to how we slept and how flat Tuesday felt. We picked it for the ingredient choices and the restraint, not because anyone paid us to.
Read the full review →MDMA raises heart rate and blood pressure, and it loads your cardiovascular system in a way that matters if that system already has a weakness. This is the clearest physical contraindication in the whole conversation, and it is the one glossed over most often.
Answer honestly:
- Do you have high blood pressure, a heart rhythm problem, or known heart disease?
- Have you had a heart attack, stroke, or been told about a heart murmur or valve issue?
- Is there a family history of sudden cardiac death or heart problems before age 50?
If any of these are yes, MDMA is a genuine cardiac risk, not a technicality. The evidence here is strong. For psilocybin the cardiac picture is milder, but it still raises heart rate and blood pressure modestly, which is worth weighing if your heart is already compromised.
🚨 Don't rely on the retreat to catch this.
If you have any cardiac history, get a real answer from a doctor before you book - ideally with an ECG. A warm facilitator is not a cardiologist, and an intake form is not a screening.
Psychiatric history: yours and your family's
This is the question that matters most for psilocybin, and the one retreats are most reluctant to press, because pressing it turns people away.
Psilocybin can trigger or unmask psychosis in people who are vulnerable to it. The signal is strongest for a personal or family history of schizophrenia or bipolar disorder. Most retreats screen out a personal diagnosis. Far fewer ask properly about family history, which also carries risk.
Ask yourself:
- Have you ever experienced psychosis, mania, or been diagnosed with bipolar disorder or schizophrenia?
- Does a first-degree relative - parent, sibling, child - have any of these?
- Have you had a dissociative episode or a period where reality felt unreal for days?
If yes, this is the single strongest reason to think twice, and it applies to both psilocybin and MDMA. The evidence linking these conditions to serious adverse psychedelic reactions is mixed in strength but consistent in direction, and the downside is severe enough that caution is warranted even on imperfect data.
A difficult psilocybin trip is not a brief chemical dip you sleep off. It is a psychological event, and for a vulnerable person it can set something in motion that outlasts the day.
Seizures and neurological history
Both substances lower the seizure threshold to some degree, and MDMA more clearly so, partly through its effects on body temperature and fluid balance.
- Do you have epilepsy or a seizure disorder?
- Have you had a seizure, even once, that wasn't fully explained?
- Do you have a history of serious head injury?
If so, raise it specifically. A generic "any medical conditions?" box does not prompt most people to mention a seizure from fifteen years ago.
Medications, especially the serotonergic ones
The intake form will ask what you take. What it may not explain is why certain combinations are dangerous.
- SSRIs, SNRIs, and other antidepressants blunt MDMA's effects and, more importantly, combining MDMA with them raises the risk of serotonin syndrome, which can be life-threatening.
- MAOIs combined with MDMA are especially dangerous and can be fatal.
- Lithium combined with psilocybin has been linked to seizures and serious reactions in case reports - this is an emerging but alarming signal, and worth taking seriously.
Timing matters.
Antidepressants are not something to stop on a whim or taper to suit a retreat date. Stopping them has its own serious risks. Any change belongs with the prescriber who put you on them, not a facilitator and not a countdown to a booking.
Autoimmune and other physical conditions
This is rarely on any form, and it should be on more.
- MDMA affects temperature regulation and fluid balance, which interacts badly with conditions affecting the kidneys or liver.
- Diabetes, thyroid disorders, and glaucoma deserve a specific mention.
- Pregnancy is a clear reason to wait for both substances.
The evidence for many of these is thinner than for the cardiac and psychiatric questions, but thin evidence in a self-administered retreat setting is still a reason to ask a doctor rather than assume.
What to do with your answers
If you answered yes to anything above, the move is not to hide it to get through the door. It is to get a straight medical opinion first - from someone who knows your history and has nothing riding on the booking.
And the plainest point of all: the lowest-risk option is always not to use. That is not a lecture, just the baseline every other choice is measured against.
A good retreat will welcome these questions and may even raise them first. A retreat that waves them away, or treats your caution as a lack of faith, has told you something useful about whether it deserves your deposit.
