When a retreat can help, and when it is too soon

Acute grief, in the first weeks and months, is not a time for a psychedelic retreat. The system is already flooded; what it needs is people, sleep, food and time. We generally ask that at least six months have passed since a major bereavement, longer if the death was sudden or traumatic, and that you are sleeping and functioning, however flatly. The guests who get the most from a retreat are usually a year or more on, stuck somewhere: still unable to look at photographs, still avoiding the room, still angry, or simply numb and tired of being numb. If a clinician has used the words "prolonged grief disorder" or "complicated grief" with you, bring that to the call; it is not a reason to exclude you but it changes how we prepare.

What the research says

The strongest evidence is from cancer patients facing their own death: two randomised trials at Johns Hopkins and NYU in 2016 found that a single high-dose psilocybin session, with preparation and integration, produced large and lasting reductions in depression, anxiety and existential distress, and that the effect was linked to the intensity of the experience. Small pilot studies on psilocybin for prolonged grief in bereaved adults began in 2023 and 2024; the early reports are positive but the samples are tiny. Qualitative work consistently describes the same themes our guests describe: a sense of contact or completion with the person lost, grief felt rather than defended against, and a change in how death itself is held. None of this means psilocybin is a treatment for grief, and a retreat is not a trial. Our research review cites the studies.

What the retreat is like when you are grieving

• Preparation. Before you arrive we ask what you are carrying and what you hope for. Guests often bring a photograph or an object; some write a letter. We do not script what will happen in the ceremony, and we are honest that it may not go where you expect.
• Two ceremonies, with a day between. Many grieving guests find the first night is the storm and the second night is the quiet after it. Having both matters.
• Being held. Facilitators stay with the group all night. If you are sobbing at 3 a.m., someone is beside you. Grief in ceremony is expected, not a problem to manage.
• The body. Morning yoga, breathwork and the temazcal give the grief somewhere to go in the body, which is often where it has been stuck.
• Integration. Circles each day, a written guide, and a one-to-one call after you are home. We encourage you to have a grief counsellor, a group or a close friend lined up before you travel.

Screening and who should not come

Everyone completes health and medication screening before any deposit. For grief specifically, we will ask about suicidal thoughts (passive thoughts of not wanting to be here are common in grief and are not automatically a reason to exclude, but active plans are), about alcohol and sleep medication, which often creep up after a loss, and about antidepressants, which are usually compatible but which you must not stop to qualify. A personal or family history of psychosis or bipolar I disorder is a reason not to come. If the loss was by suicide, or you were present at a traumatic death, tell us; it changes how we prepare and may mean we suggest trauma-focused support first. Our screening article covers the detail, and our page on retreats versus clinical care is worth reading before you decide.

Practicalities

The retreat is five days in Playa del Carmen, Mexico, 55 minutes from Cancún airport, for up to eleven guests, at US$1,950 to US$2,300 per person all-inclusive; the retreat page has dates and details. Couples and family members who have lost the same person sometimes come together; the couples page explains how that works. Coming alone is equally common, and the group is small enough that nobody stays a stranger for long.
