5-MeO-DMT work

Domain VII · Transpersonal, psychedelic & altered states

What it is

"5-MeO-DMT work" is not a single named psychotherapy. It is a cluster of practices around one fast-acting, short-lasting tryptamine: (1) industry-sponsored clinical trials of investigational products in treatment-resistant depression (TRD), and (2) unregulated retreat, ceremonial and private use,…

Format

• Stage D. Preparation. In GH001, preparation was "standard medical care": informed consent, a comfortable dosing environment, and medical and psychological support available throughout. Participants were told they would receive an active tryptamine psychedelic and were given information about…
• Stage E. Dosing day in clinic. Goal: a safe acute experience. Medical staff hold responsibility for monitoring, including continuous remote vital-sign observation and timed checks that are not taken at the peak so as not to disrupt it. Dosing decisions are made by the physicians under the protocol…

Who practises it, and how they are trained or regulated

• Stage A. Pre-screen and referral. Goal: identify possible candidates and rule out obvious exclusions. In the GH001 phase 1/2, this was a telephone suitability screen after recruitment through media, agencies and clinics. Clinician task: discuss trial participation, gather history, refer to the trial site, not to unregulated providers.
• Stage G (outside trials). Harm reduction and integration. For clients who have used or plan to use 5-MeO-DMT in unregulated settings: assessment, risk education in general terms, safety planning, integration of the experience, monitoring for reactivations or lasting difficulties, and referral. Session count: no source; a reasonable frame is 1 to 3 sessions of assessment and education before, and 2 to 6 sessions of…
• Version followed: the regulated clinical-development frame for 5-MeO-DMT (mebufotenin) as published by GH Research / Maastricht University for the investigational product GH001 (phase 1 in healthy volunteers, Reckweg et al. 2021; phase 1/2 in treatment-resistant depression, Reckweg et al. 2023; phase 2b results and FDA status per company release, January 2026), with the atai Beckley BPL-003 phase 2b (company…

Questions to explore with your client

• What drew you to it, and what are you hoping it will change?
• Is there physical contact? Was it explained beforehand, and do you feel free to say no or stop at any point?
• Does it involve any substance, plant preparation, remedy or supplement? Has your doctor or prescriber been told, especially about any medication you take?
• Does it involve intense or unusual breathing? Have you been told about the medical conditions for which that is not advised?
• Does it involve fasting, a special diet or 'detox'? Have you discussed this with your doctor?
• Who runs it, and what training or registration do they hold?
• What actually happens in a session or meeting, and how often?
• What does it cost, and is there pressure to commit to more?
• How do you feel afterwards, in the hours and days that follow?
• Does it fit with, or clash with, the work we do here?

What practitioners of it watch for

• delayed onset of symptoms. Working: stable or improving scores.
• no available support person; plans to use alone. Working: a concrete plan and a booked follow-up.
• abrupt discontinuation, withdrawal, relapse. Working: medication decisions go through the prescriber.
• self-blame, mistrust of all helpers. Working: safety, reduced symptoms, informed choice about reporting.
• waiting for the experience to do the work; wanting repeat use to recapture it. Working: concrete behaviour changes the client can name.

When to involve someone else

• New or worsening physical symptoms, or advice to stop or change prescribed medication: involve the client's doctor or prescriber.
• Signs of coercion, isolation from family and friends, escalating costs or secrecy: discuss openly and consider safeguarding.
• A crisis or thoughts of suicide: follow your crisis protocol. In the US, call or text 988; in the UK and Ireland, Samaritans on 116 123.
