Back to Psychedelic TherapyWhat preparation means
In psychedelic therapy research and licensed services, "preparation" means meetings with trained staff before any session. Most of the sources here are about psilocybin, the natural compound found in certain mushrooms. Psychedelic therapy is still investigational, and nothing here is a recommendation.Evidence label used here: insufficient evidence (too little research to judge). Researcher guidelines are described as guidelines, not as tested results.
What preparation covers in trials
- Part of a larger therapy block. In a psilocybin trial for major depression, supportive psychotherapy totaled about 11 hours across the course. [1]
- Safety rationale. Published safety guidelines for hallucinogen research list careful volunteer preparation and building trust and rapport between monitors and the volunteer before the session among the safeguards. [2] These are guidelines from researchers. They are not proof that preparation, on its own, prevents harm.
How training programs treat it
Colorado's state-approved facilitator training programs must include at least 150 hours of coursework, with Screening at 5 hours and Preparation at 10 hours among the listed topics. [4] That shows regulators regard preparation as a distinct skill. It does not show how well it works.What the evidence says
- Does preparation improve outcomes? Label: insufficient evidence. The FDA states that the contribution of the psychotherapy component to any observed efficacy has not been characterized. [5] Proper evidence not found for a trial that tested preparation separately from the rest of the course. We checked the regulator guidance and a systematic review of psychological interventions in psychedelic research, which found ad hoc and adapted methods rather than a standard one. [6]
- Expectations. Strong expectations can influence results. The FDA suggests trials assess participants' expectations about effects before randomization and at the end of treatment. [5] A review also flags the potential suggestive effects of the information given to patients. [6] Preparation can therefore shape results as well as safety, which is a reason to read trial results with care. See context and expectancy.
What preparation is not
- It is not medical clearance. Only a clinician who knows your history can judge your risks.
- It is not a reason to attempt a similar experience outside a monitored setting. The safeguards described above are tied to settings with trained staff and medical backup.
- It does not remove risk. Trials report adverse events despite preparation. See adverse effects and contraindications.

Frequently asked questions
What happens in a preparation session?
In Oregon's licensed program, it includes intake, review of informed consent and the client bill of rights, accessibility needs, safety and support planning, and transportation planning. [3] Trials differ in length and content. [6]
Does preparation make psychedelic therapy safer?
Researchers list careful preparation among safeguards. [2] No source we read tested preparation by itself, so its separate effect is not known. [5]
Can I follow a preparation guide at home?
This site gives none. The protocols described here run inside supervised programs, and describing them is not a recommendation to use any substance.
Who delivers preparation?
In Oregon, a licensed facilitator. [3]
Where can I get personal advice?
Talk with your own doctor or mental health professional. In the US, call or text 988 in a crisis.

Safety first
What preparation covers in Oregon's licensed program
Preparation is also where eligibility is checked. In Oregon the person decides whether to go ahead, and the facilitator decides whether they can provide services. [3] See screening and eligibility and informed consent.
