The short answer
What do sources say a guide or sitter does, and does having one change anything?
Sources describe a calm presence that makes sure the person feels safe and comfortable and mostly does not steer the experience. Metanoia's search on 7 November 2026 located no controlled or prospective study comparing sessions with and without a guide in healthy adults, so none can say whether the role changes outcomes in healthy adults. One survey of people who chose to describe a hard mushroom experience compared those who had a guide with those who did not, and found an association with a shorter hard phase. This card is not a standard of care.
What do research and rules report?
- What a provider survey reports. Of 80 respondents who sit with clients, 76.3% chose the statement that they make sure clients feel safe and comfortable but otherwise do not interfere, 66.3% chose responding encouragingly without trying to guide, and 31.3% chose actively discussing issues clients raise during the session. More than one answer could be chosen. The question concerned a session in general, not a moment of distress. The 107 practitioners came from advertisements, mailing lists and social media, and their answers could not be verified. Source 1, level 1
- What one state requires. In Oregon's licensed psilocybin program, a facilitator must be present throughout an administration session and monitor clients in person by sight and sound for physical or emotional distress, with video not sufficient. A facilitator may not engage in conduct needing another license, such as diagnosing or treating, with a narrow exception for notified licensed professionals in preparation and integration sessions (OAR 333-333-5130(5) and (6)), and must attempt contact with each client within 72 hours. This is the text in force on 7 November 2026, and it applies in that program only. A new Oregon rulemaking with a planned effective date of 15 January 2027 may change it. Source 2, level 1
- What laboratory and expert sources describe. The 2008 laboratory guidelines, which are expert opinion, describe two facilitators so the participant is never alone, and calm reassurance. Source 3, level 1 A 2025 consensus of 89 experts listed 30 items trials should report, including who was present. It says what to report, not what to do. Source 4, level 1
- What was measured. In a 2016 survey of 1,993 adults describing their hardest mushroom experience, a guide's presence went with a shorter hard phase but not a lower degree of difficulty. The sample chose to report a hard experience. Source 5, level 1
- In 20 analyzed adults with diagnosed depression in one trial, a stronger participant-rated alliance with facilitators went with lower depression scores later. This is correlation in a small group and says nothing about healthy adults. Source 6, level 1
What is not known?
“Not located” means that the searches Metanoia ran on 7 November 2026 did not return it. They covered PubMed, Europe PMC including preprint servers, and ClinicalTrials.gov. Two further papers found by a review on 8 November 2026 were read in full and are used below. Other papers named in that review, on silence in sessions and on facilitator competencies, have not been read and carry no claim. More searching could change the picture.
- Whether a guide's presence changes outcomes in healthy adults. Not located.
- Which tasks matter, such as silence, touch or conversation. The searches did not locate a study in healthy adults that compares such tasks against each other or tests which of them matter. One 2026 interview study of 18 participants in a psilocybin trial for generalized anxiety disorder describes how they experienced protocol-defined supportive touch, and it did not compare touch with other tasks. Source 7, level 1
- How much facilitators shape the acute experience in healthy volunteers. Two 2026 studies bear on this, but only abstracts were accessible, so neither is used.
- Who sits in unregulated settings, and how they are trained. Who sits in unregulated settings is not described beyond the one self-selected survey above. On training, one 2026 analysis interviewed representatives of 13 United States facilitation training programs. It describes programs that differ widely in length, content and certification, says it is not a representative survey, and notes that what graduates go on to do is not generally known.

What this card does not say
- It does not recommend having or not having a guide, or any way to guide.
- It does not say what to do or when to seek help in a hard moment. For what sources report on hard moments, see the card When a session gets hard.
- Metanoia does not train, certify, supervise or supply guides.
- Sessions taken alone, at home or by video, and one state's rules on presence, are on the card alone, at home, or remotely.
- It does not rate how risky, safe or worthwhile any practice is.

Where does this come from?
Grade key: 1 = peer-reviewed publication, official document or primary record. 2 = reliable secondary source. 3 = grey source (community, social media, organization pages). 4 = traditional or ethnographic source. A grade names the type of source, and the design and limits are given in the text. “Full text” means Metanoia read the body of the paper in full on the date given, and any part not read is named. A source read only in part carries no claim on this card. Sources described in the text as found and not read carry no claim and are not listed.
