The short answer
What do helpers do when someone is overwhelmed in a session, and does it work?
Sources describe staying calm, offering reassurance, grounding such as holding a hand when this was explained in advance, and changing the music or the room. Metanoia located no controlled comparison of these, so none can be called best. In a 2016 survey of people who reported a bad trip with mushrooms, 39% ranked it among the five hardest experiences of their lives and 2.7% sought medical help. These numbers describe people who answered or called, not all users. This card is not a protocol. In a US medical emergency the number is 911, and the 988 Suicide and Crisis Lifeline takes calls and texts.
What do people in the field say?
Reported practice, not a recommendation. This marking applies to everything in this section.
Method note. Metanoia collected these questions and descriptions from public community posts and organization pages on 3 November 2026 (10 items on difficulty and crisis in the moment). It is one collection in one session. It is not a sample of the field, and the count says nothing about how common anything is. The accounts were not checked against research. Level 3 names a type of source and does not rank its quality. Nothing is quoted and no person or organization is named.
- Finding out before reacting. Posts describe asking what the substance was, when it was taken, what medicines are involved and who the person is. They separate a state that puts the body at risk from an emotional or spiritual one.
- Talking or not talking. One approach is described as bringing the person down. Another is a calm, matter-of-fact tone with encouragement to breathe and relax. Some preparation tells participants in advance to surrender to the experience.
- Grounding and changing the surroundings. People describe bare feet on the floor, eye contact, a hand on the belly, a song, a heavy blanket, a change of music, a change of room, holding hands, touch with consent, and a quiet, warm and safe space.
- Other participants. Posts describe moving away someone who cannot give support and explaining what is happening to volunteers.
Questions about medicines in a crisis belong to a separate topic that is still in preparation. Nothing on this card addresses them.
What does research know?
Most of this comes from surveys of people who reported a hard experience, a telephone line, one Oregon cohort and old laboratory guidelines. Each source describes who took part, and none gives the rate of hard moments among all users.
How common are hard moments, and how long do they last?
- In an online survey of 1,993 people who reported a “bad trip” with mushrooms (recruited in 2013 in user forums, 78% men and 89% white), 39% ranked it among the five most difficult experiences of their lives. 10.7% put themselves or others at risk of physical harm, 2.6% acted with physical violence and 2.7% sought medical help. Of 1,339 whose experience was more than a year earlier, 7.6% sought treatment for psychological symptoms they linked to it. The authors describe three cases of lasting psychotic symptoms and three suicide attempts. 84% said they benefited from the hard experience. The authors stress that the sample is people who chose to report a hard experience, so the frequency cannot be estimated. Source 3, level 1, 2016
- The hard part lasted an hour or less for 31%, one to two hours for 25% and two hours or more for 40%. A longer hard phase went with a higher degree of difficulty, and with less lasting meaning and well-being. Source 3, level 1, 2016
- In the 2017 Global Drug Survey, 19 of 9,233 mushroom users in the past year who answered (0.2%) sought urgent medical treatment. The authors estimate 0.06% of uses, about one in 1,800. The only predictor found was younger age. Symptoms were anxiety or panic (68%), paranoia (68%), seeing or hearing things (42%) and loss of consciousness (37%). 8 of the 19 were admitted to hospital. Of 18 who gave a recovery time, 12 were back to normal within 6 hours and one was not within 24 hours (back within 5 to 7 days). Reasons the respondents gave were mood (47%), mixing substances (37%), place (37%) and having taken too much (26%). Source 8, level 1, 2022
- A US peer-support telephone line logged 25,419 interactions between April 2021 and February 2026. 40.2% were sorted as support during an active trip, 32.1% as integration and 11.6% as out of scope, including medical emergencies referred on to 911 or 988. Among callers about psilocybin, 42.2% reported distress, and distress was reported in about 47% of active-trip calls and 36% of integration calls. Referrals to emergency services were 0.28% of psilocybin calls (26 of 9,348), 0.36% for LSD, 0.44% for MDMA, 0.65% for cannabis and 0.08% for ketamine. Where the phase was known (6,388 callers), 43.9% were after the peak, 33.3% at the peak and 22.8% coming up. 66.3% were alone. The authors stress that the data reflect who chose to call and not how common distress is. Source 5, level 1, 2026
- In the first pilot of that line (April 2021 to September 2022), calls were about fear, anxiety, confusion and feeling overwhelmed (3,386 callers). 39.9% of 1,630 callers who were in the middle of an experience were alone, and 27.4% mentioned a background psychiatric condition, as reported by volunteers and not by clinicians. Source 4, level 1, 2023
- In the Oregon cohort of 346 participants, four serious behavioral reactions were reported over three months (1.2%), all among people with no earlier experience of psychedelics who had asked for the service for mental health problems. One involved violent behavior and being taken to hospital during the session. In the other three, participants themselves reported, one week to three months later, a visit to an emergency department and a new medicine. Facilitators reported only one of the four. 1.6% said the experience harmed them (at one week) and 88.8% said they felt safe during it. The authors note that the cohort is about 5% of recipients and that the state's required behavioral report covers three days only. Source 6, level 1, 2026
- The 2008 Johns Hopkins guidelines (expert opinion) say the most common risk is overwhelming distress while the substance is acting, which could lead to risky behavior such as leaving the place. Without screening and preparation, fear and paranoia may come before aggression toward oneself or others. The authors say such cases are rare and ask readers not to form an unrealistic picture. They report that among 54 volunteers at a high dose in their laboratory, reassurance was enough in every case of acute distress. Source 2, level 1, 2008
- In its discussion the 2016 survey adds that, in the same group's laboratory, about 250 volunteers in more than 380 sessions were not harmed, and that three confusion events that could have been dangerous (0.9%) led to a change in the way sessions were run. Source 3, level 1, 2016
What do helpers do, as described?
Reported practice, not a recommendation. This marking applies to everything in this section.
The items below describe what guidelines, rules and surveys say. They are not an operating protocol and not a recommendation. Metanoia located no study that compares them with one another (see “What is not known”).
Research safety guidelines, 2008
- These guidelines are expert opinion for high-dose laboratory studies with trained monitors. They describe the accepted first response to an outbreak of anxiety as strong personal support and reassurance: conveying safety and calm, empathizing with the intensity, and reminding the participant that they are in a study, took a substance and will return to ordinary awareness in minutes or hours. Source 2, level 1, 2008
- They say that trying to talk a participant down with techniques that redefine reality may be counterproductive and make things worse, citing a 1977 paper. Instead the participant is reminded to surrender to the experience. Source 2, level 1, 2008
- They describe interpersonal grounding, such as holding the participant's hand, when the practice was explained in advance. Preparation also covers how to meet a hard experience, for example moving toward a frightening image instead of away from it. Source 2, level 1, 2008
- They describe at least two monitors, so that the participant is never alone and one monitor is always in the room, and a physician available at every session. Source 2, level 1, 2008
- For the room they describe comfortable furniture without sharp objects, no phone, a check that nobody can leave through a window, an escort to the bathroom with a door that does not lock, and preventing anyone from leaving the site. Participants whose eyes are covered are checked on from time to time, for example by asking them to say where they are. Source 2, level 1, 2008
- Limits: the document dates from 2008, concerns laboratory studies at a high dose with trained monitors, and has no controlled evidence comparing techniques. Its section on drug treatment in a crisis was read and is not covered here. Source 2, level 1, 2008
What Oregon requires facilitators to be trained in
- The core skills module includes responding to psychological distress, creating a safe space for hard emotional experiences, appropriate intervention and when a higher level of care is needed, and recognizing unwanted behavioral and medical reactions. The administration module includes challenging behaviors (unexpected disclosures, substance-induced psychosis, suicidal thoughts), trauma during a session, and safety and emergency response protocols. The safety and ethics module includes harm reduction, de-escalation and conflict resolution. The preparation module includes spotting safety concerns and setting a client-led safety plan. This lists training topics. It is not an operating protocol. The version read carries a change note of 1 January 2024 and may not be current. Source 1, level 1, rule text
What people in a survey said they tried
- Among people who had a hard experience, 91% tried to end it, 69% tried to calm the mind, 63% changed place, and between 33% and 40% moved the body, changed the music or the social setting, or asked a friend for help. The central finding is that every strategy helped only modestly: across strategies, the share who said one helped a lot averaged 57% of the share who tried it. The survey also reports strategies that involve substances, which are not covered here. Source 3, level 1, 2016
Who is on site
- Of 49 retreat organizations, 20 (40.8%) reported a licensed health professional present for part of the retreat. 32 (65.3%) reported trained staff on site at least sometimes, meaning a health professional or staff trained in emergency response. Two religious organizations relied only on sober volunteers. 29 (59.2%) said facilitators use the substance in ceremonies, and 4 of them made clear that someone sober is always present. The authors note that roles and responsibilities are not always clear, and that a facilitator's own use may hamper a response to an emergency when no other sober person is there. The study does not test whether any practice relates to outcomes. Source 7, level 1, 2026
- A US peer-support line uses trained volunteers (50 hours of training per volunteer in the pilot), anonymity, and calls or messages. The techniques used are recorded on a form, but the paper does not report them. Sources 4, 5, level 1, 2023 and 2026
- In interviews with 13 US training programs, “appropriate emergency response” and “safety” were among the practical topics the programs raised. The authors note that counting mentions does not give the share of programs that teach them. Source 9, level 1, 2026
What was measured about benefit?
- Of 848 people who answered a survey after calling the line (20.9% answered), 65.9% said the call calmed them from distress. Asked what they would have done without it, 12.5% said they might have called 911, 10.8% said they would have gone to an emergency department and 29.3% said they might have been harmed. This is self-report with no control group. Source 4, level 1, 2023
- Of 2,777 callers (10.9% answered), 76.1% strongly agreed that they felt supported and 3.2% disagreed that they did. Differences between volunteers were described and not tested. This measures satisfaction. It does not measure outcome. Source 5, level 1, 2026
- In the 2016 survey, having a guide present went with a shorter hard phase. It did not go with a lower degree of difficulty. A comfortable setting and social support went with less physical risk (odds ratios 0.56 and 0.66, meaning lower odds of physical risk). These are correlations in a survey of people who had a hard experience, and they do not show cause. Source 3, level 1, 2016
- In the Johns Hopkins laboratory, reassurance was enough in every acute-distress case among 54 volunteers, as the authors report. There is no comparison group. Source 2, level 1, 2008
- On the hard experience itself, 84% of the 2016 survey said they benefited, and the authors add that difficult experiences are not necessary for a positive outcome. 8% reported a decrease in well-being. This was measured in one defined group, people who reported a hard experience, and it is not a promise. Source 3, level 1, 2016
What is not known?
“Not located” means that the searches Metanoia ran on 3 November 2026 did not return it. They covered PubMed (eleven search strings), Europe PMC including preprint servers, and ClinicalTrials.gov. More searching could change the picture.
- A controlled comparison of ways to respond in the moment (grounding, changing the music, touch, talking, silence). Not located in PubMed, in ClinicalTrials.gov (no records) or in the first 15 of 56 preprint results scanned.
- Whether a guide's training or the type of response changes the outcome. Not located. Two abstracts report differences between guides in how much they explain, and Metanoia has not read them in full, so it makes no claim from them.
- How often a crisis happens in regulated services outside Oregon. Not located.
- Which techniques helpers used on the support line. They are recorded on a form and are not reported in the paper.
- How common distress is among all users. Every source read describes people who had a hard experience, called a line or sought care. Two of the papers say so plainly (3, 5).
- How long difficulties last after a session. That is a separate topic, still in preparation.
- Medicines in a crisis. That is a separate topic, still in preparation. Two reviews on it were found and not read.
What do traditions do?
Reported practice, not a recommendation. This marking applies to everything in this section.
Read in part, for direction only. This section rests on one paper on one Zapotec community in Oaxaca (30 interviews), which Metanoia read in part. It carries no claim and it does not stand for Zapotec practice or for any tradition. Interviewees said that people ask a companion to stay in another room and watch over them, mainly so that they do not leave the house, which the community sees as the worst outcome. The companion remembers what was said during the experience to help with interpretation. Frightening visions are read as a sign of something evil and are not read as a positive message, and some people decide not to take the mushrooms again. The paper records no evidence on whether any of this works (10, level 4, 2025).
The 2008 Johns Hopkins authors write that Indigenous cultures limit use to ritual settings with guidance, and that these cultures should not be seen as a perfect model for clinical use. This is expert opinion. It is not an ethnographic description (2, level 1, 2008).
What this card does not say
- It does not name a technique that works. No controlled comparison was located.
- It does not say what to do in any situation, and nothing on it is an instruction.
- It does not address medicines in a crisis.
- It does not say that people should avoid medical help, and the figures on emergency referrals are not advice to call or not to call.
- Rates here belong to people who reported, called or sought care. They are not rates among all users.
