How to Stop a Bad Trip: What Actually Works
To stop a bad trip: change environment and music first, then diazepam 10 to 20 mg if needed. What works, what doesn't, and when to call 911.

If you or someone near you is having a bad trip, the fastest effective intervention is changing the environment. Go outside. Change the music. Move somewhere quieter. If that is not enough and you have a benzodiazepine, diazepam 10 to 20 mg orally will blunt the experience within 30 to 60 minutes.
One situation skips all of that. If the person is on lithium and took LSD or psilocybin, call emergency services now. That combination carries a real seizure risk and is not something to sit with.
Which of the three situations is this
The response should match what is actually happening, so start by sorting it.
Uncomfortable but manageable. This is most bad trips. Anxiety, paranoia, loops of intrusive thought, a sense of dread or unreality. The person is oriented, talking, and not in physical danger. Environment and grounding do their best work here.
Acute psychological crisis. Extreme terror, ego dissolution that is not integrating, sustained inability to recognize reality, or behavior suggesting they might hurt themselves. Calm one-on-one support, possibly a benzo, possibly a crisis line.
Medical emergency. Call 911.
- Seizures, any convulsive episode, even a brief one
- Loss of consciousness or inability to rouse them
- Hyperthermia: skin extremely hot and dry rather than sweaty, confusion, especially with MDMA, stimulants or hot weather in the mix. More on risk factors in our LSD guide
- Lithium known or suspected, with LSD or psilocybin
- Sustained extreme agitation that cannot be managed safely
- Suspected NBOMe or another adulterant. NBOMes sold as LSD cause seizures, cardiovascular events and hyperthermia at doses that present as a strong trip. A blotter with no taste at all, or a bitter chemical taste, is a reason to suspect one
- Other seizure-threshold combinations, notably tramadol, or high-dose stimulants
- Behavior that puts the person or anyone else in physical danger
Start with the room
For anything short of a medical emergency, this is where to begin. The evidence here is clinical consensus and psychedelic therapy protocol rather than trial data (Tier 9, expert consensus with substantial clinical experience behind it), but the mechanisms are understood and none of it can hurt.
Change the physical environment. The most effective thing you can do without a drug. Go outside, move to a room with different lighting. Environment is not background during a psychedelic experience, it is part of the experience. A loud, crowded festival stage will sustain a bad trip; a quiet room with soft light very often shifts it.
Change the music. Psychedelic therapists find consistently that music steers emotional content. If the current track is dark, ominous or fast, change it or kill it. Calm, wordless, gentle: ambient, nature sounds, classical.
One calm sober person, not a crowd. Being alone amplifies fear, but so does a ring of worried friends hovering, which reads as confirmation that something is badly wrong. One grounded person who is not panicking, who does not need to say much, is among the most reliable interventions there is.
Ground through the senses. The 5-4-3-2-1 technique: name 5 things you can see, 4 you can touch and describe by texture, 3 you can hear, 2 you can smell, 1 you can taste. It anchors attention in present sensory reality and interrupts the recursive loop. It sounds too simple to work. It works.
Say that it will pass. The most destabilizing part of a bad trip is usually the conviction that this state is permanent. Calm, repeated, factual reassurance goes straight at that: “you took this, it has a known duration, it will end, you are physically safe.” The MAPS therapy protocols formalize the same idea as trust, let go, be open.
Move the body. A walk, a change of position, holding something cold or warm. Engaging the body interrupts loops that are purely mental.
And do not fight it. Trying to force the state to stop amplifies the anxiety. Surrender rather than resistance is the standard therapeutic instruction because it is what works, though it is far easier said than done mid-crisis, which is exactly why the sober presence and the room matter so much.
If that is not enough: benzodiazepines
Benzos are the pharmacological first choice. No formal RCT has tested benzodiazepines specifically for bad trips, so this rests on their known mechanism plus clinical experience in psychedelic therapy settings, but it is the standard recommendation in every harm reduction and therapy context.
They potentiate GABA-A receptors, enhancing the brain’s main inhibitory system. Psychedelics act through 5-HT2A agonism, and benzos do not block that receptor, which is why they blunt the experience without ending it. The anxiolytic, sedative and muscle-relaxant effects cut the distress; the visual and perceptual changes may partly continue.
- Diazepam (Valium) is the one most likely to be available at a party. 10 to 20 mg orally, onset 30 to 60 minutes. Long half-life, so sedation can carry into the next day. Do not drive.
- Lorazepam (Ativan) is faster, 20 to 40 minutes, at comparable effect. 1 to 2 mg is a reasonable start.
- Alprazolam (Xanax) is fast but short. It works, and the shorter window means it may need redosing, which raises the over-sedation risk if anything else is on board.
Start at the low end and wait the full onset before considering more. Do not combine with alcohol, GHB, ketamine or opioids; stacking CNS depressants at a festival is how people stop breathing. Keep a heavily sedated person upright or in the recovery position. The goal is calm and safety, not unconsciousness.
Do not give antipsychotics
This is a real harm reduction concern, not a theoretical one. Haloperidol, olanzapine and similar drugs get reached for by medical staff unfamiliar with psychedelic pharmacology, and there are four problems with that.
- They can make the distress worse. Dopamine blockade produces its own dissociation and depersonalization, which intensifies the frightening parts rather than relieving them.
- Extrapyramidal side effects are terrifying mid-trip. Dystonia, akathisia, and the rigid zombie sedation can feel catastrophic to someone already frightened.
- They lower the seizure threshold, in a setting where adulterants, drug combinations and dehydration have already raised the risk.
- They do not do the useful thing. GABA potentiation is directly suited to acute distress. Dopamine blockade is not.
If festival medical staff reach for an antipsychotic, you can ask for a benzodiazepine instead and say why.
The lithium exception, in detail
The LSD-lithium and psilocybin-lithium combinations carry significantly elevated seizure risk, not just an intensified trip. A Johns Hopkins analysis of experience reports and a 2024 case report both document seizures in this combination, including in people with no prior seizure history. The mechanism is not settled, but lithium’s narrow therapeutic window and its effects on ion channels that interact with serotonergic activity are the likely route.
Do not wait to see whether benzos help. Do not try to manage it with the lights and the music. Call emergency services and tell them exactly what was taken.
If you do not know whether someone is on lithium, ask. If they are worrying you and you know they take prescription medication for a mood disorder, “are you on lithium?” is a fair question in this context.
Someone to call at 3am
If you are struggling and there is no trusted person with you:
Fireside Project, call or text 62-FIRESIDE (623-473-7433). A free psychedelic peer support line staffed by trained volunteers, daily 3pm to 3am PT with extended weekend hours. They are trained specifically for difficult psychedelic experiences and will not send emergency services unless there is genuine physical risk.
Zendo Project (zendoproject.org). MAPS-affiliated, trains volunteers for festival settings and runs in-person safe spaces at major events. If you are at a festival, look for their tent. Their four principles: create a safe space, sit with rather than guide, difficult is not the same as bad, trust the process.
If a friend is spinning out at 3am, calling Fireside is often a better first move than the festival medical tent, where staff may have no psychedelic-specific training and where the medical setting itself can escalate the fear.
