How to Handle a Bad Trip

By Gary Clinton·Addiction specialist·Author of Never Give Up·Updated June 2026 · 6 min read

A bad trip is one of the most frightening experiences a person can have, and the cruellest part is that you can't simply switch it off. With LSD or mushrooms it can run for hours; the fear, the paranoia, the sense that reality has come loose can feel like it will never end. It does end. I want to say that first and clearly, because the single most important thing to hold onto is this: what you are feeling is the drug, it is temporary, and you are not going mad or dying — even when every part of you is convinced otherwise.

First, the one truth to cling to

Almost everything that makes a bad trip terrifying comes from the same root: the fear that it's permanent, that something has broken that won't be put back. It isn't. The chemical wears off, the visions fade, the dread lifts, and your mind returns to itself. If you can plant one flag in the storm, plant this one — "this is the drug, it will pass" — and come back to it again and again.

Grounding: how to bring yourself back

When the fear rises, the instinct is to fight it or run from it, and both make it worse. Grounding works better. It pulls your attention out of the spiralling thoughts and back into your body and the room.

You are not trying to end the trip — you can't, and chasing that makes the fear worse. You are trying to ride it gently until it passes on its own.

If you're the sober friend

If you're looking after someone having a bad trip, you matter more than any technique. Stay calm — your steadiness is contagious, and so is panic. Keep your voice low and warm. Reassure them, over and over, that it's the drug, that it will wear off, and that they're safe. Don't argue with what they're experiencing or try to "snap them out of it"; stay close, keep them from harm, and be the calm anchor in the room. Reduce noise and light. Don't leave them alone, and don't give them more of anything to "level it out".

When to get medical help — don't hesitate

Most bad trips, frightening as they are, are weathered with calm, company and time. But a psychedelic experience can occasionally become a medical situation, and knowing where that line is matters. Ring 999 or 112, or get to an emergency department, if any of these happen:

Please don't let fear of getting in trouble stop you calling. Medics are there to keep people safe, not to judge. A few minutes of embarrassment is nothing against the alternative.

Afterwards — and why it's worth pausing

A bad trip can leave a mark for days or longer: lingering anxiety, low mood, a shaken feeling, sometimes flashbacks. Take that seriously — if it doesn't settle, see your GP, and read my page on HPPD and flashbacks. It's also worth an honest pause. A bad trip is sometimes the mind surfacing something it's been carrying, and if you find yourself frightened, low, or reaching for substances to escape the aftermath, that's exactly the kind of thing it helps to talk through. There's more in my guides to LSD and magic mushrooms, and the door to a confidential conversation is always open.

Frequently asked questions

How do I calm someone down from a bad trip?

Stay calm yourself, move them somewhere quiet and dimly lit, and reassure them gently and repeatedly that it's the drug and it will pass. Don't argue with what they're seeing, don't leave them alone, and don't give them anything more.

When should I call an ambulance during a bad trip?

Call 999 or 112 for chest pain, breathing trouble, a very high temperature, seizures, collapse, violent agitation, or if someone is trying to harm themselves. Also if an unknown substance or dangerous mix is involved. Don't let fear of trouble stop you.

Can a bad trip cause lasting harm?

The trip itself passes, but it can leave lingering anxiety, low mood or flashbacks, and rarely can trigger more serious problems in vulnerable people. If you don't feel right afterwards, see your GP and consider talking it through.
