How to help someone having a bad trip: when to call 911

If someone near you is in trouble right now, stop reading and call. This page is built emergency-first: the numbers and the signs that mean “call 911” come before everything else. It is a summary of what official Canadian sources say. It is not medical advice, it cannot assess a particular person, and it does not replace emergency services or a doctor.

When should you call 911 for someone having a bad trip?

The most specific official list we found comes from the poison centres. The Canadian Association for Poison Centres and Clinical Toxicology says: if the person is unconscious, not breathing or having a seizure, call 911 (CAPCCT). SickKids, which publishes a poison-centre information page for families, gives the same three signs, worded for a child (SickKids, AboutKidsHealth). Evidence: established as official guidance for poisoning in general. We found no page that applies this list to magic mushrooms in particular.

The Canadian Red Cross First Aid Pocket Guide (2018 edition) gives a different, slightly broader list for poisoning. It says signs of poisoning include vomiting, abdominal pain, an altered level of responsiveness or difficulty breathing. If the person has the last two, it says to call 911; otherwise, it says to call poison control (Canadian Red Cross). “Altered level of responsiveness” is a wider phrase than “unconscious”; the guide does not define it further.

Health Canada adds why a frightening experience can become dangerous. It says a “bad trip” may include paranoia, loss of boundaries and a distorted sense of self, and that impaired judgment “may lead to risk-taking behaviour,” which can lead to traumatic injuries or even death (Health Canada). Among the effects it lists are anxiety and panic attacks, confusion and disorientation, and muscle weakness and twitching, or convulsions (Health Canada).

None of the official pages we opened lists a serious injury, or danger to other people, as a 911 sign for a bad trip. The WorkSafeBC first-aid manual, hosted by St. John Ambulance Canada, says people using hallucinogens, including magic mushrooms, can be dangerous to themselves and others and should be watched closely (WorkSafeBC manual). Beyond the signs above, no source we opened gives a complete checklist for when to call 911. Where the Red Cross list does not apply, its advice is to call poison control.

Calling early matters. A Canadian Centre on Substance Abuse (CCSA) bulletin says the chance of surviving a drug-related poisoning depends partly on how fast the person gets care. It says this holds for all drug poisoning situations, although the bulletin itself focuses on opioids (CCSA, 2017).

What counts as a bad trip?

Health Canada’s page on magic mushrooms says the experience commonly known as a “bad trip” may occur, particularly at high doses, and that it may be frightening (Health Canada). The US National Institute on Drug Abuse describes the same thing as extreme emotions such as fear, confusion or panic (NIDA). Neither page gives a medical definition, and neither tells us how often one needs emergency care. We found no figure in the sources we opened.

The same Health Canada page warns that using magic mushrooms together with substances such as cannabis, amphetamines or alcohol raises the risk of serious side effects (Health Canada). Evidence: established as Health Canada’s position. We give no advice here about taking or withholding anything; ask the poison centre.

Who can you call: 911, the Ontario Poison Centre, 9-8-8?

The poison centres are staffed by registered nurses and pharmacists with specialized training, and they give advice over the phone to anyone of any age who may have been exposed to a poison (CAPCCT). SickKids says the service is free and that poison information centres are open 24 hours a day, 7 days a week (SickKids). The Ontario Poison Centre’s own page confirms the toll-free number and the 24-hour, every-day service (Ontario Poison Centre).

A poison centre is not an ambulance. The poison-centre guidance above says to call 911 for the three signs. For anything short of that, the Red Cross guide says to call poison control (Canadian Red Cross).

9-8-8 is a different service. If the person, or you, is having thoughts of suicide or is in crisis, it offers a call or a text, 24 hours a day, every day of the year (9-8-8). The site describes it as operated by the Public Health Agency of Canada. Evidence: established for what the service offers.

Will you get in trouble for calling 911? What Canada’s Good Samaritan law says

Fear of police is a known reason people do not call. In a 2017 CCSA bulletin that drew on naloxone-programme surveys from 2013 to 2016, the most common reason for not calling 911, given by more than a third of respondents, was concern about police involvement and possible arrest. Those figures come from opioid overdoses, and the bulletin warns they should be read with caution (CCSA, 2017).

Health Canada describes the Good Samaritan Drug Overdose Act as providing some legal protection for people who experience or witness an overdose and call 911 or their local emergency number: from charges of possession of a controlled substance under section 4(1) of the Controlled Drugs and Substances Act, and from breach of conditions about simple possession. It says the protection applies whether the person who seeks help stays or leaves before help arrives. Its page, last modified 27 May 2026, is framed around the opioid crisis and does not mention psychedelics (Health Canada).

What the statute text says about that link. The Good Samaritan Drug Overdose Act is S.C. 2017, c. 4, assented to on 4 May 2017. Justice Laws shows that it amended the Controlled Drugs and Substances Act by adding section 4.1 (Justice Laws, S.C. 2017, c. 4). Section 4.1 itself does not use the name of the Act; its history note cites 2017, c. 4, s. 2 and 2018, c. 16, s. 195.1 (Justice Laws, section 4.1). The wording has changed since 2017. As enacted, the section turned on an “overdose” involving a “controlled substance”. The section now in force, current to 21 September 2026, turns on a “medical emergency” involving a “psychoactive substance”. We found no official explanation of the change and do not guess at one.

In plain terms, as of 4 October 2026, section 4.1 says:

• Who it protects: a person who seeks emergency medical or law enforcement help because they, or another person, are suffering a medical emergency. It also covers anyone at the scene when help arrives, including the person in the emergency.
• What it protects against: being charged or convicted of the simple possession offence in subsection 4(1), if the evidence was obtained or discovered because help was sought or the person stayed at the scene. Subsection 4(1) is the offence of possessing a substance in Schedule I, II or III (Justice Laws, section 4). It also covers charges for breaching pre-trial release or probation conditions that relate to a subsection 4(1) offence.
• What counts as a “medical emergency”: the section defines it as a physiological event induced by a psychoactive substance that results in a life-threatening situation, where there are reasonable grounds to believe the person needs emergency medical or law enforcement help.
• Limits: Health Canada says the Act does not protect against more serious offences, such as outstanding warrants, production and trafficking.

Two points need care. First, the definition requires a “life-threatening situation”. A bad trip that is frightening but not life-threatening is not described anywhere in the section as a medical emergency, and we do not say that the section covers it. Whether a particular situation meets the definition is a legal question we cannot answer. Second, we found no Health Canada or Justice Laws guidance on how the section applies to a psychedelic emergency. For a specific situation, talk to a lawyer. This is not legal advice.

What basic first aid can you verify for someone in distress?

Official Canadian guidance is thin here. Neither Health Canada’s page on magic mushrooms nor the CAMH hallucinogens page contains a step-by-step response for a bad trip. We list below only what we could trace, say whose guidance it is, and say where it comes from a different drug, a different setting or a different country. We have left out any step we could not trace to a source.

Stay calm and stay with them

Health Canada’s page on the Good Samaritan law, which is written about overdose, lists what witnesses should do while waiting: call for emergency help, give first aid including rescue breathing (CPR) if it is needed, and stay calm and reassure the person that help is on the way (Health Canada). CAMH’s page on LSD says people experiencing a dangerous reaction “should be kept as calm as possible,” and that if their distress continues they should receive treatment at a hospital emergency room (CAMH, LSD). That page is about LSD, not psilocybin, so treat it as the nearest Canadian guidance rather than psilocybin-specific advice.

St John Ambulance in the United Kingdom publishes general first-aid advice for drug poisoning that lists stimulants and hallucinogens such as ecstasy and LSD among the causes. For a person who is anxious it says to keep calm, reassure them that the effects will pass, encourage them to breathe slowly and stay with them. If the setting is noisy and the person seems confused, it says to move them to a quiet space. It also says to keep checking breathing, pulse and level of response, and to be ready to start CPR if they become unresponsive (St John Ambulance UK). The emergency numbers on that page are British; in Canada the number is 911. It is not a psilocybin page, and not a Canadian one.

The Canadian Red Cross pocket guide’s general sequence is check, call, care. Its “care” step is to provide care and reassurance, and its call step names 911 or poison control. For a person who is unconscious, is breathing and has no obvious injuries, it says to roll them onto their side and wait for help (Canadian Red Cross). That guide is general first aid, not specific to psychedelics.

What do the sources say about driving?

CAMH says that because LSD profoundly alters perception, driving under its influence is highly hazardous (CAMH, LSD). Health Canada’s psilocybin page, for its part, warns that impaired judgment can lead to risk-taking and serious injury (Health Canada). We found no Health Canada or CAMH sentence about driving on a psilocybin page, so the driving point rests on the LSD page and on that general warning.

What we could not verify: restraint

We found no official Canadian page that gives guidance on physically restraining a person in distress, so we give none.

What if it might not be a mushroom, or the mushroom might be misidentified?

CAMH warns that most of these drugs are illegal and unregulated, and may include toxins or not contain the drug they are sold as. It also warns that hallucinogenic plants can be mistaken for other toxic or lethal plants, for example mushrooms (CAMH, hallucinogens). Health Canada likewise warns that people can consume poisonous mushrooms, mistaking them for magic mushrooms (Health Canada).

The Ontario Poison Centre’s page on mushrooms tells people who have eaten wild mushrooms not to wait until the person feels sick before calling (Ontario Poison Centre). That is the clearest official line for the case where nobody knows what was eaten. We found no page that tells bystanders how to tell the difference between a hard trip and a poisoning.

What about the days after a bad trip?

CAMH’s page on hallucinogens says some people who take them feel depressed or anxious long after, and that rare “flashbacks” can replay the experience days, weeks or even years later (CAMH, hallucinogens). If anyone has thoughts of suicide, 9-8-8 is available by call or text (9-8-8). For questions about distress that lasts, a family doctor or a mental health service is the right place to ask. This site cannot assess anyone.

For the wider picture, see our pages on whether magic mushrooms are safe, whether psilocybin can cause psychosis and whether you can overdose on magic mushrooms.

What is still unknown?

• No official Canadian first-aid protocol for a psilocybin bad trip. The closest are CAMH’s LSD page, Health Canada’s overdose-witness advice and general first-aid guides.
• How often a bad trip needs emergency care. We found no figure in the sources we opened.
• How section 4.1 applies to a psychedelic emergency that is frightening but not clearly life-threatening. That is a question for a lawyer.
• Whether Health Canada, CAMH or the poison centres have psilocybin-specific guidance not yet published on pages we could reach. Check their sites for updates.
