What Should You Do If Someone Has a Bad Reaction (“Bad Trip”) to Psilocybin Mushrooms? A Guide for Australians

A “bad trip” is a term used to describe a distressing or frightening reaction to a psychedelic drug. This can involve intense fear, anxiety, paranoia, confusion, and a feeling of losing control. Psilocybin mushrooms are illegal for general use in Australia, and a bad reaction in an unregulated setting is a serious medical and psychological emergency. This guide provides practical, evidence-based steps to manage the situation and outlines when to seek urgent professional help.

Immediate Steps to Take

If someone is having a bad reaction, your immediate priority is to ensure their safety and remain calm. The Support, Prompt, Assist, Reassure (SPAR) method provides a simple framework.

1. Assess the Situation

First, check for any immediate physical danger. Ensure the person is not at risk of harming themselves or others. If they are in a stressful or chaotic environment, try to move them to a quieter, calmer space if it is safe to do so. Try to determine what substance they have taken, the dose, and when they took it. This information will be vital if they need medical attention. Also, look out for signs of a physical emergency, such as severe vomiting, loss of consciousness, or seizures. If you observe any of these, call emergency services immediately.

2. Be a Calm and Supportive Presence

Your reaction can influence theirs. Stay calm and speak in a low, soothing voice. Let them know that they are safe and that you are there to help. Remind them that the effects are temporary and will eventually end. Reassurance is incredibly powerful.

3. Help Them Change Their Focus (Grounding Techniques)

If someone is having a frightening experience, they may be stuck in a loop of anxious thoughts. Grounding techniques can be very effective in these situations. You can try the “5-4-3-2-1” method to help them focus on the present moment. Ask them to name five things they can see, four things they can touch, three things they can hear, two things they can smell, and one thing they can taste. Or, simply encourage them to focus on their breathing, taking slow, deep breaths.

4. Use the SPAR Approach

• Support: Offer a reassuring physical presence. Sit with them calmly.
• Prompt: Gently prompt them to talk about what they are experiencing. Listen without judgment.
• Assist: If they want a drink of water, get it for them. Do not leave them alone.
• Reassure: Continuously reassure them that the feelings will pass and that they are safe.

What to Avoid

• Do Not Argue or Challenge Their Experience: The person is in a highly altered state, and their reality is real to them. Arguing can escalate fear and distress.
• Do Not Use Physical Restraints: Unless they are an immediate danger to themselves or others, do not restrain them. This can cause panic and injury.
• Do Not Leave Them Alone: A bad trip can be terrifying, and the person should not be left alone.
• Avoid Overstimulation: Turn off loud music, bright lights, and remove any other potential triggers. Create a quiet, peaceful atmosphere.

When to Call for Emergency Help (000)

In Australia, a bad reaction to psilocybin mushrooms is a medical emergency, and you should not hesitate to call 000 if you are concerned.

Do not wait—call for help immediately if you observe any of the following:

• Loss of consciousness or unresponsiveness.
• Severe agitation or aggression that makes the person a danger to themselves or others.
• Seizures.
• Severe vomiting or signs of physical distress.
• Extreme confusion that persists or worsens.
• Signs of serotonin toxicity, such as high fever, excessive sweating, or muscle rigidity.
• Any physical health emergency, such as chest pain or difficulty breathing.

What to Tell the Operator:
When you call, stay calm and provide the operator with clear information. Clearly state that you need an ambulance. Tell the operator the person’s approximate age, what you believe they have taken, and the symptoms they are experiencing. Let them know the address as clearly as possible. Follow any instructions the operator gives you. The operator may give you specific first-aid instructions while you wait for the ambulance.

What Happens at the Hospital?

Emergency department staff are trained to manage drug-related emergencies. Do not be afraid of legal consequences; the priority is the person’s health.

De-escalation: Medical staff will try to calm the person down in a safe, supportive environment.
Medical Treatment: They will monitor vital signs and provide supportive care. This may include intravenous fluids and, in some cases, medications such as benzodiazepines to manage severe anxiety, agitation, or seizures.
Blood Tests: Blood tests may be taken to check for other substances or underlying issues.
Observation: The person will be monitored until the acute effects have subsided.

Legal Considerations

Psilocybin is illegal for general use in Australia. However, in a medical emergency, the law prioritises saving a life. Do not delay calling for help out of fear of legal consequences.

Conclusion

A bad reaction to psilocybin mushrooms is a serious event that requires a calm and measured response.
