In New Zealand, psilocybin is a Class A controlled drug. Outside approved medical or research settings, possession, use, cultivation and supply can carry serious legal risk. This article is information, not a recommendation.
Why people talk about it
Psilocybin has a long history in cluster headache patient communities. The modern patient-reported history is often traced back to online reports from the late 1990s, which means there is now more than 25 years of patient discussion, case reports, surveys and community documentation.
Many patients report benefit. Some describe it as dramatic, even miraculous. That matters because cluster headache is devastating, and people living with it often reach a point where standard treatment has not worked well enough. It also needs to be held carefully. Patient reports can identify important signals, but they do not remove the need for clinical trials, legal caution and medical advice.
It is not for everyone
Psilocybin may be unsuitable for some people, including people with certain mental health histories, people taking medicines that may interact, people with legal or employment risk, and people who do not feel psychologically safe with altered perception. Effects vary from person to person.
It is also not our place to recommend which treatment path someone should take. Cluster Headache Aotearoa NZ can provide information so that people can ask better questions and make more informed choices about what is right for them.
About dosing information
Clusterbusters publishes its own documentation about approaches patients have used. Their material refers to doses and levels that may be below the classic psychedelic threshold, where the effects may be different from what some people expect from a full psychedelic experience.
We are intentionally not reproducing dosing instructions here. If you read external material, read it in context, understand that effects can still vary, and discuss your situation with your GP or specialist. Be especially cautious around medication interactions, mental health history and legal consequences.
What to discuss with a clinician
- Your diagnosis and whether your attacks are definitely cluster headache.
- Whether evidence-based acute treatments, especially high-flow oxygen and sumatriptan, have been properly tried.
- Whether preventive options such as verapamil or other specialist-led treatments are appropriate.
- Your current medicines and any possible interactions.
- Your mental health history and whether altered perception could be unsafe or distressing for you.
- The legal status of psilocybin in New Zealand.
CHNZ position
We are not anti-psilocybin and we are not here to advocate for illegal use. The honest position is that psilocybin has a substantial patient-reported history in cluster headache, formal research is developing, and legal and medical risks remain real. Always be cautious. Always discuss treatment decisions with your GP or specialist.
