How to be careful with this

Who should be careful, and who should not take it at all

The clearest signal in the research is about psychosis risk. A personal or family history of schizophrenia, bipolar disorder, or other psychotic illness is the strongest reason not to take psilocybin, because it can precipitate an episode. This holds at any dose and it is not something to experiment with privately.

Other situations that warrant a proper conversation with a clinician first include pregnancy and breastfeeding, significant heart conditions, uncontrolled high blood pressure, epilepsy or a seizure history, and any period of acute mental health instability.

Medication interactions worth taking seriously

• Lithium. The combination has been associated with seizures and is widely treated as the most dangerous interaction in this area. Do not combine them.
• MAOIs. Monoamine oxidase inhibitors can substantially and unpredictably intensify effects.
• Tramadol. Lowers the seizure threshold, and combining is not advisable.
• SSRIs and SNRIs. Usually blunt the effect rather than amplify it. The real risk here is a person taking more and more to get through the blunting, then finding it lands all at once.
• Anything serotonergic. Including some migraine medication, some supplements, and other recreational drugs. Stacking serotonergic substances is where genuine danger lives.

This list is not complete, and a pharmacist will check your specific medication without judgement or a written record of why you asked.

If you are microdosing

• Start lower than you think you need, especially with an untested product, and hold it for several sessions before changing anything.
• Do not take a new product for the first time before driving, working with machinery, or anything else where being unexpectedly affected would matter.
• Take it in the morning. Later dosing disrupts sleep for a lot of people, and poor sleep will undo any benefit you were hoping for.
• Keep a simple written log. Memory is a terrible instrument for judging subtle effects, and it flatters whatever you already believe.
• Build in breaks. Continuous daily use is not supported by evidence and tolerance builds quickly.

If you are taking a full dose

• Have a sober person present who knows what you have taken and roughly how much.
• Choose the setting deliberately. Somewhere familiar, private, and free of obligations for the rest of the day.
• Do not drive, and do not plan to make decisions that matter.
• Difficult experiences are usually best handled by changing environment, sitting down, and waiting rather than fighting it. They end.
• Get medical help for a rapidly worsening physical state, a seizure, chest pain, or a person who cannot be kept safe. Tell them what was taken. That information helps far more than it hurts.

The specific risk of untested product

Everything above assumes you know what you took. Frequently you do not. An unlabelled or untested product can be several times stronger than intended, weaker than intended, a different species, or something that is not psilocybin at all. That uncertainty is the entire reason this organization exists, and until testing is routine the safest assumption about any product is that the label might be wrong.

Legal status

Psilocybin remains controlled in most of Canada and the United States, with a patchwork of exemptions, local decriminalisation, and supervised programmes that differ enormously by jurisdiction. Nothing on this site is a suggestion to break the law where you live, and possession consequences are real. Check your own jurisdiction rather than assuming that what is tolerated in one city applies in the next.
