A clear, honest primer on psilocybin: what it is, what it does, how people take it, what the research actually shows, and how to approach it responsibly. No hype, no exaggerated claims.
Magic mushrooms are fungi that contain psilocybin, a naturally occurring compound the body converts into psilocin, which produces changes in mood, perception, and thought. Most belong to the genus Psilocybe, with Psilocybe cubensis being the most widely grown.
Effects depend heavily on dose, the person, and the setting. A small "microdose" is usually sub-perceptual, while larger doses can produce visuals and intense introspection. They are not considered physically addictive, but they are not right for everyone.
"Magic mushrooms" is an everyday name for mushrooms that contain psilocybin. It is a broad label that covers many different species and product formats.
There are well over a hundred mushroom species known to contain psilocybin, most within the genus Psilocybe. Our guide to what kinds of mushrooms are psychedelic breaks down the main ones. Of these, Psilocybe cubensis is by far the most commonly cultivated, and familiar varieties such as Golden Teacher are all part of that single species. Despite the long lists of "strain" names, the underlying chemistry is similar across most cubensis varieties. Humans have a long relationship with these fungi, as our brief history of our favourite fungi explains.
When you eat psilocybin, your body converts it into psilocin. Psilocin is the compound that actually acts on the brain, mostly by interacting with serotonin receptors. That interaction is what shifts mood, perception, and the sense of time during the experience. You can browse the full shop to see the formats this comes in.
The naturally occurring compound found in the mushroom itself. It is stable, mostly inactive on its own, and acts as the "delivery" form that the body breaks down after you consume it.
What psilocybin becomes once it is metabolised. Psilocin is the active form that engages serotonin receptors in the brain and produces the effects people describe.
There is no single "shroom experience." What you feel depends on the dose, your own body and mindset, and the environment you are in. This is the principle people call "set and setting."
At lower amounts, people often report a lift in mood, more vivid senses, easy laughter, and a feeling of connectedness. At higher amounts, the experience can include visual changes (such as surfaces appearing to move or breathe), altered sense of time, deep introspection, and for some, profound or spiritual feelings. If you are curious about the mechanism, our explainer on what mushrooms do to your brain goes into the serotonin and neuroplasticity science.
Effects typically begin 20 to 60 minutes after eating dried mushrooms and last around 4 to 6 hours, with the strongest part in the middle. Our guide to the 4 phases of a shroom trip walks through what to expect from start to finish. If you are weighing psilocybin against cannabis, the THC vs psilocybin comparison is a useful read.
These ranges are a general reference for dried Psilocybe cubensis, not a prescription. Potency varies between species, batches, and people, so the safest rule is to start low and go slow.
| Tier | Typical range | What people commonly report |
|---|---|---|
| Microdose | 0.05–0.25 g | Sub-perceptual. No visuals. Subtle lift in mood, focus, or presence. The basis of a microdosing routine. |
| Mini | 0.25–0.75 g | Light mood lift, mild body feeling, gentle introspection. Visuals rare or very faint. |
| Museum | 0.5–1.5 g | Noticeable but manageable. Mild visuals, enhanced senses, sociable and creative. Named for being able to walk around a gallery. |
| Moderate | 2–3.5 g | A full recreational dose. Clear visuals, strong introspection, altered sense of time. A clear come-up, peak, and come-down. |
| Mega | 5 g+ | Intense and immersive. Strong visions, possible ego dissolution. For experienced users only, with a sober sitter present. |

The format changes the taste, the onset, and how easy a dose is to measure. Heat breaks down psilocybin, so never cook mushrooms at high temperatures.
The simplest way. Chew thoroughly. Effects usually begin in 30 to 45 minutes, sooner on an emptier stomach. Browse dried mushrooms.
Steep crushed mushrooms in hot (not boiling) water. Easier on the stomach and faster to feel. See our mushroom teas.
Soaking ground mushrooms in lemon juice for about 20 minutes can speed onset and feel stronger. Start with half your usual amount.

Interest in psilocybin's potential has grown quickly, but the science is still early. Here is an honest summary, without overstating it.
Small trials, including work at Johns Hopkins and NYU, found that single supervised doses reduced depression and anxiety for some participants facing serious illness, with effects lasting months. Promising, but preliminary.
An early pilot study of 15 people paired psilocybin with therapy and reported high quit rates at follow-up. The sample was tiny, so larger trials are needed before drawing conclusions.
Early studies have explored psilocybin-assisted therapy for alcohol use disorder and obsessive-compulsive disorder. Results have been encouraging in small groups, but far from settled.
Laboratory and early human research suggests psilocybin may temporarily increase the brain's capacity to form new connections. What that means for everyday outcomes is still being studied.
Most difficult experiences come down to too high a dose, the wrong setting, or the wrong headspace. A little preparation prevents most of them. Our fuller write-ups on advice for taking shrooms and doing shrooms by yourself are worth reading first.
Plan a free day with nowhere to be. Clear your schedule for the next 24 hours and tell someone you trust.
Do not dose if you are in a low or anxious state. Effects amplify whatever you bring in. Consider a microdose instead.
Choose a calm, familiar place. For a first time, have a sober, trusted person with you. Never drive.
Not advised with a personal or family history of psychosis, while pregnant, or alongside certain antidepressants. Never mix with other substances. When unsure, talk to a doctor.
Keep water nearby. Mushrooms can be dehydrating. A sugary drink can help if someone feels overwhelmed.
Never dose because others are pressuring you. If you feel afraid of the effects, that is a good reason to wait.

Being honest matters here. Psilocybin and psilocin are controlled substances under Canada's Controlled Drugs and Substances Act. They are not legally sold for recreational use in Canada.
Limited legal access exists in narrow circumstances, mainly through approved clinical trials and Health Canada's Special Access Program for eligible patients. Laws change and vary by situation, so treat this as general information, not legal advice, and check current rules for your own circumstances.
Psilocybin is not considered physically addictive and does not produce the kind of dependence associated with substances like nicotine or opioids. Tolerance also builds quickly, which naturally discourages frequent use. That said, no substance is right for everyone, and responsible, occasional use is the sensible approach.
Psilocybin has very low physical toxicity, and a life-threatening overdose from the psilocybin itself is extremely unlikely at typical doses. The real risks are psychological, taking too much can lead to an overwhelming experience, and physical, from acting unsafely while impaired. Misidentifying wild mushrooms is far more dangerous than the psilocybin, which is why our guide to mushrooms that cause hallucinations separates myth from fact.
Psilocybin is the stable compound in the mushroom. Once consumed, the body converts it into psilocin, which is the active form that actually produces the effects. In short: psilocybin is what you eat, psilocin is what works.
For dried mushrooms eaten on a fairly empty stomach, effects usually begin within 20 to 60 minutes and last about 4 to 6 hours, with the peak in the middle. Edibles and lemon tek can shift the onset and intensity. Plan for the experience to take most of a day.
Standard workplace drug panels do not typically screen for psilocybin, and it clears the body quickly. Specialised tests can detect it, but they are uncommon. Our drug testing and common questions page covers this in detail. Never rely on this as a guarantee.
Microdosing means taking a very small, sub-perceptual amount, far below a dose that would cause visible effects, on a routine. People do it for subtle shifts in mood, focus, or creativity. Our full What Is Microdosing page covers the terminology and schedules.
