Not medical advice

This site summarizes published research, drug labels and public records. It can't account for your health, your medicines or your history, and it isn't a substitute for a doctor, pharmacist or other clinician. Don't start, stop or change a prescribed medicine because of something you read here; talk to your prescriber first.

In an emergency, call 911. For crisis support, call or text 988. Poison Control: 1-800-222-1222. More on our help page.

Not dosing advice

We don't recommend amounts, schedules or methods, and nothing here should be read as a suggested amount. Where a page reports an amount, it's what a study measured or what trial participants received. The calculators in our audit are described, not endorsed, and we don't record their outputs. Psilocybin content varies between mushrooms, so no page or calculator can know what's in yours (see the potency data).

Legal status in the US

• Federal law: psilocybin and psilocin are Schedule I controlled substances.¹
• Oregon and Colorado run state-regulated programs in which adults take psilocybin with a licensed facilitator: at licensed service centers in Oregon, and at licensed healing centers or other approved locations in Colorado.²³⁴ Oregon's program covers psilocybin services at licensed service centers; it doesn't make buying psilocybin anywhere else legal.² Colorado law also lets adults 21 and over possess, use and share natural medicine for personal use without payment, but selling it outside the licensed system is illegal.⁵ Federal law still applies in both states.
• Cities that have deprioritized enforcement haven't made psilocybin legal. It remains illegal under federal law there.
• Ordering psilocybin online or by mail is illegal under federal law and in every state, including Oregon and Colorado.

Laws change, and this summary isn't legal advice. Check the current law where you live.

Limits of what we report

We check facts against primary sources and date every page, but research moves and we can make mistakes. Most studies we cite are small, and many involve screened volunteers in supervised settings or self-selected survey respondents, so their results may not apply to you. Product labels and lab results describe the samples tested, not every batch. If you spot an error, please tell us.
