The law, as of November 2, 2026

• Washington. Psilocybin and psilocyn are Schedule I controlled substances.¹ Knowingly possessing them, or using them in public, is a gross misdemeanor: up to 180 days in jail, a fine of up to $1,000, or both, and up to 364 days for someone with two or more prior convictions under that subsection since July 1, 2023. The statute encourages prosecutors to divert these cases.² Making, delivering or possessing them with intent to deliver is a class C felony.³
• Seattle. City Council Resolution 32021, adopted October 4, 2021, says entheogen-related activity "should be among The City of Seattle's lowest enforcement priorities".⁴ A resolution doesn't change the criminal code. Since Ordinance 126896, signed September 20, 2023, Seattle's own code adopts the state possession offense, so possessing psilocybin is a city crime too, with diversion stated as the preferred approach.⁵
• Federal. Psilocybin and psilocyn are in Schedule I.⁶ Simple possession is a federal crime,⁷ and federal law applies everywhere in Washington, including federal land, airports and the mail.
• Mail order. No state allows psilocybin to be sold or sent by mail. Ordering it online is illegal under federal law and in every state.
• Legal access nearby. Oregon and Colorado license supervised psilocybin services for adults 21 and older. In both programs psilocybin is sold only as part of those services, for use in a supervised session, not to take home.⁸⁹

Not legal or medical advice

The almanac reports what statutes, records and studies say, with dates and sources. It can't tell you how the law applies to your situation, and it isn't a substitute for a lawyer or a clinician who knows your circumstances. Laws and programs change; check the date on each entry and the primary sources it links.

We give no dosing, preparation, growing or foraging instructions. Many wild mushrooms in the Pacific Northwest are deadly, and some look like psilocybin species. Never eat a wild mushroom on the strength of a picture or a web page.

If someone needs help

Call 911 in an emergency. For a suspected poisoning, call Poison Control at 1-800-222-1222; from a Washington phone it reaches the Washington Poison Center. For a mental health crisis, call or text 988.

Who publishes the almanac
