As of October 8, 2026, Amanita muscaria / Muscimol is legal to sell at retail in Washington. Not named on Washington schedules or in any state law; edibles reachable only via general food-adulteration law. Controlling source: RCW 69.50.204.
Verified October 8, 2026 · confidence: confirmedNothing in RCW 69.50.204 (Schedule I) names Amanita muscaria, muscimol, or ibotenic acid (official text fetched 2026-10-07; psilocybin is listed, these are not). A vendor site claims Washington bans Amanita vapes; no statute or rule supporting that was found. No Washington statute or rule names these compounds, so the only reach is general food adulteration law read with FDA's Dec. 18, 2024 determination that A. muscaria and its constituents are unapproved food additives, which does not reach inhaled products such as vapes. Analogue-act reach is remote because muscimol and ibotenic acid are not structurally similar to any Schedule I or II hallucinogen.
Among Washington's 2 neighbors, Idaho and Oregon are legal, the same posture as Washington.
