As of October 8, 2026, Amanita muscaria / Muscimol is legal to sell at retail in Pennsylvania. Not named on Pennsylvania schedules or in any state law; edibles reachable only via general food-adulteration law. Controlling source: Controlled Substance, Drug, Device and Cosmetic Act, 1972 Act 64 (full text PDF).
Verified October 8, 2026 · confidence: confirmedNothing in 35 P.S. Sec. 780-104 (Controlled Substance, Drug, Device and Cosmetic Act Sec. 4) names Amanita muscaria, muscimol, or ibotenic acid (official text fetched 2026-10-07; psilocybin is listed, these are not). Pennsylvania's Department of Health can add substances by regulation (28 Pa. Code Sec. 25.72); none naming these compounds surfaced. No Pennsylvania 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 Pennsylvania's 6 neighbors, Delaware, Maryland, New Jersey, New York, Ohio and West Virginia are legal, the same posture as Pennsylvania.
