[9][10] In addition, the FDA explicitly banned Amanita muscaria ingredients in food products in the United States in late 2024.
[1][7][20] The widespread market availability of Amanita muscaria products, as opposed to hallucinogenic mushrooms in general, is a relatively recent development.
[13] The FDA and other government agencies such as the California Department of Public Health (CDPH) have warned consumers not to buy or eat mushroom edibles.
[4][8] The FDA conducted an investigation and identified ingredients including muscimol, psilacetin, psilocybin, pregabalin, and kava constituents.
[18][21][10] It is unclear exactly why the products caused poisonings, but it may have been related to toxic amounts of muscimol or to presence of ibotenic acid, a known neurotoxin and convulsant.
[6] There is also little quality control in terms of the dosing of mushroom edibles, and amounts of active ingredients may vary considerably even within the same product.
