Toadstools and Toxins
October 5, 2026 at 10:37PMWhen Eric Leas, a public-health scientist, discovered packages of “magic mushroom” gummies for sale in a smoke shop, he wondered: Were these candies even legal? Had they been properly tested, and did anyone actually know what constituted a safe dose? This Aeon piece follows Leas down a rabbit hole as he investigates whether the Amanita muscaria products currently on store shelves are as safe as their candy-like packaging suggests.
I found a product with a very high reported amount of muscimol. It was a gummy product, one in a benign-looking package that did not have childproofing or clear warnings. I began doing the calculation no one wants to do. If a young child ate the entire package, mistaking it for candy, could they die? I took the reported amount of muscimol, the toxicology estimates (the LD50), a conversion used to translate dosing between species, and the average weight of a small child. The result looked bad. Bad enough that I did not quite trust myself. So, I called a friend, Matthieu Rouffet, a medicinal chemist and the dean of science at a local college, who does toxicology calculations more often than I do. I wanted him to tell me I had made an error. Instead, he was alarmed too.
