"magic mushroom" edibles in a 2025 Portland study that contained psilocybin

Warnings and recalls

Decode the label

What the ingredients on the package mean, and the ones labs found that weren't on it.

  • Psilocybin / psilocin

    What psilocybin and psilocin are, why psilocin without psilocybin in a gummy is a warning sign, and what tests of retail gummies have found.

  • Amanita muscaria / muscimol

    What muscimol and Amanita muscaria are, what FDA has said about them in food, and why Amanita-labelled gummies often turn out to contain something else.

  • Synthetic tryptamines

    Lab-made psychedelics related to psilocin keep turning up in 'mushroom' gummies. Which ones have been found, where, and what is known about them.

  • Kava (kavalactones)

    Kava is sold openly in gummies, and has also turned up undisclosed in 'mushroom' gummies. What trials found about anxiety, and the liver question.

  • Kratom / mitragynine / 7-OH

    Kratom's best-known alkaloid has been found undisclosed in a 'mushroom' gummy. Why concentrated 7-OH products are different from kratom leaf.

  • THC / cannabinoids

    Undisclosed THC has turned up in 'nootropic' mushroom gummies. Poison-centre data on THC edibles, especially for young children.

  • Proprietary / nootropic mushroom blend

    Lion's mane and reishi aren't psychoactive. But 'nootropic blend' labels have been on gummies that contained psilocin, THC and synthetic tryptamines.

Guides

  • What's actually in mushroom gummies?

    Lab tests of smoke-shop mushroom gummies keep finding ingredients that aren't on the label. Here is what each published test found, and what it can't tell you.

  • How to check a gummy before you take it

    A home reagent test can flag some compounds in a gummy, but not what it is or how much. Here's what Ehrlich reagent shows, what it misses, and what else to check.

  • Do mushroom gummies show up on a drug test?

    Standard workplace panels don't look for psilocin or muscimol. But tested gummies have contained THC, kratom alkaloids and stimulants, and some panels do look for THC.

  • Are mushroom gummies legal?

    Psilocybin is federally controlled, Amanita muscaria isn't, and FDA says Amanita has no place in food. Here's what US federal agencies have said, with dates.

  • What to do if a gummy makes someone sick

    Who to call, what to tell them, and why children are at particular risk. Symptoms reported in mushroom-gummy poisonings, from FDA, CDC and poison-centre data.
