Brand record
Diamond Shruumz
Every Diamond Shruumz product was recalled in 2024 after a national poisoning outbreak: 180 cases in 34 states, 73 hospitalisations and 2 deaths in CDC's count. Independent testing found psilocin in two of its gummies that did not list it.
The outbreak was mostly linked to Diamond Shruumz 'microdosing' chocolate bars, but the recall covered every flavour of its chocolate bars, cones and gummies. People who became ill reported seizures, loss of consciousness, confusion, agitation, abnormal heart rates and vomiting.
CDC reported that testing of some Diamond Shruumz products found muscimol, psilocin and kavalactones, among other substances, in some but not all products.
Separately, a Virginia poison centre bought two Diamond Shruumz gummy flavours in 2023. Both labels listed an unspecified 'mushroom nootropic', caffeine and functional mushrooms; both contained psilocin.
FDA said in November 2024 that recalled Diamond Shruumz products might still be on some shop shelves. They have a long shelf life.
