Key points
- If someone is unconscious, having a seizure, struggling to breathe or has chest pain, call 911.
- For advice, call Poison Help at 1-800-222-1222 and tell them the product name. FDA advises this for people who become ill after eating mushroom edibles.
- Children can mistake these products for sweets. Poison-centre reports of young children eating edibles have risen sharply.
Emergency
If someone can’t be woken, is having a seizure, is struggling to breathe or has chest pain, call 911 now.
Who should you call?
Poison Help: 1-800-222-1222. FDA tells anyone who becomes ill after eating Diamond Shruumz products to contact a healthcare provider or this line and say what they ate. It also asks healthcare providers to report these illnesses (FDA, 2024). The same applies to any gummy: give the brand, product name and flavour, and the label if you have it.
What symptoms have been reported?
In the Diamond Shruumz outbreak, people reported seizures, central nervous system depression (loss of consciousness, confusion, sleepiness), agitation, abnormal heart rates, high or low blood pressure, nausea and vomiting (FDA, 2024). Of 180 cases, 73 people were hospitalised, 38 needed intensive care and 29 needed a breathing tube (Rumph et al., 2026).
Patients seen by a Virginia poison centre after eating Amanita-labelled gummies had a fast heart rate, confusion, anxiety or sleepiness, and nausea. All four adults were discharged from the emergency department within 12 hours (Michienzi et al., 2024).
Germany’s risk-assessment agency reports that muscimol gummies have caused impaired consciousness up to coma, confusion and agitation. Effects usually start about 30 minutes after eating and generally wear off within 24 hours, but can last longer after large amounts (BfR).
Why are children at particular risk?
Gummies look like sweets. A 3-year-old in Virginia was hospitalised after eating two Amanita-labelled gummies (Michienzi et al., 2024). US poison-centre reports of children under 6 eating cannabis edibles rose from 207 in 2017 to 3,054 in 2021, and 22.7% were admitted to hospital (Tweet et al., 2023). In 2021–2022, 30% of poison-centre cases involving delta-8 and related THC products were children under 6 (Burgess et al., 2024). California warned that TRE House products may be particularly dangerous for young children, who could mistake them for ordinary candy (CDPH, 2025).
Store these products out of sight and reach of children, in their original packaging. If a child might have eaten one, call Poison Help even if they seem fine.
How do you report a product?
Healthcare providers can report illnesses to their local health department or Poison Help (FDA, 2024). If you find a recalled product still for sale, FDA asks you to report the retailer (FDA, 2024). In California, the CDPH complaint hotline is (800) 495-3232 (CDPH, 2025).

Blue Ridge Poison Center (Virginia) managed five people evaluated after eating gummies labelled as containing Amanita muscaria (Sept 2023–June 2024), including a 3-year-old who was hospitalised. Investigators bought six packages of five brands from gas stations and smoke shops; four of six contained unlabelled psilocybin or psilocin, with caffeine, ephedrine, mitragynine (kratom) and DMT among other unlabelled findings.
- German Federal Institute for Risk Assessment (BfR). Fly agaric poison: health risks of 'fruit gummies' containing muscimol – children are particularly at risk.
BfR reports poisonings from muscimol gummies reported by German poison centres, including impaired consciousness up to coma, confusion and agitation. Ibotenic acid converts to muscimol on drying and heating; effects usually begin about 30 minutes after eating and generally wear off within 24 hours, longer after large amounts. Children may mistake the products for sweets.
