What's actually in the mushroom gummies sold in shops?

Do mushroom gummies from shops contain psilocybin?

Often they don't, and the label won't tell you what they do contain. In a 2025 study of 12 "magic mushroom" edibles bought at shops in Portland, Oregon, none contained psilocybin, and 8 held ingredients that weren't on the label.¹ Studies in Portland and Virginia found synthetic look-alike drugs, a kratom compound and ephedrine in products sold as mushroom gummies.²³

A gummy that does contain psilocybin is a Schedule I drug that no state lets a shop sell (see the state-by-state rules). Oregon and Colorado test psilocybin, but only products used inside licensed centers. Shop products face no such required testing, and a 2026 CDC report cited "the absence of standardized regulatory oversight for sampling and testing finished products" when it warned of the poisoning risk.⁷

What did lab tests of shop gummies find?

Each of the three published US lab studies of shop edibles we found reported products whose contents didn't match their labels.

The Oregon State University team found psilocin with no psilocybin or related mushroom compounds beside it, and read that as synthetic psilocin added to the candy. One gummy labeled with the Amanita compounds muscarine and muscimol contained neither; another listed a psilocybin amount per piece and had none.¹ The Clinical Toxicology authors called the labeling "overall inaccurate."² The Virginia study began with patients: four adults treated in an emergency department in late 2023, and a 3-year-old hospitalized in June 2024 after eating two gummies.³

We found no published US lab test of "mushroom" capsules bought in shops. For research on capsules sold for microdosing, see microdose dispensaries.

What happened in the Diamond Shruumz outbreak?

In 2024, people across the country became seriously ill after eating Diamond Shruumz-brand chocolate bars, cones and gummies. CDC's June 12, 2024 health alert reported that "several patients required intubation, mechanical ventilation, and admission to an intensive care unit."⁴ The maker recalled every flavor on June 27, 2024.⁵

FDA's final update, with counts as of Oct 31, 2024, reported 180 illnesses in 34 states, with 73 of the 180 people hospitalized. Of the 180, 118 ate Diamond Shruumz products; the other 62 ate mushroom chocolate of another or unknown brand.⁵

FDA's updates called the deaths "potentially associated," and in July 2024 also "under investigation"; it never called one confirmed.⁵ The records we read don't explain the gap, so we give both counts with their dates.

What the April 2026 CDC report found

The report covers 180 cases in 179 people whose illness began between Jan 1 and Oct 11, 2024. Some records were incomplete, so each figure has its own denominator.⁷

Of those with a known age, 81 of 178 (45.5%) were 18 to 29, and 24 of 178 (13.5%) were under 18. Confusion (104 of 157, 66.2%) was the most common sign, and first symptoms began a median of 90 minutes after eating. People who ate only Diamond Shruumz bars had 8.45 times the odds of a seizure of people who ate only other mushroom chocolate.⁷

What did FDA find inside the products?

FDA's National Forensic Chemistry Center tested 54 samples and found five kinds of compounds in shifting mixes: muscimol (an Amanita compound), acetylpsilocin (4-AcO-DMT, a synthetic tryptamine), psilocin, the prescription drug pregabalin, and kavalactones, the active compounds in kava.⁵⁷

Results differed even within one flavor. FDA's summary: "Muscimol does not appear in all products and cannot explain all the symptoms reported."⁵

Are Amanita muscaria gummies legal or safe?

They aren't psilocybin, and FDA says they don't belong in food. Amanita muscaria's active compounds are ibotenic acid, muscimol and muscarine. On Dec 18, 2024, FDA said the mushroom and those compounds are "unapproved food additives" that don't meet the "generally recognized as safe" standard, and that "food containing such ingredients is adulterated." It cited reports of seizures and hospitalizations and recommended that people avoid eating foods with these ingredients.⁸ On Sept 11, 2025, it sent a warning letter to Blue Forest Farms, LLC, finding the company's Amanita "microdose" capsules and tincture to be adulterated supplements and its Amanita chocolate to be adulterated food.⁹

Louisiana's R.S. 40:989.1 lists Amanita muscaria as a hallucinogenic plant: making or distributing a product for human consumption that contains it carries 2 to 10 years and a fine of up to $20,000, and possession up to 5 years, with narrow exceptions such as plants kept for decoration. Act 154 of 2025, in force since Aug 1, 2025, makes it a crime to make, distribute or possess a product for human consumption that contains muscimol, ibotenic acid, phenibut or their analogues; making or distributing one carries 2 to 10 years, a fine of up to $20,000, or both.¹⁰ We found no similar law in another state, though our search may have missed one.

Labels aren't proof either: three Amanita-labeled Portland products had no muscimol, and Amanita-labeled Virginia gummies contained psilocybin or psilocin.¹²³

Are young children eating these products?

More are, by poison center counts. A BMC Public Health study published June 24, 2026 counted 41,612 unintentional recreational drug ingestions by children under 6 reported to US poison centers from 2000 to 2024. The rate involving psilocybin mushrooms and products rose from 0.06 per 100,000 children under 6 in 2018 to 0.94 in 2024.¹¹ The authors caution that processed "mushroom" products are often coded as psilocybin, so some cases may not have involved it, and that psilocybin exposures were less likely to cause a major effect than all other substances combined (relative risk 0.10).¹¹ In the 2024 Virginia report, a 3-year-old who ate two Amanita-labeled gummies was hospitalized.³ If a child may have eaten one, call Poison Control at 1-800-222-1222 right away, even if the child seems fine, and call 911 if the child has collapsed, had a seizure, has trouble breathing or can't be woken.¹⁴

How do Oregon and Colorado test licensed psilocybin?

Both require lab testing before a licensed product reaches a client, and both keep those products inside licensed centers.¹²¹³

Oregon labels must also carry a unique ID number and the psilocybin content those tests found.¹² The Colorado rule we read is the version effective Oct 1, 2024.¹³

How do I read a label or lab report?

A label is a claim. A certificate of analysis (COA), a lab's report on one batch, is evidence only if it's real and matches the package. Check for:

1. A named, accredited lab. Oregon requires ORELAP accreditation; Colorado certifies labs by test category and asks for a lab's ISO 17025 accreditation scope, if it has one. ISO/IEC 17025 is the international standard for testing labs.¹²¹³
2. A lot number that matches the package. A report for another batch says nothing about yours.¹²¹³
3. A test date. Colorado repeats strength testing every nine months.¹³
4. A named method, such as HPLC or LC-MS/MS.¹
5. Psilocybin and psilocin measured by name, ideally with a 4-AcO-DMT screen, as Colorado requires. A single "mushroom extract" figure doesn't show psilocybin content.¹³
6. Contaminants: microbes and heavy metals at least.¹²
7. Pass or fail against stated limits, with the lab's contact details.

A real report covers only the batch tested, and FDA found that samples of one flavor differed.⁵ It also doesn't make a sale legal. We found no published study of the lab reports unlicensed sellers hand out. Our guide to dispensary menus covers the names and claims you'll see.

What should I do if someone gets sick after eating one?

Call Poison Control at 1-800-222-1222; it's free, confidential and open 24/7. Call 911 if the person has collapsed, had a seizure, has trouble breathing or can't be woken.¹⁴ Tell responders the product's name and keep the package to show them. Our help page lists every line.
