The California Department of Public Health warned on December 11, 2025 not to eat specific TRE House Magic Mushroom gummies, chocolate bars, and syrup after laboratory testing found 4-AcO-DET and, in most products, 4-AcO-DMT. The July 1, 2026 ACS Laboratory certificates published by TRE House report 4-AcO-DET and 4-AcO-DMT below the limit of quantification (<LOQ) for the Strawberry Dream, Watermelon Wonder, Sour Tropical, and Blue Raspberry batches, which are the samples ACS tested. CDPH’s warning names Strawberry Dream, Watermelon Wonder, and Sour Tropical gummies, not Blue Raspberry; it applies to the listed products regardless of lot number or package date.

What was the TRE House warning?
California’s Department of Public Health warning, release NR25-024, named TRE House brand Magic Mushroom gummies, chocolate bars, and syrup. CDPH said its laboratory-tested products contained 4-Acetoxy-DET and that most also contained 4-Acetoxy-DMT, which it described as illegal psychedelic compounds.
CDPH said the products were labeled with “Magic Mushroom Microdose Blend” and “Proprietary Nootropic Mushroom Blend.” The agency warned that its notice applied to the listed products regardless of lot number or package date.
Which products and UPCs did CDPH name?
| Product named by CDPH | Size | UPC |
|---|---|---|
| Chocolate Bar Peanut Butter | 1.76 oz | 810135374439 |
| Chocolate Bar Chocolate Milk | 1.76 oz | 810135370004 |
| Chocolate Bar Fruity Cereal | 1.76 oz | 810135370035 |
| Gummies Watermelon Wonder | 2.12 oz | 810135370158 |
| Gummies Sour Tropical | 2.12 oz | 810135374552 |
| Gummies Strawberry Dream | 2.12 oz | 810135370127 |
| Syrup Strawberry Gelato | 4 oz | 810135376082 |
CDPH said these items had been sold online and through retailers including smoke shops. It also said it was investigating TRE House and its contract manufacturers; more than 1,000 pounds of TRE House gummies were embargoed and later voluntarily destroyed.
What are 4-AcO-DET and 4-AcO-DMT?
CDPH said the products were found to contain an analogue of psilocin, a DEA schedule I drug, and described both 4-AcO-DET and 4-AcO-DMT as illegal psychedelics. The warning named the products and UPCs listed above and applied regardless of lot numbers or date information.
The broader category can be confusing because laboratory terms identify distinct compounds. This explainer on thc metabolites and active compounds explains why a laboratory name should not be treated as a catch-all label.
What do the newer TRE House gummy certificates report?
TRE House publishes product reports and says every product is backed by a Certificate of Analysis. Its four July 1, 2026 ACS Laboratory certificates below identify the product, batch, and result for 4-AcO-DET and 4-AcO-DMT.
| Gummy flavor | Batch | Lab and certificate date | 4-AcO-DET | 4-AcO-DMT |
|---|---|---|---|---|
| Strawberry Dream certificate | THMG-SD128 | ACS Laboratory, July 1, 2026 | <LOQ | <LOQ |
| Watermelon Wonder certificate | THMG-WW128 | ACS Laboratory, July 1, 2026 | <LOQ | <LOQ |
| Sour Tropical certificate | THMG-ST128 | ACS Laboratory, July 1, 2026 | <LOQ | <LOQ |
| Blue Raspberry certificate | THMG-BR128 | ACS Laboratory, July 1, 2026 | <LOQ | <LOQ |
“<LOQ” means the reported result was below the laboratory’s limit of quantification: the method did not report an amount it could quantify at or above that threshold. The certificates apply to the sample ACS Laboratory analyzed, so the useful comparison is the flavor and batch on your package against the flavor and batch on its certificate.
Batch-specific results matter. In a separate investigation of another mushroom-edible brand, the CDC’s Diamond Shruumz investigation noted that results can vary among formulations and among lots of the same product.
What does TRE House say its mushroom gummies contain?
TRE House markets its gummies as a proprietary natural mushroom blend. Its mushroom-gummy collection says the gummies do not contain psilocybin, psilocin, psilacetin (4-AcO-DMT), 4-hydroxy-DET, 4-Acetoxy-DET, or amanita muscaria.
For a separate question about THC testing, see THC drug testing and detection. That topic is different from the compounds named in CDPH’s TRE House warning.
How can you check a TRE House gummy batch?
Start with the product name and batch number printed on the package. Then open TRE House’s lab reports, choose the matching flavor, and compare the batch identifier and certificate date with the package in hand. The July certificates above are for Extra Strength Strawberry Dream batch THMG-SD128, Watermelon Wonder batch THMG-WW128, Sour Tropical batch THMG-ST128, and Blue Raspberry batch THMG-BR128.
If the package is one of the products and UPCs in CDPH’s December 2025 warning, the warning says it applies regardless of the lot number. If you experience ill effects after consuming a product, CDPH directs consumers to consult a health care provider.
Before you order or use a package you already have
- Match the exact product and UPC against CDPH’s warning list.
- Match the flavor and batch number to the corresponding certificate, rather than relying on a report for a different flavor or batch.
- For shipping, TRE House says its online orders require age verification and that state restrictions apply, including a restriction on all products shipped to California.
- If a package or report does not give you enough information to make your decision, contact TRE House support through its contact page before proceeding.
