San Diego County's magic mushroom enforcement log, 2020 to 2026

What counts as an entry in this log?

An entry is a public action or health warning by a government agency, dated January 1, 2019 to October 21, 2026, that involves psilocybin, products sold as "magic mushrooms," Amanita products sold as mushrooms, or synthetic look-alikes of psilocin. It has to have happened in San Diego County, or be a statewide warning about a product sold here. Raids, seizures, charges, guilty pleas and warnings all qualify.

We built the list on October 21, 2026 from California Department of Public Health (CDPH) news releases, San Diego County Sheriff's releases, DEA and U.S. Attorney releases, County health advisories and local news archives. Each entry links to an agency document where we could open one. Four of the 14 rest on news reports alone, and the notes column says so. The Sheriff's website refused our automated requests for several releases, so for those entries we relied on agency copies posted elsewhere or on news reports.

What's left out: the County's December 18, 2025 advisory on amatoxin poisoning from foraged wild mushrooms, because it concerns death caps and related species rather than psilocybin products¹¹; research findings; arrests that show up only in jail logs; and cases outside the county. We found no qualifying action from 2019, 2022 or 2023. That's a limit of what agencies announced and what we could find, not proof that nothing happened.

Some entries have no city. The three statewide CDPH warnings don't tie their findings to a city in the county, the Sheriff's October 2024 warning covered purchases made countywide, and reports disagree about where the November 2024 chocolate bar surrender happened: NBC 7 says Vista, while East County Magazine says Chula Vista.¹⁵¹⁶ We couldn't open the Sheriff's own release, so we left that city blank rather than guess.

The log: 14 entries since 2020

The entries run from July 28, 2020 to June 26, 2026. Each one gives the agency, the event type, the product, any published lab finding, a primary link and our notes on conflicts. The list below shows the newest first; the CSV and JSON files below it run oldest first and are free to reuse with credit.

What do the lab results keep finding?

Three brand-name "mushroom" candies in this log have published lab results, and none of those results lists psilocybin, the main drug in magic mushrooms. Two brands tested positive for synthetic tryptamines, lab-made relatives of psilocin. The third contained a mix of compounds, some of them not on the label.¹²⁴

CDPH describes the TRE House findings as "an analogue of psilocin," a DEA Schedule I drug.² PolkaDot's label promised Amanita muscaria; the county lab's reported results named two DET compounds instead. East County Magazine reported Amanita among the findings, which conflicts with the other accounts.¹⁵¹⁶

Outside testing points the same way. A 2025 study in JAMA Network Open bought 12 "magic mushroom" edibles at retail shops in Portland, Oregon, and detected psilocybin in none of them, including one whose label listed a specific psilocybin amount per gummy. It found psilocin in 3 products and the synthetic tryptamines 4-AcO-MiPT and 4-HO-DET in 2.¹²

Raids that turned up mushrooms, including those at Warner Springs in 2021 and at Fallbrook and Bonsall in 2024, were described by agencies as psilocybin cases, but no lab results were published with them.⁷⁸¹⁸ The March 2026 Oceanside seizure described products only as "suspected to contain psilocybin."¹⁰

Which agencies show up, and what does each one do?

The San Diego County Sheriff's Department appears in 11 of the 14 entries. Its Marijuana Enforcement Team led the 2021 Warner Springs warrant and joined the 2026 Oceanside checks. Station crime suppression teams served the 2024 Fallbrook and Bonsall warrants and the 2026 Alpine warrant, and its Narcotics and Gangs Division served the December 2025 Vista warrant alongside CDPH.^710182017 The county's Regional Crime Laboratory tested the PolkaDot bars.¹⁵

CDPH handles product safety. It embargoes adulterated food, which was voluntarily destroyed in the PolkaDot and TRE House cases, and it issues statewide warnings: Diamond Shruumz in June 2024, PolkaDot in November 2024 and TRE House in December 2025.¹²³ FDA and CDC tracked the national Diamond Shruumz outbreak: 180 illnesses in 34 states and 73 hospitalizations through October 31, 2024. FDA counts 3 "potentially associated" deaths; CDC counts 2 "associated" deaths.⁴⁵

The log's one federal prosecution came through DEA and the U.S. Attorney. DEA and the Sheriff's Department investigated the Fallbrook and Bonsall operation, the U.S. Attorney's Office for the Southern District of California charged three North County adults in March 2025, and the third of them pleaded guilty in June 2026.⁸⁹ DEA's Carlsbad office also joined Oceanside police, the Naval Criminal Investigative Service and the Sheriff's team for the March 2026 smoke shop checks.¹⁰

City police appear twice. San Diego and Chula Vista officers assisted the Sheriff's July 2020 sweep of five unlicensed dispensaries, and Oceanside police led the 2026 checks.⁶¹⁰

What does the log mean if you're buying?

Labels aren't a reliable guide. In the three branded cases above, products labeled as mushroom blends or as Amanita held something else, and CDPH's PolkaDot and TRE House warnings applied regardless of lot or date, not to one bad batch.¹²

Smoke shops keep turning up. CDPH says PolkaDot and TRE House products were sold through retailers such as smoke shops, and the 2026 Oceanside and Alpine actions both targeted smoke and vape shops.¹²¹⁰²⁰ In October 2024, reporting on a Sheriff's investigation that included undercover buys of 110 items around the county, Times of San Diego said investigators also found products containing psilocybin mushrooms, which it noted are prohibited for sale throughout the state.¹⁹ Our comparison of what's in the mushroom gummies and chocolates sold in San Diego goes product by product, and our audit of "magic mushrooms for sale in San Diego" listings checks the online sellers.

The actions in this log land on makers, shops and sellers. None of the 14 entries is an action against someone only for buying or holding a small amount, but that reflects what agencies announce, not the law. Possessing psilocybin is a misdemeanor under Health and Safety Code section 11377, punishable by up to a year in county jail, and selling, transporting for sale or giving it away is a felony under section 11379.¹³¹⁴ Our guide to psilocybin penalties in California walks through each statute.

If someone gets sick after eating a mushroom-branded product, call 911 or Poison Control at 1-800-222-1222. To report a product being sold, use CDPH's complaint hotline, (800) 495-3232.³ Parents can find more in our guide to mushroom edibles for parents.

What has changed in this log?

October 21, 2026. Published with 14 entries, July 28, 2020 to June 26, 2026. We left the city blank on the November 8, 2024 PolkaDot surrender because reports conflict (Vista or Chula Vista). We listed the June 26, 2026 guilty plea in the Fallbrook case as a charge; the U.S. Attorney's release set sentencing dates in July, August and September, and we found no sentencing announcement as of today.⁹ We left out the County's December 18, 2025 wild mushroom advisory as out of scope.

When we update the log, we recheck the same agency newsrooms and add a dated line here. If you know of an action we missed, or a source that settles the Vista and Chula Vista question, tell us. Corrections follow our editorial standards.
