About the product

On June 27, 2024, Prophet Premium Blends, LLC of Santa Ana, CA, initiated a recall of all flavors of Diamond ShruumzTM brand chocolate bars, cones, and gummies.

Diamond ShruumzTM brand products have been distributed online and at retailers, including those that sell hemp-derived (e.g., cannabidiol [CBD], delta-8 tetrahydrocannabinol [THC]) and smoke/vape products nationwide.

Products containing psychoactive compounds such as cannabis or mushroom extracts are increasing in availability. These "edibles" are often sold as gummy candies, chocolates, or other snack foods. They might contain undisclosed ingredients, including illicit substances, other adulterants, or potentially harmful contaminants that are not approved for use in food.

FDA testing and analysis

As part of this investigation, FDA and state partners have collected multiple samples of Diamond ShruumzTM brand products for testing and analysis.

Additional sample analysis is ongoing, but as of June 25, 2024, FDA test results for two individual chocolate bars have identified the presence of the following:

  • Diamond ShruumzTM Dark Chocolate Bar
    • 4-acetoxy-N,N-dimethyltryptamine (4-acetoxy-DMT, also known as O-acetylpsilocin or psilacetin)
    • desmethoxyyangonin
    • dihydrokavain
    • kavain
  • Diamond ShruumzTM Birthday Cake Chocolate Bar
    • 4-acetoxy-N,N-dimethyltryptamine (4-acetoxy-DMT, also known as O-acetylpsilocin or psilacetin)

There may be variability in test results across products with different formulations as well as potential variability across lots and batches of the same product. Additional testing for the above Diamond ShruumzTM-brand chocolate bars along with testing for other Diamond ShruumzTM-brand products is in progress. FDA and CDC medical officers are interpreting these test results to understand the health risks of ingesting these chemical substances and to determine the appropriate next steps.

Information for clinicians and public health professionals

Clinical effects

Many hallucinogenic mushrooms (also known as "magic mushrooms" or "shrooms") contain psilocybin, a Schedule 1 substance under the Controlled Substances Act that has a high potential for abuse. Psilocybin can temporarily alter a person's mood, thoughts, and perceptions.

Substances such as O-acetylpsilocin (identified during testing of above products), psilocybin, psilocin, dimethyltryptamine (DMT), and lysergic acid diethylamide (LSD) all have similar chemical structures. Individuals who use these substances can experience hallucinations, visual illusions, and other sensory changes. Some patients may have adverse effects such as nausea, vomiting, fast heart rate, anxiety, agitation, lightheadedness, or tremor.

Kava is a plant (Piper methysticum) cultivated in some Pacific Islands. It contains the kavalactones mentioned above (desmethoxyyangonin, dihydrokavain, and kavain) and other compounds. Ingestion of kava can cause numbness of the mouth and skin, loss of coordination, dizziness, and sedation. Ingestion of kava with other substances known to cause sedation, such as benzodiazepines or alcohol, can worsen sedation. Kava can also cause gastrointestinal effects such as nausea and vomiting. Chronic or heavy ingestion of kava has been occasionally associated with certain skin conditions and liver toxicity.


Management of ingestions of these substances is supportive in nature. Patients may require benzodiazepines or other sedative medications for seizures and intravenous fluids or vasopressors for hypotension. Patients with major symptoms of sedation or seizures who are unable to protect their airway may require endotracheal intubation.
