On June 12, 2024, the Center for Disease Control and Prevention (CDC), Food and Drug Administration (FDA), and America’s Poison Centers warned consumers not to buy or consume Diamond Shruumz chocolate bars, cones, and gummies. The agencies are investigating reports of illness from consumers, including nausea, vomiting, low and high blood pressure, and seizures, after ingesting Diamond Shruumz chocolate bars, cones, and gummies. Twelve illnesses, including 10 hospitalizations with several requiring intubation or admission to an intensive care unit, have been reported in eight states throughout the U.S. The cause of illness remains unknown.

Diamond Shruumz products are labeled as containing a proprietary blend of mushrooms such as reishi and lion’s mane, are promoted to provide an “experience” of “pleasure” and “peace of mind.” They are sold nationwide through the company’s website as well as other online retailers and shops that typically sell hemp-derived (e.g., cannabidiol [CBD], delta-8 tetrahydrocannabinol [THC]) and smoke/vape products.

(See ConsumerLab’s Reviews of Lion’s Mane and Chaga Supplements and Reishi Mushroom Supplements for our Top Picks among these products.)

The CDC has advised consumers to discard and destroy any product. The agency also warned consumers not to consume any products claiming to produce feelings of euphoria, hallucinations, or psychedelic effects and to store edibles and other products that contain mushrooms, THC, or CBD safely away from children as they may mistake some edibles for candy.

The CDC, FDA, and Poison Centers are continuing to monitor reports of illness nationwide. Consumers experiencing adverse effects after ingesting Diamond Shruumz brand products should seek immediate help and report the effects to the Poison Help Line at 1-800-222-1222.
