Mystery 'Magic' Chocolate Bars Pose Serious Health Risks

In January 2026, Denver investigators became suspicious of PolkaDot-branded chocolate bars sold alongside energy shots and nicotine pouches. This suspicion was fueled by an earlier warning from California public health officials. California authorities destroyed more than US$3 million worth of these chocolate bars after laboratory tests revealed the presence of added synthetic psychoactive drugs.

These PolkaDot products, resembling everyday candy, were deceptively marketed as containing non-hallucinogenic mushroom blends. However, laboratory tests confirmed the presence of psilocybin, psilocin, and synthetic tryptamines. Denver health department investigators found these bars and gummies from six retailers contained illegal psychoactive ingredients.

The composition of PolkaDot products can vary significantly across the U.S. because there isn't a single regulated manufacturer. Instead, multiple entities can purchase packaging kits and fill them with various compounds. This allows the products to easily slip into local stores and evade federal detection.

Colorado's 2022 Natural Medicine Act decriminalized personal possession and cultivation of certain natural psychedelic substances, but it did not authorize over-the-counter retail sales. Consumers often mistakenly believe that because Colorado has decriminalized 'magic mushrooms,' any mushroom product is legal to buy, which is not the case.

Public health officials are emphasizing consumer education and retailer outreach. Advisories urge residents to avoid purchasing PolkaDot products and to report sightings. Businesses selling unlawful products face severe penalties, including fines and license suspension or revocation. Retailers are being coached on basic due diligence, such as verifying the legitimacy of wholesalers and product disclosures.
