STEM Chocolate Bars UK | Safety & Legal Info

Explore STEM chocolate bars at Shroomstore UK. Before browsing, it is critical to understand exactly what these products are and the legal reality in the UK. STEM chocolate bars are chocolate bars infused with psilocybin mushrooms, marketed for microdosing and controlled psychedelic experiences. The brand uses whole P. cubensis fruiting bodies embedded in high-quality chocolate.

In the UK, psilocybin is a Class A controlled substance under the Misuse of Drugs Act 1971. The Drugs Act 2005 explicitly classified “fungus (of any kind) which contains psilocin” as a Class A drug. Possession carries a maximum 7-year sentence; supply carries life imprisonment. UK law enforcement treats psilocybin chocolate as a serious criminal matter—a Liverpool dealer was jailed for over 10 years for selling branded psilocybin chocolate bars.

Note: Some brands using “STEM” or “Stem + Cap” branding sell functional mushroom chocolate containing only Lion’s Mane, Reishi, and Chaga—these are legal. However, STEM-branded psilocybin bars are illegal in the UK.

Shroomstore UK does not sell psilocybin products. This page is informational only. All content is intended for adults aged 18 and over.
