A chain that sells illegal hallucinogenic shrooms in Montreal opened a Montreal location this week, risking a police raid and the possible arrest of its employees. The shop, FunGuyz, advertises itself as a “medical dispensary” that sells magic mushrooms, a type of fungi that is considered a hallucinogen. The production, sale and possession of hallucinogens are banned in Canada except for some medical contexts that require special permission from Health Canada. But the people behind FunGuyz say their products should be legalized.

The Montreal branch of FunGuyz sells microdosed capsules and dried mushrooms that contain psilocybin, the psychoactive component in certain types of mushroom. Psilocybin is not yet available legally in any form in Canada, but subtle policy shifts over the past few years have sparked optimism and a raison d’etre among psychedelics enthusiasts who see its eventual legalization as inevitable.

Montreal police on Thursday executed warrants at the store, its third raid in a matter of weeks. Service de police de la Ville de Montreal (SPVM) spokesperson Const. Jeanne Drouin said officers arrested a man and seized drugs at the Ontario St. location, but she did not have details about the man’s condition or whether he had a dog.

While it’s unlikely that anyone will develop a mushroom addiction, repeated consumption can lead to high tolerances and consuming too much can make you very ill. It’s also important to always consume mushrooms under a professional’s supervision because it can take hours for the effects to kick in, and the potential side effects of overdose are life-threatening.
