Amid a growing global movement toward the decriminalization of psychoactive drugs, a new type of storefront is popping up: the magic mushroom dispensery. These shops sell psilocybin, the active ingredient in mushrooms that change how brain cells work to cause a hallucinogenic experience. Though the sale and possession of mushrooms are still illegal in most jurisdictions, these black-market retailers use loopholes such as religious freedom exemptions, gifting programs and pop-up events to ply their trade. They also operate on the web, where anonymous accounts openly hawk their heavily branded wares.

In the Haight-Ashbury magic mushroom dispensary of San Francisco, a store called Zide Door has reopened after a felony arrest last year for allegedly selling psilocybin without a permit. A supervisor who represents the district blasted police for focusing resources on what he called “a drug bust over substances the city considers of lowest priority.”

From Underground to Mainstream: The Rise of Legal Magic Mushroom Dispensaries

The owners of Canada’s Fun Guyz chain have opened a Winnipeg location, despite the fact that magic mushrooms (psilocybin is the active ingredient in these) are illegal to grow and sell in this country outside certain medical contexts. The owners have billed their new shop as operating as a “medical protest,” and they’re hoping for the same response from local authorities that they’ve already had in Ottawa, Toronto and Vancouver: a police presence to ensure that customers are buying mushrooms safely, and only from legal dispensaries.

As psychedelics move from the margins to the mainstream, more people will likely be searching for ways to buy and consume them legally. Here’s a guide to the best places to get spores and products, as well as some tips for how to avoid getting ripped off by online sellers or even at a physical dispensary.
