On a sparse stretch of a Vancouver street, an illegal psychedelic drug retailer with a lurid blue and pink fungi motif has opened. Its front windows display a menu of legally dubious offerings: microdoses and high doses of the magic mushroom psilocybin, as well as shroom kits and a variety of other legal but psychedelic drugs. A man claiming to be the store’s spokesman wouldn’t give his name but says he wants the business, FunGuyz, to push for the legalization of psychedelic mushrooms.

CanadaShrooms  and psilocin are psychoactive substances found in various mushrooms that, when eaten, can cause altered perception and sensory hallucinations. They are illegal in Canada under federal criminal law, but possession of certain amounts of psilocybin can be exempted under a ministerial exemption (section 56(1)) or a special access program request.

Shroom Culture: A Closer Look at Psychedelic Experiences in Canada

Last year, a terminal cancer patient named Thomas Hartle received an exemption from Health Canada to use psilocybin in conjunction with psychotherapy to ease his end-of-life anxiety. But Hartle’s exemption expired and his application for another is still pending, so now he’s looking at other ways to get the medicine.

He’s not new to pushing boundaries: Hartle has run illegal weed dispensaries, embarked on a national campaign in 2016 giving out 5 million cannabis seeds and sent grams of psychedelic drugs to Liberal politicians. Now he’s seeking legal avenues for psilocybin, saying it would help more people than psychotherapy alone could. He’s hoping to get a judicial review of the decision, and if that doesn’t work, he’ll try to take his fight all the way to the Supreme Court.
