The police arrived at a suburban home, near Cape Town, in the early hours of a Sunday morning, shortly before Christmas in 2014. They thought they’d stumbled upon a drug den or some kind of sex ring. Instead, they found a odd sort of traditional healer, who looked more like a suburban grandmother than a drug kingpin, and she was minding a group of psychedelic night-trippers. This launched an upcoming bid in the South African courts to have hallucinogenic mushrooms taken off a list of illicit drugs that ranks them alongside heroin, mandrax, and crystal meth.
