I'm amazed they manage to write this article without mentioning Nixon's "most dangerous man in America", Timothy Leary... who apparently pre-dates William Richards in the therapeutic study of psychedelics. Garcia-Romeu described the model in simple terms: “Basically you give someone a really high dose and they have a really transformative experience. And you’ve prepared them for that and then after the fact, you help them integrate it and they get on with their lives.” This sounds pretty much like a re-run of the 1961 Concord Prison Experiment (but with hopefully fewer methodology issues). There's a big question mark over Leary's science in my mind, but he's a fascinating character and would add a ton of colour to this kind of story.
