The group behind the push to make MDMA a legal therapy is a group called maps, the guy behind it is a new age nut job. He's a disciple of a discredited quack doctor named Stanislav Grof who's own wife was institutionalized after he gave her too much lsd.
The guy is a nut, and he has written about everything from past life regression, to alien abduction. And his group is the one writing the protocols that doctors who perform this mdma therapy will have to carry out. It's insane. I am amazed at the progress they have been able to make through the fda, and it's entirely because of slick political lobbying and outright skewing of statistical data to get the desired results.
I spent a lot of time reading about the background of the group but I am too exhausted and depressed to retype it all here, but suffice it to say, this is a bunch of burning man new age whackos masquerading their pseudo spiritual wares as some kind of new breakthrough therapy... for example, if a patient has a weird trip, and becomes delusional on a psychedelic, thinks they see Jesus... the therapist is supposed to encourage them to think they had a real spiritual experience. That's that kind of crap that I think could be more damaging than good. If someone has a hallucination on a psychedelic, the therapist should be there to explain that no, they didn't really see Jesus... but this new kind of therapy would encourage the patient to think they did, it's insane.
The whole theory behind this kind of therapy, is that mental illness doesn't really exist... that people become mentally ill when they are having a "spiritual crisis" (the guy behind this therapy has written entire books about this nonsense). He believes thst encouraging people to have such spiritual experiences under the infouence of psychedelics will cure them of their mental illness. When drugs were made illegal in the 70s he came up with this kind of therapy around "breathwork" but it was basically a self induced kind of hyperventilating. The therapy was discredited and he was forced to stop practicing... now his students are back with this latest rendition of his brand of "therapy", and they are pushing mdma and mushrooms as the drug of choice.
