A white supremacist took MDMA for a study, and it snapped him out of his beliefs: 'Why am I doing this?'

Right? While it is just one case, I think the reason this occurred was due to the clinical nature of the experience, likely a prior (subconscious) disposition, and a willingness to acquire therapy. But that's the thing, assuming we were able to identify the correct conditions, MDMA is a powerful drug in the sense that it has been observed in creating vastly transformative experiences. In the right hands, it could be a huge step towards treating disorders that plague the deepest, darkest depths of society. The effectiveness would likely also depend on whether or not the patient has had prior experience with the substance. Either way, it warrants more research.
