You missed my point: In the use of MDMA, is there a downside to misdiagnosis? Let's say MDMA was effective treating alcoholism, but had no therapeutic effect, nor any harmful effect, on anyone else. Lots of people take it recreationally. We can certainly find out if that population is suffering any negative consequences.

I take your point about the dubiousness of some parts of the DSM. But what's your theory about sociopaths? Are you seriously suggesting sociopathy will be redeemed in some way?
