From what I learned (no personal experiences) the MDMA wouldn't be suitable for any kind of therapy? It makes for few hours of energetic ecstasy followed by few hours of lethargic depression. Without psychedelic effect on patient what is there to work with?
You're probably speaking of an extasy pill (which is often mixed with other stuff etc), not crystallic MDMA. Set and setting does a lot as well. MDMA can be a very powerful psychedelic (personal experience).
