My guess is that there is not a one size fits all cure for PTSD and that there probably never will be. I'm all for continuing research and for having good tools in our tool boxes when needed. Probably a combination of tools is best.
I personally don't trust what I read on this MAPS site. Maybe MDMA will help some people some of the time. But whenever I hear something touted as a miracle drug, I tend to walk the other way.

Just my opinion,
