I said potential to help cure. I think MDMA assisted psychotherapy, in particular, has the potential to cure PTSD in a lot of people. Not everyone. But a lot.
And the patent issue on this has been solved by starting a non-profit pharmaceutical company and getting grants and donations to fund these trials. And then patenting the treatment protocols under a public trust corp I believe. I follow MAPS quite a bit, the non-profit that spear headed a lot of this.
I think what the other poster said about the FDA approving drugs with more cardiovascular issues than MDMA is true and points towards corporate bias in the panel (which most of us probably know is true).
Treating mental health with SSRIs etc. is a big business. Some of that panel probably stands to lose money if some of those repeat customers find a cure.
