In an important step toward medical approval, MDMA, the illegal drug popularly known as Ecstasy or Molly, was shown to bring relief to those suffering from severe post-traumatic stress disorder when paired with talk therapy.
As far as I know, MDMA only became illegal in the summer of 1986. At least that’s what I was told by my dealer. ;-)
Prior to that time it was also used by a number of prison psychiatrists. I heard it was used in the State Prison near Santa Fe, for example, and I was told it made a difference, as it enabled hardened men to speak about their emotions.
