Symposium: Opening Up – Shaping the future: therapeutic applications of MDMA

This symposium discusses research into the therapeutic use of MDMA, both historically and presently. In the period following its rediscovery in the 1970s, MDMA soon gained a reputation as a powerful adjunct for psychotherapy. In 1985 in the US (and 1988 in the Netherlands), MDMA was scheduled as a controlled substance, effectively stemming all research and most therapeutic use.
Since the mid 2000s, research and clinical interest into the therapeutic potential of MDMA has increased significantly and MDMA-assisted psychotherapy is on track to become a licensed treatment in several years. What do we know about the therapeutic use of this substance? Who may benefit from treatment, and what would such treatment look like? How can MDMA-assisted psychotherapy be integrated into mental health care? These questions, and others, will be addressed by several international experts in the field.
