First LSD Study in 35 Years Treats Last Subject:

Dear xxxx,
Summer is fast approaching. The days are getting longer, the breeze is getting warmer, and the only thing that’s growing faster than the roses in my garden is MAPS’ clinical research program.In the past month, new studies of MDMA-assisted psychotherapy for PTSD were approved by government agencies in both Israel and the United States. We also finalized the data for our Swiss study of MDMA-assisted psychotherapy for PTSD, Health Canada completed its inspection of our Vancouver study facilities, and we began planning for a study of ibogaine treatment for addiction in New Zealand.

MAPS is now planning or conducting research in six countries and on four continents. As a worldwide leader in psychedelic psychotherapy research, we have a responsibility to ensure the clarity, consistency, and reliability of our treatment approach.

Setting standards for treatment, developing training manuals, and making research tools accessible to researchers around the world are all part of how MAPS is helping bring psychedelic healing to those who need it most.

On May 26, the last subject was treated in our Swiss study of LSD-assisted psychotherapy for anxiety due to life-threatening illness—the first clinical LSD study in over 35 years.

Psychiatrist and lead investigator Peter Gasser, M.D., indicated in a letter to friends and colleagues that he was deeply moved by the changes he witnessed in his subjects after undergoing treatment with LSD-assisted psychotherapy. He believes that the treatment helped some of them overcome the sense of isolation and despair that often comes with confronting death.

One subject reported that she wanted to clap “the warm buttocks of a cow” once more before she died as a symbol of reconnecting to something solid, familiar, and full of life. “In the second LSD session, she was dancing and singing in the treatment room, something she always wanted to do but never dared to do in her whole life.”

It’s still too early to report the final results of this study, but the fact that not a single subject had a serious negative reaction to the treatment is a major accomplishment that opens the door to future LSD psychotherapy research.

In this edition of the MAPS E-mail Newsletter, learn how we’re expanding our research program, internationalizing our efforts, and planning for the future of psychedelic medicine.

None of our accomplishments would have been possible without our members. We need your support more than ever.
