Medical Advisory Board

  • George R. Greer, M.D.

    Dr. George R. Greer is the Board Chair, former Medical Director and a Co-Founder of the Heffter Research Institute. During the Institute’s 28-year history, he supervised the scientific review of all of Heffter’s research studies into the mechanisms of action and clinical applications of MDMA, psilocybin and other classic psychedelic drugs. To date, almost 150 peer-reviewed scientific publications have resulted from Heffter’s financial support.

    The most significant projects wholly funded by Heffter have been all three studies of psilocybin-assisted psychotherapy for depression and anxiety in cancer patients. Those projects led to the Usona Institute receiving FDA Breakthrough Therapy designation of psilocybin treatment for Major Depression. Usona is now in the final research stages to gain FDA approval of psilocybin for that medical indication.

    Heffter’s current primary research focus is psilocybin-assisted therapy for addictions. Two pilot studies in the treatment of Alcohol and Tobacco Use Disorders have been published, and placebo-controlled clinical trials for those are in their final stages at Johns Hopkins University and New York University, respectively.

    Heffter is currently funding two studies of psilocybin for the treatment of Opioid Use Disorder at the University of Wisconsin and a study of LSD for opioid abuse in patients with chronic back pain at Johns Hopkins. It has helped fund the current placebo-controlled clinical trial of psilocybin for cocaine addiction at the University of Alabama, Birmingham, and is in the planning stages for a study at the University of New Mexico of psilocybin treatment for methamphetamine addiction, which is growing.

    In addition to those addiction-related projects, Heffter has also been funding research at Yale University on psilocybin treatment for Major Depression, Obsessive-Compulsive Disorder and Cluster Headache, and for depressed terminally ill patients in palliative care at the Dana Farber Cancer Institute of Harvard University.

    Heffter has spent almost $15 million in its entire history funding research, including virtually all of the psilocybin research in the US and much of the psilocybin research in Switzerland, all through private donations. At this stage, psychedelic treatment research cannot progress without major support from the National Institutes of Health, which has expressed interest in such research in a recent Congressional hearing.

    In addition to his role at Heffter, Dr. Greer conducted around 100 MDMA-assisted therapeutic sessions when MDMA was a legal adjunct to psychotherapy circa 1980, and published the first group study of the therapeutic use of that drug.

    Dr. Greer is a Distinguished Life Fellow of the American Psychiatric Association and Past President of the Psychiatric Medical Association of New Mexico, serving as its Legislative Representative for several years. He was also the Clinical Director of Mental Health Services for the New Mexico Corrections Department during the 1990s.
