MAPS (the Multidisciplinary Association for Psychedelic Studies) is a non-profit research and educational organization that develops medical, legal, and cultural contexts for people to benefit from the careful uses of psychedelics and marijuana. They have been able to fund clinical trials using substances such as MDMDA for treatment resistant PTSD, LSD assisted psychotherapy, ayahuasca-assisted treatment for drug addiction and other modalities of therapy. Founder of MAPS, Rick Doblin is interviewed on London Real and covers the interesting struggles of maintaining support for the healing potential of MDMA despite government agencies ignoring their own recommendations.
Healing Trauma in Veterans with MDMA-Assisted Psychotherapy. MAPS clinical trials with MDMA were showing results where greater than 75% of study participants no longer qualified for PTSD after an extended period after the 2-3 sessions with MDMA assisted psychotherapy. This is after initially having treatment resistant PTSD to be eligible to enter the study.

From Reset.me: When 65-year-old Estalyn Walcoff took psilocybin, the active ingredient in psychedelic “magic” mushrooms, her worst fears and pains came up to the surface. Then, they transformed into a profound “feeling of connectedness that runs through all of us,” she said in a video.
Transpersonal psychology is a school of psychology that integrates the spiritual and transcendent aspects of the human experience with the framework of modern psychology.
One Proponent of this branch of psychology is Stan Grof whose writings cover a vast range of topics within the various realms of experience. Grof operates with a cartography consisting of three kinds of territories: the realm of the sensory barrier and the personal unconscious (described by psychoanalysis), the perinatal or birth-related realm (organizing principles for the psyche), and the transpersonal realm. According to this view proper engagement with the first two realms sets the stage for an ascent to the third, transpersonal, realm. His early therapy, and research, was carried out with the aid of psychedelic substances such as lysergic acid diethylamide (LSD), psilocybin, mescaline, dipropyl-tryptamine (DPT), and methylene-dioxy-amphetamine (MDA). Later, when LSD was prohibited, Grof developed other methods of therapy, such as holotropic breathwork.
