Belser, Lisa Jerome, Colin Hennigan, Ben Shechet, Scott Hamilton, Berra Yazar-Klosinski, Amy Emerson, and Allison A. Feduccia Journal of Traumatic Stress, 2020, 1-10. Doi : 10.1002/jts.22479 3,4-Methylenedioxymethamphetamine (MDMA)–assisted psychotherapy for posttraumatic stress disorder (PTSD) has been shown to significantly reduce clinical symptomatology, but posttraumatic growth (PTG), which consists of positive changes in self-perception, interpersonal relationships, or philosophy of life, has not been studied with this treatment. Participant data (n = 60) were pooled from three Phase 2 clinical studies employing triple-blind crossover designs. Participants were required to meet DSM-IV-R criteria for [...]

Feduccia, Lisa Jerome, Berra Yazar-Klosinski, Amy Emerson, Michael C. Mithoefer and Rick Doblin Frontiers in Psychiatry, 2019, Volume 10, Article 650. doi: 10.3389/fpsyt.2019.00650 Unsuccessfully treated posttraumatic stress disorder (PTSD) is a serious and lifethreatening disorder. Two medications, paroxetine hydrochloride and sertraline hydrochloride, are approved treatments for PTSD by the Food and Drug Administration (FDA). Analyses of pharmacotherapies for PTSD found only small to moderate effects when compared with placebo. The Multidisciplinary Association for Psychedelic Studies (MAPS) obtained Breakthrough Therapy Designation (BTD) from the FDA for 3,4 methylenedioxymethamphetamine [...]

Preller, Marcus Herdener, Petr Janata and Franz X. Vollenweider Cerebral Cortex, November 2018, 28, 3939–3950. doi : 10.1093/cercor/bhx257 Abstract Classic psychedelic drugs (serotonin 2A, or 5HT2A, receptor agonists) have notable effects on music listening. In the current report, blood oxygen level-dependent (BOLD) signal was collected during music listening in 25 healthy adults after administration of placebo, lysergic acid diethylamide (LSD), and LSD pretreated with the 5HT2A antagonist ketanserin, to investigate the role of 5HT2A receptor signaling in the neural response to the time-varying tonal [...]

Preller, Leonhard Schilbach, Thomas Pokorny, Jan Flemming, Erich Seifritz, and Franz X. Vollenweider The Journal of Neuroscience, 2018, 38, (14), 3603–3611. Doi : 10.1523/JNEUROSCI.1939-17.2018 Distortions of self-experience are critical symptoms of psychiatric disorders and have detrimental effects on social interactions. In light of the immense need for improved and targeted interventions for social impairments, it is important to better understand the neurochemical substrates of social interaction abilities. We therefore investigated the pharmacological and neural correlates of self- and other-initiated social interaction. In [...]

Kuypers Drug Science, Policy and Law, 2020, Volume 6, 1–11. Doi : 10.1177/2050324519900068 Abstract Background : It has been suggested that the outcome of the psychedelic experience is dependent on set and setting. While scientific research into the therapeutic potential of psychedelics is growing, it is clear that in clinical populations an optimal set and setting will not always be attainable. It was aimed to assess under which emotional and environmental circumstances psychedelic users use psychedelics, and the outcome [...]

LSD was used in the treatment of anxiety, depression, psychosomatic diseases and addiction. However, most of the studies were not performed under contemporary standards, and it has taken several decades for a resurgence of interest in LSD research and [...]

Psychedelics are distinctive from other psychoactive drugs in that they alter the mind, whereas opiates or stimulants alter the mood (Meyer & Quenzer, 2013). Psychedelics affect nature of consciousness itself and access otherwise unknown states of consciousness, as opposed to affecting the degree or extent of one's consciousness and inducing proverbial moods such as [...]

Or la recherche scientifique ne dispose pas de données fiables sur les véritables effets de cette substance, ni sur ses risques potentiels. Ursina s’est longtemps refusée à la tentation d’accompagner ses nuits festives de substances chimiques. «J’avais peur du mauvais trip», dit la Zurichoise de 40 ans, casquette et bomber satiné. Jusqu’à ce qu’elle entende parler du LSD en microdose. Elle se procure l’hallucinogène une première fois il y [...]

Entheogens are psychedelic substances which, in adequate dosage under supportive conditions, are known to facilitate visionary, mystical, and/or spiritual experiences. Such substances include psilocybin, peyote, LSD (lysergic acid diethylamide), ibogaine, and ayahuasca. Typically of plant origin, entheogens are [...]
