A systematic study of microdosing psychedelics RESEARCH ARTICLE Vince Polito, Richard J. Stevenson PLoS ONE, 2019, 14, (2), e0211023. Doi : 10.1371/journal.pone.0211023 Abstract The phenomenon of ‘microdosing’, that is, regular ingestion of very small quantities of psychedelic substances, has seen a rapid explosion of popularity in recent years. Individuals who microdose report minimal acute effects from these substances yet claim a range of long-term general health and wellbeing benefits. There have been no published empirical studies of microdosing and the current legal and bureaucratic climate makes direct empirical investigation of the effects of psychedelics difficult. In Study One we conducted a systematic, observational investigation of individuals [...]

Hendricks Journal of Drug Issues, 2019, 1–12 Doi : 10.1177/0022042619871008 Abstract Microdosing classic psychedelics (e.g., LSD [lysergic acid diethylamide] and psilocybin) is the practice of taking small amounts of these substances to bring about various positive life changes. Little is known about the subjective experiences and perceptions of those who engage in the practice. Accordingly, we use the sociology of accounts as a theoretical framework to explore the ways that those who microdose excuse or justify their practice. Using data from semistructured interviews with 30 people who had microdosed, [...]

ISERSON Cambridge Quarterly of Healthcare Ethics, 2019, 28, 168–177. © Cambridge University Press 2018. doi : 10.1017/S0963180118000518 Abstract : The available treatments for disorders affecting large segments of the population are often costly, complex, and only marginally effective, and many have numerous side effects. These disorders include dementias, debilitating neurological disorders, the multiple types of drug addiction, and the spectrum of mental health disorders. Preliminary studies have shown that a variety of psychedelic and similar U.S. Drug Enforcement Administration Schedule I drugs may offer better treatment options than those that currently exist and pose potentially [...]

Doi : 10.1556/2054.2018.002 Background and aims : Psychedelic entity experiences are examined from perspectives of evolutionary psychology and neurophenomenology. Their similarities with other entity experiences illustrate the need for a general biological explanation of entity experiences. Mechanisms are proposed to involve innate modules, operators, and intelligences that underlie ordinary cognitive inferences and provide the basis for supernatural thought. Methods : Comparisons of ayahuasca and dimethyltryptamine (DMT) entity experiences with other types of entity experiences show their fundamental similarities to conceptions of spirit guides, mythological beings, divinities, [...]

Vollenweider Frontiers in Psychiatry, décembre 2019 doi: 10.3389/fpsyt.2019.00881 Social cognition is a fundamental ability in human everyday lives. Deficits in social functioning also represent a core aspect of many psychiatric disorders. Yet, despite its significance, deficits in social cognition skills are insufficiently targeted by current treatments. Hallucinogens and entactogens have been shown to have the potential to modulate social processing. This article reviews the literature on the influence of hallucinogens and entactogens on social processing in controlled experimental studies in humans and elucidates the underlying neurobiological and neuropharmacological mechanisms. Furthermore, [...]

Lee April 17, 2019 https://www.projectcbd.org/culture/psychedelics-cannabis-therapeutics High doses of THC are hallucinogenic, and microdosing LSD is a lot like CBD. These mighty molecules can relieve human suffering and they act through the endocannabinoid system. Although it may not be obvious during these Trump-rattled times, we’re in the midst of a psychedelic revival. There is more interest than ever before in experimenting with LSD, magic mushrooms, ayahuasca, ketamine, and other psychedelic drugs. This renaissance is happening without all the fanfare of the day-glo Sixties, when lysergic acid diethylamide (LSD) escaped from the laboratory and assumed the lead role in an improbable [...]

Strassman’s top selling book documented groundbreaking clinical trials with the powerful mind altering compound DMT (N,N-dimethyltryptamine) conducted at the University of New Mexico in the early 1990s. Inflected with Buddhist metaphysics, the book proposed that DMT secreted from the pineal gland enables transit of the [...]

Société Psychédélique Française, novembre 2019 D’après l’Organisation mondiale de la santé, une personne sur quatre dans le monde sera affectée à un moment donné de sa vie par des troubles mentaux ou neurologiques. Or, après des décennies d’oubli, nous assistons en dehors de nos frontières à un regain de la recherche clinique psychothérapeutique sur les psychédéliques et au développement de thérapies novatrices impliquant ces substances. Les psychédéliques sont des composés, issus du monde vivant ou de la chimie, provoquant des effets analogues sur le psychisme [...]
