LSD : microdoses festives Céline ZÜND Le Temps, mardi 28 janvier 2020 https://www.letemps.ch/societe/lsd-microdoses-festives?utm_campaign=article_traffic&utm_content=1580242382&utm_medium=social&utm_source=facebook&fbclid=IwAR3v1uDm_lCzk_Bb1XMeRzSxcxr-mHObGhhPeJVK-Fa0y6rczvc3DFJ3H78 La prise de LSD en petites quantités fait toujours plus d'adeptes, dans les milieux festifs, au travail ou en automédication. 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 [...]

Leeming (ed.), "Encyclopedia of Psychology and Religion", # Springer-Verlag GmbH Germany, part of Springer Nature 2018 Doi : 10.1007/978-3-642-27771-9_200181-1 Entheogen is a term coined in the late 1970s by a group of botanists and scholars which refers to any psychoactive agent which allows for “generating the divine within” (Ruck et al. 1979). 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 [...]

Lire la suiteModern Clinical Research on LSD Matthias E Liechti Neuropsychopharmacology, 2017, 42, 2114–2127. doi : 10.1038/npp.2017.86 All modern clinical studies using the classic hallucinogen lysergic acid diethylamide (LSD) in healthy subjects or patients in the last 25 years are reviewed herein. There were five recent studies in healthy participants and one in patients. In a controlled setting, LSD acutely induced bliss, audiovisual synesthesia, altered meaning of perceptions, derealization, depersonalization, and mystical experiences. These subjective effects of LSD were mediated by the 5-HT2A receptor. LSD increased feelings of closeness to others, openness, trust, and suggestibility. LSD impaired the recognition of sad and fearful faces, reduced left [...]

Doi : 10.1556/2054.2019.029 We are in the midst of a psychedelic research renaissance. With research examining the efficacy of psychedelics as a treatment for a range of mental health indications still in its early stages, there is an increasing body of research to show that careful use of psychedelics can yield a variety of benefits in “healthy normals” and so lead to “the betterment of well people.” Psychedelics have been found to modulate neuroplasticity, and usage in a supportive setting can result [...]
Lire la suiteThe effects of microdose LSD on time perception: a randomised, double-blind, placebo-controlled trial Steliana Yanakieva, Naya Polychroni, Neiloufar Family, Luke T. J. Williams, David P. Luke, Devin B. Terhune Psychopharmacology, 2018 Doi : 10.1007/s00213-018-5119-x Abstract Rationale : Previous research demonstrating that lysergic acid diethylamide (LSD) produces alterations in time perception has implications for its impact on conscious states and a range of psychological functions that necessitate precise interval timing. However, interpretation of this research is hindered by methodological limitations and an inability to dissociate direct neurochemical effects on interval timing from indirect effects attributable to altered states of consciousness. Methods : We conducted a randomised, double-blind, [...]

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 [...]
Lire la suiteAccounting for Microdosing Classic Psychedelics Blake Beaton, Heith Copes, Megan Webb, Andy Hochstetler, and Peter S. 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, [...]

C’est toujours le même rituel. J’aime les rituels, ils rationalisent l’absurdité de nos existences et me permettent de continuer à vivre. Réveil engourdi, lavage de mains compulsif, 20 grammes de café et 15 microgrammes de LSD sous la langue. Je suis prête à affronter le monde neurotypique – le monde de ceux qui ne sont pas autistes. Je suis autiste. Je pense, ressens et traite les informations de manière complètement différente. J’ai [...]
