The 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, [...]
Lire la suiteA 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 [...]

Cannabinoids exhibit their action by a modulation of the signaling pathways crucial in the control of cell proliferation and survival. Many in vitro and in vivo experiments have shown that cannabinoids inhibit proliferation of cancer cells, stimulate autophagy and apoptosis, and have also a potential to inhibit angiogenesis [...]

Doi : 10.1186/s12888-019-2409-8 Abstract Background : Medicinal cannabis has received increased research attention over recent years due to loosening global regulatory changes. Medicinal cannabis has been reported to have potential efficacy in reducing pain, muscle spasticity, chemotherapy-induced nausea and vomiting, and intractable childhood epilepsy. Yet its potential application in the field of psychiatry is lesser known. Methods : The first clinically-focused systematic review on the emerging medical application of cannabis across all major psychiatric disorders was conducted. Current evidence regarding [...]

Melville Medscape, January 28, 2020 Medscape Medical News © 2020 Cancer patients who were treated with a one-time, single dose of the psychedelic drug psilocybin, combined with psychotherapy, showed significant benefits on measures of emotional and existential distress nearly 5 years after receiving the therapy, new research indicates. In addition to reporting improved well-being or life satisfaction, some patients rated the treatment as being "among the most personally meaningful and spiritually significant experiences of their lives," the authors note. The study, the longest-spanning evaluation to date of the effects of psilocybin in the treatment of cancer-related psychiatric distress, was [...]
Lire la suitePsilocybin-Assisted Therapy : A Review of a Novel Treatment for Psychiatric Disorders Kelan Thomas, Pharm.D., M.S., Benjamin Malcolm, Pharm.D., M.P.H., and Dan Lastra, B.S. Journal of Psychoactive Drugs, 2017 Doi : 10.1080/02791072.2017.1320734 Abstract Recent research suggests that functional connectivity changes may be involved in the pathophysiology of psychiatric disorders. Hyperconnectivity in the default mode network has been associated with psycho-pathology, but psychedelic serotonin agonists like psilocybin may profoundly disrupt these dysfunctional neural network circuits and provide a novel treatment for psychiatric disorders. We have reviewed the current literature to investigate the efficacy and safety of psilocybin-assisted therapy for the treatment of psychiatric disorders. There were [...]

Presently, the field encourages the use of anti-depressants, anti-anxiety agents, and antipsychotics to relieve symptoms from which patients suffer. Despite continuous breakthroughs in psychiatric medicine, many writers feel that this approach is questionable. For [...]
Lire la suiteCannabis for Sleep: Short-Term Benefit, Long-Term Disruption ? Michael Vlessides Medscape, January 24, 2020 https://www.medscape.com/viewarticle/924202_print Patients suffering from chronic pain who take medicinal cannabis to initiate and maintain sleep appear to experience short-term benefit, but long-term use may ultimately disrupt slumber, new research shows. Investigators found whole-plant medical cannabis use was associated with fewer problems with respect to waking up at night, but they also found that frequent medical cannabis use was associated with more problems initiating and maintaining sleep. "Cannabis may improve overall sleep in the short term," study investigator Sharon Sznitman, PhD, University of Haifa Faculty of Social Welfare and Health Sciences in Israel, [...]

Cavnar (eds.), "Plant Medicines, Healing and Psychedelic Science", Springer International Publishing AG, part of Springer Nature 2018 doi : 10.1007/978-3-319-76720-8_12 Abstract DMT (N,N-dimethyltryptamine) is a powerful tryptamine that has experienced growing appeal in the last decade, independent from ayahuasca, the Amazonian visionary brew in which it is an integral ingredient. Investigating user reports available from literary and online sources, this chapter focuses on the gnosis potency associated with the DMT “breakthrough” experience. I explore the parameters of the tryptaminal state and, in particular, the extraordinary paragnosis associated with [...]
