Functional Connectivity Measures After Psilocybin Inform a Novel Hypothesis of Early Psychosis, Robin L. Carhart-Harris et al., 2012

Functional Connectivity Measures After Psilocybin Inform a Novel Hypothesis of Early Psychosis Robin L. Carhart-Harris, Robert Leech, David Erritzoe, Tim M. Williams, James M. Stone, John Evans, David J. Sharp, Amanda Feilding, Richard G. Wise, and David J. Nutt Schizophrenia Bulletin, 2012 doi: 10.1093/schbul/sbs117   model of psychosis. This study measured the effects of psilocybin on resting-state network and thalamo-cortical functional connectivity (FC) using functional magnetic resonance imaging (fMRI). Fifteen healthy volunteers received intravenous infusions of psilocybin and placebo in 2 task-free resting-state scans. Primary analyses focused on changes in FC between the default-mode- (DMN) and task-positive network (TPN). Spontaneous activity in the DMN is orthogonal [...]

Psychedelic microdosing benefits and challenges : an empirical codebook, Thomas Anderson et al., 2019

Psychedelic microdosing benefits and challenges : an empirical codebook Thomas Anderson, Rotem Petranker, Adam Christopher, Daniel Rosenbaum, Cory Weissman, Le-Anh Dinh-Williams, Katrina Hui, Emma Hapke Harm Reduction Journal, 2019. Doi : 10.1186/s12954-019-0308-4   Abstract Background : Microdosing psychedelics is the practice of consuming very low, sub-hallucinogenic doses of a psychedelic substance, such as lysergic acid diethylamide (LSD) or psilocybin-containing mushrooms. According to media reports, microdosing has grown in popularity, yet the scientific literature contains minimal research on this practice. There has been limited reporting on adverse events associated with microdosing, and the experiences of microdosers in community samples have not been categorized. Methods : In the present study, [...]

Pilot Study of Psilocybin Treatment for Anxiety in Patients With Advanced-Stage Cancer, Charles S. Grob et al., 2010

Pilot Study of Psilocybin Treatment for Anxiety in Patients With Advanced-Stage Cancer Charles S. Grob,  Alicia L. Danforth,  Gurpreet S. Chopra,  Marycie Hagerty, Charles R. McKay, Adam L. Halberstadt,  George R. Greer Archive of  General Psychiatry, 2010, 68, (1), 71–78 doi: 10.1001/archgenpsychiatry.2010.116   Context : Researchers conducted extensive investigations of hallucinogens in the 1950s and 1960s. By the early 1970s, however, political and cultural pressures forced the cessation of all projects. This investigation reexamines a potentially promising clinical application of hallucinogens in the treatment of anxiety reactive to advanced-stage cancer. Objective : To explore the safety and efficacy of psilocybin in patients with advanced-stage cancer and [...]

Serotonergic hallucinogens in the treatment of anxiety and depression in patients suffering from a life-threatening disease : A systematic review, Simon Reiche et al.,

Serotonergic hallucinogens in the treatment of anxiety and depression in patients suffering from a life-threatening disease : A systematic review Simon Reiche, Leo Hermle, Stefan Gutwinskic Henrik Jungaberle, Peter Gasser, Tomislav Majić Progress in Neuropsychopharmacology & Biological Psychiatry, 2018, 81, 1–10 http://dx.doi.org/10.1016/j.pnpbp.2017.09.012   A B S T R A C T Anxiety and depression are some of the most common psychiatric symptoms of patients suffering with lifethreatening diseases, often associated with a low quality of life and a poor overall prognosis. 5-HT2A-receptor agonists (serotonergic hallucinogens, ‘psychedelics’) like lysergic acid diethylamide (LSD) and psilocybin were first investigated as therapeutic agents in the 1960s. Recently, after a long [...]

Chronic, Intermittent Microdoses of the Psychedelic N,N‑Dimethyltryptamine (DMT) Produce Positive Effects on Mood and Anxiety in Rodents, Lindsay P. Cameron et al., 2019

Chronic, Intermittent Microdoses of the Psychedelic N,N‑Dimethyltryptamine (DMT) Produce Positive Effects on Mood and Anxiety in Rodents Lindsay P. Cameron, Charlie J. Benson, Brian C. DeFelice, Oliver Fiehn, and David E. Olson ACS Chemical Neurosciences, 2019 DOI: 10.1021/acschemneuro.8b00692   ABSTRACT : Drugs capable of ameliorating symptoms of depression and anxiety while also improving cognitive function and sociability are highly desirable. Anecdotal reports have suggested that serotonergic psychedelics administered in low doses on a chronic, intermittent schedule, so-called “microdosing”, might produce beneficial effects on mood, anxiety, cognition, and social interaction. Here, we test this hypothesis by subjecting male and female Sprague Dawley rats to behavioral testing following the [...]

The abuse potential of medical psilocybin according to the 8 factors of the Controlled Substances Act, Matthew W. Johnson et al., 2018

The abuse potential of medical psilocybin according to the 8 factors of the Controlled Substances Act Matthew W. Johnson, Roland R. Griffiths, Peter S. Hendricks, Jack E. Henningfiel Neuropharmacology, 2018, 142, 143-166. https://doi.org/10.1016/j.neuropharm.2018.05.012 a b s t r a c t This review assesses the abuse potential of medically-administered psilocybin, following the structure of the 8 factors of the US Controlled Substances Act (CSA). Research suggests the potential safety and efficacy of psilocybin in treating cancer-related psychiatric distress and substance use disorders, setting the occasion for this review. A more extensive assessment of abuse potential according to an 8-factor analysis would eventually be required to [...]

Microdosing psychedelics: More questions than answers? An overview and suggestions for future research Kim P.C. Kuypers, Livia Ng, David Erritzoe, Gitte M. Knudsen, Charles D. Nichols, David E. Nichols, Luca Pani, Anaïs Soula and David Nutt Journal of Psychopharmacology, 2019, 1-10. Doi: 10.1177/0269881119857204   Abstract Background : In the past few years, the issue of ‘microdosing’ psychedelics has been openly discussed in the public arena where claims have been made about their positive effect on mood state and cognitive processes such as concentration. However, there are very few scientific studies that have specifically addressed this issue, and there is no agreed scientific consensus on what microdosing [...]

Salvinorin A : Pharmacology, therapeutic potential and structural considerations of a unique non-nitrogenous selective k-opioid receptor agonist, and active component of the sage Salvia divinorum. Adriano Ciaffoni Graduate School of Life Sciences, Utrecht University July 2014, Utrecht, The Netherlands   Summary Salvia divinorum is a plant indigenous of Oaxaca, Mexico. Traditionally, the plant is used for healing and divinatory purposes. At present, S. divinorum is also used recreationally by teenagers and young adults around the world. The main active component is salvinorin A, a unique non-nitrogenous kappa-opioid receptor agonist with hallucinogenic properties. Scientific interest is high, due to two facts: 1) salvinorin A was the first [...]
