Psilocybin, in 10 mg or 25 mg doses, has no short- or long-term detrimental effects in healthy people

Psilocybin, in 10 mg or 25 mg doses, has no short- or long-term detrimental effects in healthy people Patrick O'Brien King’s College London News Center, 2022 https://www.kcl.ac.uk/news/psilocybin-in-10mg-or-25mg-doses-has-no-short-or-long-term-detrimental-effects-in-healthy-people   Psilocybin can be safely administered at doses of either 10mg or 25mg to up to six participants simultaneously. New research from the Institute of Psychiatry, Psychology, & Neuroscience (IoPPN) at King’s College London, in partnership with COMPASS Pathways, has established that psilocybin can be safely administered at doses of either 10mg or 25mg to up to six participants simultaneously. The research, published in The Journal of Psychopharmacology, is an essential first step in demonstrating the safety and feasibility of [...]

Assessing the risk-benefit profile of classical psychedelics : a clinical review of second-wave psychedelic research, David Bender & David J. Hellerstein, 2022.

Assessing the risk-benefit profile of classical psychedelics : a clinical review of second-wave psychedelic research David Bender & David J. Hellerstein Psychopharmacology (Berl), 2022. Doi : 10.1007/s00213-021-06049-6 Abstract Rationale : A broad reassessment of the potential benefits of psychedelic drugs has led to the initiation of multiple major clinical trials in an effort to advance their status to become FDA-approved medications, as well as local legislative efforts to legalize or decriminalize their use. Objectives : To use recently published data to assess potential risks and benefits of psychedelic drugs as therapeutics, as well as to synthesize what is currently known in order [...]

Assessing the treatment of cannabidiolic acid methyl ester: a stable synthetic analogue of cannabidiolic acid on c‑Fos and NeuN expression in the hypothalamus of rats Eric Murillo‑Rodríguez, Roger G. Pertwee, Raphael Mechoulam et al., 2021

Assessing the treatment of cannabidiolic acid methyl ester: a stable synthetic analogue of cannabidiolic acid on c‑Fos and NeuN expression in the hypothalamus of rats Eric Murillo‑Rodríguez, Diana Millán‑Aldaco, Gloria Arankowsky‑Sandoval, Tetsuya Yamamoto, Roger G. Pertwee, Linda Parker and Raphael Mechoulam     Abstract Background : Cannabidiol (CBD), the non-psychotropic compound from Cannabis sativa, shows positive results on controlling several health disturbances; however, comparable data regarding additional chemical from C. sativa, such as cannabidiolic acid (CBDA), is scarce due to its instability. To address this limitation, a stable CBDA analogue, CBDA methyl ester (HU-580), was synthetized and showed CBDA-like effects. Recently, we described that HU-580 increased [...]

Flashback phenomena after administration of LSD and psilocybin in controlled studies with healthy participants, Felix Müller et al., 2022

Flashback phenomena after administration of LSD and psilocybin in controlled studies with healthy participants Felix Müller, Elias Kraus, Friederike Holze, Anna Becker, Laura Ley, Yasmin Schmid, Patrick Vizeli, Matthias E. Liechti, Stefan Borgwardt Psychopharmacology, 2022, 1-11. doi : 10.1007/s00213-022-06066-z   Abstract Background : LSD and psilocybin are increasingly used in phase I trials and evaluated as therapeutic agents for mental disorders. The phenomenon of reoccurring drug-like experiences after the acute substance effects have worn off was described for both substances and especially attributed to LSD. According to the DSM-V, the persisting and distressing manifestation of these experiences is called hallucinogen-persisting perception disorder (HPPD). Data on both conditions [...]

Medical cannabis for severe treatment resistant epilepsy in children : a case-series of 10 patients, Rayyan Zafar, David Nutt et al., 2021

Medical cannabis for severe treatment resistant epilepsy in children : a case-series of 10 patients Rayyan Zafar, Anne Schlag, Lawrence Phillips, David J Nutt BMJ Paediatrics Open, 2021, 5, e001234. doi : 10.1136/bmjpo-2021-001234 ABSTRACT Objectives : To report the findings of a case-series of 10 children suffering with intractable epilepsies in the UK to determine the feasibility for using whole-plant cannabis medicines to treat seizures in children. Setting : This study was conducted retrospectively through collecting clinical data from caretakers and clinicians on study outcome variables. Participants were recruited through the MedCann Support and End our Pain charity groups which are patient representative groups that support children [...]

Whole-plant Cannabis Linked to Large Reduction in Seizures Kelli Whitlock Burton, Medscape, 2021.

Whole-plant Cannabis Linked to Large Reduction in Seizures Kelli Whitlock Burton Medscape - Dec 29, 2021. https://www.medscape.com/viewarticle/965756   Whole-plant cannabis is linked to a significant reduction in seizures in children with severe treatment-resistant epilepsy, early research suggests. In a small case series, children with severe treatment-resistant epilepsy treated with a range of whole-plant extract cannabis-based medical products (CBMPs) reported an 86% reduction in monthly seizures. All participants had no improvement with traditional antiepileptic drugs (AEDs). The study adds to a small but growing body of research investigating whole-plant cannabis medicines containing tetrahydrocannabinol (THC) in pediatric epilepsies. Rayyan Raja Zafar "Although we have previously noted the superior efficacy of whole-plant medical cannabis is a previous [...]

Epidiolex Plus THC May Lower Seizures in Pediatric Epilepsy Randy Dotinga, Medscape.com, 2021.

Epidiolex Plus THC May Lower Seizures in Pediatric Epilepsy Randy Dotinga  Medscape.com - Oct 14, 2021. https://www.medscape.com/viewarticle/960842   Children and young adults with epilepsy had fewer seizures after combination treatment with the drug Epidiolex, which contains the cannabidiol (CBD), and various doses of tetrahydrocannabinol (THC), the component of cannabis that makes people high in larger quantities, researchers reported. "THC can contribute to seizure control and mitigation some of the side effects of CBD," said study coauthor and Austin, Tex., child neurologist Karen Keough, MD, in an interview. Keough and colleagues presented their findings at the 50th annual meeting of the Child Neurology Society. In a landmark move, the Food and [...]

Long-Term Efficacy for Epidiolex in Resistant Epilepsy, Pauline Anderson, Medscape.com, 2018.

Long-Term Efficacy for Epidiolex in Resistant Epilepsy Pauline Anderson  Medscape - Dec 17, 2018. https://www.medscape.com/viewarticle/906653   NEW ORLEANS — Results of open-label extension trials show the recently approved drug Epidiolex (GW Pharmaceuticals), a purified formulation of cannabidiol (CBD), is safe and effective beyond a year in patients with Lennox-Gastaut Syndrome (LGS) and Dravet Syndrome, two rare and resistant epilepsy types. "We now have long-term data to say that it still works; the efficacy is not going to drop off, and more importantly, it's still going to be safe and you're not going to learn anything new down the road," study author Anup D. Patel, MD, Section Chief of Pediatric Neurology, [...]

Data Supporting Cannabis for Childhood Epilepsy Remain Scarce, Will Pass, Medscape.com,  2021

Data Supporting Cannabis for Childhood Epilepsy Remain Scarce Will Pass Medscape.com, September 13, 2021 https://www.medscape.com/viewarticle/958616   Cannabis-based medicinal products (CBMPs) have shown early promise for refractory childhood epilepsy, but positive media attention, as well as pressure from politicians and marijuana advocacy groups, should not supplant clinical trials and acceptable standards of evidence, according to two leading experts. In a recent invited review article, Martin Kirkpatrick, MD, of the University of Dundee (Scotland), and Finbar O'Callaghan, MD, PhD, of University College London suggested that childhood epilepsy may be easy terrain for commercial interests to break ground, and from there, build their presence. "Children with epilepsy are at risk of being [...]
