Cannabis Robert Hämmig, Ulrich W. Preuss und Michael Soyka January 2019 DOI: 10.1016/B978-3-437-23021-9.00009-6 Kernaussagen ● Die Cannabispflanze, welche die Menschheit seit Jahrtausenden begleitet, wird vi elfältig genutzt: ○ als Lieferant für Fasern zur Herstellung von Tüchern, Schnüren, Seilen und Papier, ○ als Nahrungsmittel (Samenkörner und Öl), ○ als Medizin für Mensch und Tier sowie als Genussmittel. ● Im 19. Jh. hielt Cannabis Einzug in die moderne westliche Medizin und wurde auch als „Freizeitdroge“ genutzt. Aus dieser Zeit stammen detaillierte phänomenologische Bes chreibungen der Effekte. Noch blieb aber der Wirkmechanismus völlig unklar. ● Die erste Hälfte des 20. Jh. ist das „dunkle Zeitalter“ des Cannabis, in dem das Fors chungsinteresse erlahmte. [...]

Owens, Anthony P. Bossis, Alexander B. Belser, Gabrielle Agin-Liebes, Michael P. Bogenschutz and Stephen Ross Frontiers in Pharmacology, 2018, 9, 256 doi: 10.3389/fphar.2018.00256 Abstract : A growing body of evidence shows that existential and spiritual well-being in cancer patients is associated with better medical outcomes, improved quality of life, and serves as a buffer against depression, hopelessness, and desire for hastened death. Historical and recent research suggests a role for psilocybin-assisted psychotherapy in treating cancer-related anxiety and depression. A double-blind controlled trial was performed, where 29 [...]
Lire la suiteREVIEW : Cannabidiol – Recent Advances Raphael Mechoulam, Maximilian Petersa, Eric Murillo-Rodriguez and Lumïr O. Hanus Chemistry and Biodiversity, 2007, 4, 1678-1692. The aim of this review is to present some of the recent publications on cannabidiol (CBD; 2), a major non-psychoactive constituent of Cannabis, and to give a general overview. Special emphasis is laid on biochemical and pharmacological advances, and on novel mechanisms recently put forward, to shed light on some of the pharmacological effects that can possibly be rationalized through these mechanisms. The plethora of positive pharmacological effects observed with CBD make this compound a highly attractive therapeutic entity. Contents 1. Introduction 2. Mechanisms of Cannabidiol Action 2.1. Cannabidiol: an [...]

Methods : Patients aged 4–10 years were randomized 4:1 to CBD (5, 10, or 20 mg/kg/d) or placebo taken twice daily. The double-blind trial comprised 4-week baseline, 3-week treatment (including titration), 10-day taper, and 4-week follow-up periods. Completers [...]

Morrison, J. Crockett, G. Blakey, K. Sommerville Clinical Pharmacology in Drug Development, 2019, PMID : 30791225, DOI : 10.1002/cpdd.665 Abstract GW Pharmaceuticals' formulation of highly purified cannabidiol oral solution is approved in the United States for seizures associated with Lennox-Gastaut and Dravet syndromes in patients aged ≥2 years, for which clobazam, stiripentol, and valproate are commonly used antiepileptic drugs. This open-label, fixed-sequence, drug-drug interaction, healthy volunteer trial investigated the impact of cannabidiol on steady-state pharmacokinetics of clobazam (and N-desmethylclobazam), stiripentol, and valproate; [...]

Vollenweider Proceedings of the National Academy of Sciences ,· January 2019 DOI: 10.1073/pnas.1815129116 Abstract : Psychedelics exert unique effects on human consciousness. The thalamic filter model suggests that core effects of psychedelics may result from gating deficits, based on a disintegration of information processing within cortico–striato–thalamo-cortical (CSTC) feedback loops. To test this hypothesis, we characterized changes in directed (effective) connectivity between selected CTSC regions after acute administration of lysergic acid diethylamide (LSD), and after pretreatment with Ketanserin (a selective serotonin [...]

Fischedick Drug Testing and Analysis, 2012, (wileyonlinelibrary.com) DOI 10.1002/dta.407, Copyright © 2012 John Wiley & Sons, Ltd. Abstract : The medicinal use of Cannabis is increasing as countries worldwide are setting up official programs to provide patients with access to safe sources of medicinal-grade Cannabis. An important question that remains to be answered is which of the many varieties of Cannabis should be made available for medicinal use. Drug varieties of Cannabis are commonly distinguished through the use of popular names, with a major distinction being made between Indica and Sativa types. Although more than [...]

One is that cannabis use by young adults and vulnerable individuals across the lifespan can be a contributory cause of : a cannabis dependence syndrome; schizophreniform psychoses; anxiety and depressive disorders; acute and perhaps chronic cognitive impairment, and structural and functional changes in brain pathways implicated in reward, learning and [...]
