Cannabinoids and Schizophrenia : Risks and Therapeutic Potential, Marc W. Manseau & Donald C. Goff, 2015

Cannabinoids and Schizophrenia : Risks and Therapeutic Potential Marc W. Manseau & Donald C. Goff Neurotherapeutics, 2015, 12, 816–824 DOI 10.1007/s13311-015-0382-6 # The American Society for Experimental NeuroTherapeutics, Inc. 2015   Abstract A convergence of evidence shows that use of Cannabis sativa is associated with increased risk of developing psychotic disorders, including schizophrenia, and earlier age at which psychotic symptoms first manifest. Cannabis exposure during adolescence is most strongly associated with the onset of psychosis amongst those who are particularly vulnerable, such as those who have been exposed to child abuse and those with family histories of schizophrenia. Schizophrenia that develops after cannabis use may have a [...]

The endocannabinoid system : an overview, Natalia Battista et al., 2012

The endocannabinoid system : an overview Natalia Battista, Monia Di Tommaso, Monica Bari and Mauro Maccarrone Frontiers in Behavioral Neuroscience, 2012|Volume 6|Article 9 | 1 doi: 10.3389/fnbeh.2012.00009   Upon the identification of anandamide (AEA) in the porcine brain, numerous studies contributed to the current state of knowledge regarding all elements that form the “endocannabinoidsystem (ECS).” How this complex system of receptors, ligands, and enzymes is integrated in helping to regulate fundamental processes at level of central nervous and peripheral systems and how its regulation and dysregulation might counteract disturbances of such functions, is now a days still under investigation. However, the most recent advances on [...]

Cannabinoids, Endocannabinoids and Cancer, Daniel J. Hermanson and Lawrence J. Marnett , 2011

Cannabinoids, Endocannabinoids and Cancer Daniel J. Hermanson and Lawrence J. Marnett Cancer Metastasis Reviews, 2011, 30, (3-4), 599–612. doi:10.1007/s10555-011-9318-8.   1. Introduction 1.1 Cannabinoid Function Endocannabinoids are bioactive lipids that have a range of interesting activities mediated by two G-protein-coupled receptors (CB1 and CB2) and other putative targets [1-3]. The CB1 receptor is present in the central nervous system and mediates the psychotropic effects of exogenous cannabinoids such as Δ9-tetrahydrocannabinol (THC), the active component of marijuana. In the brain, endocannabinoids and cannabinoids combine with CB1 cannabinoid receptors on axon terminals and regulate ion channel activity and neurotransmitter release [4]. Binding to the CB1 receptor is responsible for [...]

Legal highs : staying on top of the flood of novel psychoactive substances, David Baumeister et al., 2015

Legal highs : staying on top of the flood of novel psychoactive substances David Baumeister, Luis M. Tojo and Derek K. Tracy Therapeutic Advances in Psychopharmacology, 2015, Vol. 5, (2), 97–132 DOI: 10.1177/2045125314559539   Abstract : There has been growing clinical, public, and media awareness and concern about the availability and potential harmfulness of so-called ‘legal highs’, which are more appropriately called new or novel psychoactive substances (NPS). A cat-and-mouse process has emerged wherein unknown chemists and laboratories are producing new, and as yet nonproscribed, compounds for human consumption; and as soon as they are banned, which they inevitably are, slightly modified analogues are produced to [...]
