Using Cannabis To Help You Sleep: Heightened Frequency of Medical Cannabis Use among Those with PTSD Marcel O. Bonn-Miller, Kimberly A. Babson, and Ryan Vandrey Drug and Alcohol Dependence, 2014, 136, 162–165. doi:10.1016/j.drugalcdep.2013.12.008 Abstract Background : The use of cannabis for medical purposes is proliferating in the U.S., and PTSD is an explicitly approved condition for accessing medical cannabis in 5 states. Prior research suggests that people with PTSD often use cannabis to help cope with their condition, and that doing so results in more frequent and problematic cannabis use patterns. Specific coping motivations, such as sleep improvement, among medical cannabis users, have not been [...]

Babson The American Journal of Drug and Alcohol Abuse, 2014, 40, (1), 23-30. doi : 10.3109/00952990.2013.821477. OBJECTIVES Little research has investigated the demographic and symptom profile of medical cannabis users in states in the USA that have legalized cannabis use. METHODS In the present cross-sectional study, we investigated the demographic profile of 217 adults currently receiving medical cannabis, as well as differences in problematic use and perceived helpfulness in terms of (i) symptoms of psychological disorders and pain, and (ii) motives for use. RESULTS Findings indicated that medical cannabis users (i) [...]
Lire la suite2-Linoleoylglycerol Is a Partial Agonist of the Human Cannabinoid Type 1 Receptor that Can Suppress 2-Arachidonolyglycerol and Anandamide Activity Leanne Lu, Gareth Williams, and Patrick Doherty* Cannabis and Cannabinoid Research, 2019 Doi : 10.1089/can.2019.0030 Abstract Introduction : The cannabinoid type 1 (CB1) receptor and cannabinoid type 2 (CB2) receptor are widely expressed in the body and anandamide (AEA) and 2-arachidonoylglycerol (2-AG) are their best characterized endogenous ligands. The diacylglycerol lipases (diacylglycerol lipase alpha and diacylglycerol lipase beta) not only synthesize essentially all the 2-AG in the body but also generate other monoacylglycerols, including 2- linoleoylglycerol (2-LG). This lipid has been proposed to modulate endocannabinoid (eCB) [...]

Milosev, Nikolas Psathakis, Natalia Szejko, Ewgeni Jakubovski, and Kirsten R. Müller-Vahl Cannabis and Cannabinoid Research, 2019, https://doi.org/10.1089/can.2018.0050 Abstract Introduction : Gilles de la Tourette syndrome (GTS) is a neuropsychiatric disorder that is characterized by motor and vocal tics and psychiatric comorbidities, including attention deficit/hyperactivity disorder (ADHD) and obsessive-compulsive behavior/disorder (OCB/OCD). From anecdotal reports and preliminary controlled studies, it is suggested that cannabis-based medicine (CBM) may improve tics and comorbidities in adults with GTS. This study was designed to further investigate efficacy and safety of [...]

The introduction of dopamine D2 receptor antagonists in the 1950s revolutionised the treatment of psychotic disorders and they remain the mainstay of our treatment arsenal for psychosis. However, traditional antipsychotics are associated with a number of side effects and a significant proportion of patients do not achieve an adequate remission of symptoms. There is therefore a need for novel interventions, particularly those with a non-D2 antagonist mechanism of [...]

Renata Androvicova, Jiri Horacek, Tibor Stark, Filippo Drago, Vincenzo Micale Pharmacological Research, 2017, 115, 200–208 http://dx.doi.org/10.1016/j.phrs.2016.11.021 a b s t r a c t The endocannabinoid system (ECS), which is composed of the cannabinoid receptors types 1 and 2 (CB1 and CB2) for marijuana’s psychoactive ingredient 9-tetrahydrocannabinol (9-THC), the endogenous ligands (AEA and 2-AG) and the enzymatic systems involved in their biosynthesis and degradation, recently emerged as important modulator of emotional and non-emotional behaviors. For centuries, in addition to its recreational actions, several contradictory claims regarding the effects of Cannabis use in sexual functioning and behavior [...]

Boks European Neuropsychopharmacology, 2014, 24 ,(1), 51–64. http://dx.doi.org/10.1016/j.euroneuro.2013.11.002 Abstract Although cannabis use is associated with an increased risk of developing psychosis, the cannabis constituent cannabidiol (CBD) may have antipsychotic properties. This review concisely describes the role of the endocannabinoid system in the development of psychosis and provides an overview of currently available animal, human experimental, imaging, epidemiological and clinical studies that investigated the antipsychotic properties of CBD. In this targeted literature review we performed a search for English articles using Medline and EMBASE. Studies were selected if [...]

Doi : 10.3928/02793695-20190813-01 ABSTRACT The increasing public acceptance of cannabis and the proliferation of cannabis products in the market-place has coincided with more patients using the drug as a substitute for psychiatric medications or as an adjunctive treatment modality for psychiatric conditions, despite limited evidence of efficacy. With a goal of furthering harm-reduction eff orts in psychiatric nursing, the current article reviews the fundamentals of the endocannabinoid system in humans and the exogenous phytocannabinoids that act on this regulatory [...]

It has been proposed to have a therapeutic potential over a wide range of neuropsychiatric disorders. In this narrative review, we have summarized a selected number of pre-clinical and clinical studies, examining the effects of CBD in neuropsychiatric [...]
Lire la suiteRole of the Endocannabinoid System in the Pathophysiology of Schizophrenia M. Fakhoury Molecular Neurobiology, 2017, 54, (1), 768-778. doi: 10.1007/s12035-016-9697-5 ABSTRACT : The endocannabinoid system (ECS) is a group of neuromodulatory lipids, enzymes, and receptors involved in numerous behavioral and physiological processes such as mood, memory, and appetite. Recently, longitudinal and postmortem studies have shown that the ECS might be involved in neuropsychiatric disorders like schizophrenia. However, despite the large amount of research, our knowledge of the ECS and its implication in this debilitating disorder is still largely limited. This review aims at providing a comprehensive overview of the current state of knowledge of the [...]
