Cannabinoids and Endocannabinoids, and Prospective Modulation of EC Signaling in Neurodegenerative, Cardiovascular and Allied Disorders Dr Vinod Nikhra Preprint, May 2019 Doi : 10.13140/RG.2.2.36649.24165 ABSTRACT CANNABIS USE AND AVAILABILITY: The Cannabis derivatives have been used for recreational and medicinal purposes since ancient times. Because of the additive potential of cannabis products, their sale, possession and use are variously regulated in different countries throughout the world. Still as a psychoactive drug, cannabis continues to find extensive favour among recreational and medical users in the USA and other countries having led to decriminalise cannabis use for recreational and medicinal purposes. ECS: RECEPTORS, LIGANDS AND SIGNALING: The endocannabinoid system comprises [...]

Doi : 10.3390/life11030214 Abstract : Post-Traumatic Stress Disorder (PTSD) is a complex disorder involving dysregulation of stress-related hormones and neurotransmitter systems. Research focused on the endocannabinoid system (eCBS) for anxiety and stress regulation, cognitive and emotional responses modulation and aversive memories extinction, leading to the hypothesis that it could represent a possible alternative treatment target for PTSD. In this systematic review, we summarize evidence about the efficacy and safety of medicinal cannabidiol (CBD), D9-tetrahydrocannabinol (D9-THC), and [...]

Bergner, Samantha A. Chesney, Nicholas R. Schumann, Tara Sander Lee, Karen J. Brasel and Cecilia J. Hillard Translational Psychiatry, 2022, 12, 48, 1-12. Doi : 10.1038/s41398-022-01808-1 The endocannabinoid signaling system (ECSS) regulates fear and anxiety. While ECSS hypoactivity can contribute to symptoms of established post-traumatic stress disorder (PTSD), the role of the ECSS in PTSD development following trauma is unknown. A prospective, longitudinal cohort study of 170 individuals (47% non-Hispanic Caucasian and 70% male) treated at a level 1 trauma [...]

Cheer Brain Research, 2015 1628, 233–243. doi : 10.1016/j.brainres.2014.11.034. Abstract Marijuana is the most popular illegal drug worldwide. Recent trends indicate that this may soon change; not due to decreased marijuana use, but to an amendment in marijuana’s illegal status. The cannabinoid type 1 (CB1) receptor mediates marijuana’s psychoactive and reinforcing properties. CB1 receptors are also part of the brain endocannabinoid (eCB) system and support numerous forms of learning and memory, including the conditioned reinforcing properties of cues predicting reward or punishment. This is accomplished [...]

Hohmann Cannabis and Cannabinoid Research, 2021, Volume 6, Number 5, 389-400. DOI: 10.1089/can.2020.0059 Abstract Introduction : Overdose fatalities associated with the opioid epidemic are predictably attributable to druginduced respiratory depression. In terms of illicit opioid abuse, fentanyl is the synthetic opioid responsible for the largest number of overdose deaths. There is, therefore, an urgent need to identify safe and effective therapeutics that can attenuate fentanyl-induced respiratory depression. Identification of effective alternate analgesic strategies that lessen the respiratory depression associated with narcotics would also help [...]
Lire la suiteTroubles anxieux : le CBD peut soulager les symptômes Kalapa Clinic, Barcelone, Espagne By Gesa|30/06/2020 La peur est une réaction naturelle à certaines situations et à certains événements. Elle remplit à la fois une fonction d’avertissement et de protection. Lors d’un trouble anxieux, cependant, elle développe une dynamique propre qui est très stressante pour les personnes concernées. Diverses études et rapports d’expérience indiquent que le cannabinoïde non-psychoactif cannabidiol (CBD) peut soulager leurs symptômes. En Allemagne, le trouble anxieux est la maladie mentale la plus courante, devançant même la dépression. Environ 12 millions de personnes sont touchées, les femmes plus souvent que les hommes (1). Le [...]

Doi : 10.1038/nrm3811 Abstract Isolation and structure elucidation of most of the major cannabinoid constituents — including Δ9-tetrahydrocannabinol (Δ9-THC), which is the principal psychoactive molecule in Cannabis sativa — was achieved in the 1960s and 1970s. It was followed by the identification of two cannabinoid receptors in the 1980s and the early 1990s and by the identification of the endocannabinoids shortly thereafter. There have since been considerable advances in our understanding of the endocannabinoid system and its function in the [...]
Lire la suiteRole of the endogenous cannabinoid system in nicotine addiction : novel insights Islam Hany Gamaleddin, Jose M.Trigo, Aliou B. Gueye, Alexander Zvonok, Alexandros Makriyannis, Steven R. Goldberg and Bernard Le Foll Frontiers in Psychiatry, 2015, Vol 6, Article 41, 1-12. doi : 10.3389/fpsyt.2015.00041 Several lines of evidence have shown that the endogenous cannabinoids are implicated in several neuropsychiatric diseases. Notably, preclinical and human clinical studies have shown a pivotal role of the cannabinoid system in nicotine addiction. The CB1 receptor inverse agonist/antagonist rimonabant (also known as SR141716)was effective to decrease nicotine-taking and nicotine-seeking in rodents, as well as the elevation of dopamine induced by [...]

Kmiec Cannabis and Cannabinoid Research, 2018, Volume 3.1, 259-272 Doi : 10.1089/can.2018.0045 Abstract Introduction : Obesity is treatment-resistant, and is linked with a number of serious, chronic diseases. Adult obesity rates in the United States have tripled since the early 1960s. Recent reviews show that an increased ratio of omega-6 to omega-3 fatty acids contributes to obesity rates by increasing levels of the endocannabinoid signals AEA and 2-AG, overstimulating CB1R and leading to increased caloric intake, reduced [...]

We used the Foramen Rotundum Inflammatory Constriction Trigeminal Infraorbital Nerve injury (FRICT-ION) model to measure the effect of “full-spectrum” whole plant extracted hemp oil on chronic neuropathic pain sensitivity in mice. Methods : Male BALBc mice were [...]
