Cannabinoids Rescue Cocaine-Induced Seizures by Restoring Brain Glycine Receptor Dysfunction Guichang Zou, Xin Zuo, Kai Chen, ..., Guangming Huang, Dan Liu, Wei Xiong Cell Reports, 2020, 30, 4209–4219 Doi : 10.1016/j.celrep.2020.02.106 In Brief Zou et al. identify the glycine receptor as a potential therapeutic target for cannabinoids in treating cocaine-induced seizures. The function of extra-synaptic glycine receptors in the prefrontal cortex and hippocampus is impaired by cocaine and rescued by cannabinoids, therefore leading to the therapeutic effects of cannabinoids in treating cocaine-induced seizures. Highlights Cannabinoids alleviate cocaine-induced seizures (CISs) by glycine receptors (GlyRs) Cannabinoid docking reduces hydrogen-bonding interaction between cocaine and GlyRs The prefrontal cortex and hippocampus [...]

A comprehensive review Gabrielle Campbell, Wayne Hall and Suzanne Nielsen International Review of Psychiatry, 2018, 1-16. Doi : 10.1080/09540261.2018.1509842 ABSTRACT Pre-clinical research supports that cannabinoids reduce opioid dose requirements, but few studies have tested this in humans. This review evaluates ecological and epidemiological studies that have been cited as evidence that medical cannabis use may reduce opioid use and opioidrelated harms. Medline and Embase were searched for relevant articles. Data were extracted on study setting, analyses approach, covariates, and outcomes. Eleven ecological and 14 epidemiological [...]
