Cannabidiol regulates behavioural alterations and gene expression changes induced by spontaneous cannabinoid withdrawal Francisco Navarrete, Auxiliadora Aracil-Fernández and Jorge Manzanares British Journal of Pharmacology, 2018. Doi : 10.1111/bph.14226 BACKGROUND AND PURPOSE Cannabidiol (CBD) represents a promising therapeutic tool for treating cannabis use disorder (CUD). This study aimed to evaluate the effects of CBD on the behavioural and gene expression alterations induced by spontaneous cannabinoid withdrawal. EXPERIMENTAL APPROACH Spontaneous cannabinoid withdrawal was evaluated 12 h after cessation of CP-55,940 treatment (0.5 mg·kg1 every 12 h, i.p.; 7 days) in C57BL/6J mice. The effects of CBD (5, 10 and 20 mg·kg1, i.p.) on withdrawal-related behavioural signs were evaluated by [...]

Cannabis use is one of the environmental fac- tors more repeatedly related to an increase the risk of developing a psychotic episode, while its [...]

Nomikos & George Panagis Psychopharmacology, 2006, 188, 293–305 Doi : 10.1007/s00213-006-0506-0 Abstract Rationale : The endogenous cannabinoid system is responsive to the neurobiological actions of Δ9-tetrahydrocannabinol (THC) and other cannabinoid ligands. While numerous studies have focused on the behavioral and pharmacological effects of THC and cannabinoid agonists in experimental animals, most recent work focuses on compounds that modulate endocannabinoid neurotransmission. However, the relevant studies concerning the ability of endocannabinoid modulators to modify reward processes in experimental animals remain rather scarce. Objectives : The present study examined the effects of drugs modulating endocannabinoid neurotransmission on [...]
