Early Consumption of Cannabinoids : From Adult Neurogenesis to Behavior, Citlalli Netzahualcoyotzi et al., 2021

Early Consumption of Cannabinoids : From Adult Neurogenesis to Behavior Citlalli Netzahualcoyotzi, Luis Miguel Rodríguez-Serrano, María Elena Chávez-Hernández and Mario Humberto Buenrostro-Jáuregui International Journal of Molecular Sciences, 2021, 22, 7450. doi : 10.3390/ijms22147450   Abstract The endocannabinoid system (ECS) is a crucial modulatory system in which interest has been increasing, particularly regarding the regulation of behavior and neuroplasticity. The adolescent–young adulthood phase of development comprises a critical period in the maturation of the nervous system and the ECS. Neurogenesis occurs in discrete regions of the adult brain, and this process is linked to the modulation of some behaviors. Since marijuana (cannabis) is the most consumed illegal [...]

Cannabinoids and the endocannabinoid system in reward processing and addiction: from mechanisms to interventions, Rainer Spanagel, 2020

Cannabinoids and the endocannabinoid system in reward processing and addiction: from mechanisms to interventions Rainer Spanagel, PhD Dialogues in Clinical Neuroscience, 2020, 22, (3), 241-250. doi : 10.31887/DCNS.2020.22.3/rspanagel   The last decades have seen a major gain in understanding the action of cannabinoids and the endocannabinoid system in reward processing and the development of addictive behavior. Cannabis-derived psychoactive compounds such as Δ9-tetrahydrocannabinol and synthetic cannabinoids directly interact with the reward system and thereby have addictive properties. Cannabinoids induce their reinforcing properties by an increase in tonic dopamine levels through a cannabinoid type 1 (CB1) receptor–dependent mechanism within the ventral tegmental area. Cues that are conditioned [...]

The (Poly)Pharmacology of Cannabidiol in Neurological and Neuropsychiatric Disorders : Molecular Mechanisms and Targets, Rosa Maria Vitale et al., 2021

The (Poly)Pharmacology of Cannabidiol in Neurological and Neuropsychiatric Disorders: Molecular Mechanisms and Targets Rosa Maria Vitale, Fabio Arturo Iannotti and Pietro Amodeo International journal of Molecular Sciences, 2021, 22, 4876, 1-20. Doi : 10.3390/ijms22094876   Abstract : Cannabidiol (CBD), the major nonpsychoactive Cannabis constituent, has been proposed for the treatment of a wide panel of neurological and neuropsychiatric disorders, including anxiety, schizophrenia, epilepsy and drug addiction due to the ability of its versatile scaffold to interact with diverse molecular targets that are not restricted to the endocannabinoid system. Albeit the molecular mechanisms responsible for the therapeutic effects of CBD have yet to be fully elucidated, many [...]

Role of Cannabidiol in the Therapeutic Intervention for Substance Use Disorders, Francisco Navarrete et al., 2021

Role of Cannabidiol in the Therapeutic Intervention for Substance Use Disorders Francisco Navarrete, María Salud García-Gutiérrez, Ani Gasparyan, Amaya Austrich-Olivares and Jorge Manzanares Frontiers in Pharmacology, 2021, 12, Article 696010, 1-24. Doi : 10.3389/fphar.2021.626010   Drug treatments available for the management of substance use disorders (SUD) present multiple limitations in efficacy, lack of approved treatments or alarming relapse rates. These facts hamper the clinical outcome and the quality of life of the patients supporting the importance to develop new pharmacological agents. Lately, several reports suggest that cannabidiol (CBD) presents beneficial effects relevant for the management of neurological disorders such as epilepsy, multiple sclerosis, Parkinson’s, or [...]

CB2 Receptor Involvement in the Treatment of Substance Use Disorders, Francisco Navarrete et al., 2021

CB2 Receptor Involvement in the Treatment of Substance Use Disorders Francisco Navarrete, María S. García-Gutiérrez, Ani Gasparyan, Daniela Navarro and Jorge Manzanares Biomolecules, 2021, 11, 1556, 1-18. Doi : 10.3390/biom11111556   Abstract The pharmacological modulation of the cannabinoid receptor 2 (CB2r) has emerged as a promising potential therapeutic option in addiction. The purpose of this review was to determine the functional involvement of CB2r in the effects produced by drugs of abuse at the central nervous system (CNS) level by assessing evidence from preclinical and clinical studies. In rodents, several reports suggest the functional involvement of CB2r in the effects produced by drugs of abuse such [...]

Learning to Let Go : A Cognitive-Behavioral Model of How Psychedelic Therapy Promotes Acceptance, Max Wolf et al., 2020

Learning to Let Go : A Cognitive-Behavioral Model of How Psychedelic Therapy Promotes Acceptance Max Wolff, Ricarda Evens, Lea J. Mertens, Michael Koslowski, Felix Betzler, Gerhard Gründer and Henrik Jungaberle Frontiers in Psychiatry, February 2020 | Volume 11 | Article 5, 1-13. doi : 10.3389/fpsyt.2020.00005   The efficacy of psychedelic-assisted therapies for mental disorders has been attributed to the lasting change from experiential avoidance to acceptance that these treatments appear to facilitate. This article presents a conceptual model that specifies potential psychological mechanisms underlying such change, and that shows substantial parallels between psychedelic therapy and cognitive behavioral therapy: We propose that in the carefully controlled [...]
