Flash info 19/11/2020 MILDECA Covid-19 : isolement et conditions de travail favorisent les conduites addictives Depuis le premier confinement instauré en mars dernier, l’isolement au travail, l’augmentation des objectifs en matière de performance ainsi que la charge de travail ont joué un rôle dans l’augmentation des consommations de substances psychoactives. C’est ce que montre l’enquête publiée ce jour par la MILDECA et ses partenaires. Pour documenter l’évolution des consommations de substances psychoactives et les conditions de travail en période d’épidémie de Covid-19, la MILDECA et ses partenaires - ANSES, Anact, INRS, OFDT, Santé Publique France et le COCT * - ont commandité une enquête [...]

Les effets antidépresseurs de la kétamine élucidés, Florence Rosier, Le Monde, 16 avril 2019

Les effets antidépresseurs de la kétamine élucidés Utilisée de longue date comme anesthésique, cette molécule vient d’être autorisée comme antidépresseur aux Etats-Unis. Par Florence Rosier Publié le 16 avril 2019 à 06h00 - https://www.lemonde.fr/sciences/article/2019/04/16/les-effets-antidepresseurs-de-la-ketamine-elucides_5450737_1650684.html   La kétamine est une molécule à surprises. Et pas seulement pour ceux qui recherchent ses effets hallucinogènes en la détournant de ses applications médicales. Depuis les années 1970, elle est largement utilisée comme anesthésique à usage humain ou vétérinaire. Mais elle est aussi dotée de puissants effets antidépresseurs, découverts voici plus de vingt ans. Or, ceux-ci viennent d’être doublement reconnus : au plan réglementaire, par la toute-puissante agence américaine du médicament (FDA) ; [...]

High Times for Painful Blues : The Endocannabinoid System in Pain-Depression Comorbidity, Marie Fitzgibbon et al., 2016

High Times for Painful Blues : The Endocannabinoid System in Pain-Depression Comorbidity Marie Fitzgibbon, David P. Finn,  Michelle Roche International Journal of Neuropsychopharmacology, 2016, 19, (3), 1–20 doi : 10.1093/ijnp/pyv095   Abstract Depression and pain are two of the most debilitating disorders worldwide and have an estimate co-occurrence of up to 80%. Comorbidity of these disorders is more difficult to treat, associated with significant disability and impaired healthrelated quality of life than either condition alone, resulting in enormous social and economic cost. Several neural substrates have been identified as potential mediators in the association between depression and pain, including neuroanatomical reorganization, monoamine and neurotrophin depletion, dysregulation [...]

Unique treatment potential of cannabidiol for the prevention of relapse to drug use: preclinical proof of principle, Gustavo Gonzalez-Cuevas et al., 2018

Unique treatment potential of cannabidiol for the prevention of relapse to drug use: preclinical proof of principle Gustavo Gonzalez-Cuevas, Remi Martin-Fardon, Tony M. Kerr, David G. Stouffer, Loren H. Parsons, Dana C. Hammell, Stan L. Banks, Audra L. Stinchcomb and Friedbert Weiss Neuropsychopharmacology, 2018, 43, 2036–2045. Doi : 10.1038/s41386-018-0050-8   Cannabidiol (CBD), the major non-psychoactive constituent of Cannabis sativa, has received attention for therapeutic potential in treating neurologic and psychiatric disorders. Recently, CBD has also been explored for potential in treating drug addiction. Substance use disorders are chronically relapsing conditions and relapse risk persists for multiple reasons including craving induced by drug contexts, susceptibility to [...]

Developmental consequences of perinatal cannabis exposure : behavioral and neuroendocrine effects in adult rodents, Patrizia Campolongo et al., 2011

Developmental consequences of perinatal cannabis exposure : behavioral and neuroendocrine effects in adult rodents Patrizia Campolongo, Viviana Trezza, Patrizia Ratano, Maura Palmery & Vincenzo Cuomo Psychopharmacology, 2011, 214, 5–15 Doi : 10.1007/s00213-010-1892-x   Abstract Rationale : Cannabis is the most commonly used illicit drug among pregnant women. Since the endocannabinoid system plays a crucial role in brain development, maternal exposure to cannabis derivatives might result in longlasting neurobehavioral abnormalities in the exposed offspring. It is difficult to detect these effects, and their underlying neurobiological mechanisms, in clinical cohorts, because of their intrinsic methodological and interpretative issues. Objectives : The present paper reviews relevant rodent studies examining the [...]

Antidepressant-like effects of β-caryophyllene on restraint plus stress-induced depression, Eun-Sang Hwang et al., 2020

Antidepressant-like effects of β-caryophyllene on restraint plus stress-induced depression Eun-Sang Hwang, Hyun-Bum Kim, Seok Lee, Min-Jeong Kim, Kwan-Joong Kim, Gaeul Han, Se-Young Han, Eun-A Lee, Jeong-Hee Yoon, Dae-Ok Kim, Sungho Maeng, Ji-Ho Park Behavioural Brain Research, 2020, 380, 112439 doi : 10.1016/j.bbr.2019.112439   A B S T R A C T Chronic stress is depressogenic by altering neurotrophic and neuroinflammatory environments of the organism. The endocannabinoid system controls cognitive and emotional responses related with stress through the interaction with endocannabinoid receptors. β-Caryophyllene (BCP) is a CB2 agonist that exhibited anti-inflammatory, analgesic effects but minimal psychoactive effects. To test if BCP exhibits antidepressant-like action, animals were chronically restrained with additional [...]
