Acute cannabidiol treatment attenuates ethanol-induced place preference and reduces aggressivity in group-housed male rats.

Alcohol abuse is a widespread cause of aggressive and impulsive behaviors that impact the users as well as their entourage. However, only a few medications are effective. Recently, cannabidiol has been reported to improve mood disorders and recovery from substance abuse, yet the psychopharmacologic effects of cannabidiol in ethanol-induced drug reward and aggressivity remain unexplored.

Weight status, dietary habits, physical activity, screen time and sleep duration among university students.

Background: University life is a crucial period when dietary habits and lifestyle behaviours are formed and may have long-lasting effects on the development of obesity and related chronic diseases.

Aim: To investigate the association of overweight/obesity with dietary habits, physical activity, screen time and sleep duration among university students.

Methods: A total of 438 students aged 18-26 years were recruited from Mohammed V University in Rabat, Morocco.

Chronic Exposure to WIN55,212-2 During Adolescence Alters Prefrontal Dopamine Turnover and Induces Sensorimotor Deficits in Adult Rats.

Several lines of evidence suggest that chronic exposure to cannabinoids during adolescence may increase the risk of schizophrenia. Studies of the disorder have identified altered cortical dopaminergic neurotransmission. In this study, we hypothesised that heightened endocannabinoid system activation via chronic exposure to a highly potent cannabinoid receptors agonist in adolescent rats would cause long-lasting neurobiological changes that may dramatically alter expression and functions of dopamine metabolising enzymes, comethyl-o-transferase (COMT) and monoamine oxidases MAO-A and MAO-B.
