Cannabis is the most-used recreational drug worldwide, with a high prevalence of use among adolescents. In animal models, long-term adverse effects were reported following chronic adolescent exposure to the main psychotomimetic component of the plant, delta-9-tetrahydrocannabinol (THC). However, these studies investigated the effects of pure THC, without taking into account other cannabinoids...

Although several findings indicate an association between adolescent cannabis abuse and the risk to develop schizophrenia later in life, the evidence for a causal relationship is still inconclusive. In the present study, we investigated the emergence of psychotic-like behavior in adult female rats chronically exposed to delta-9-tetrahydrocannabinol (THC) during adolescence. To this aim, female...

Marijuana and hashish are the illicit drugs most frequently used by human adolescents. Given the continued neurodevelopment throughout adolescence, adolescents may be more vulnerable than adults to certain neural consequences of heavy marijuana use. This study aimed to assess whether an experimental model of adolescent chronic exposure to Delta9-tetrahydrocannabinol (THC), may induce lasting...

BACKGROUND AND PURPOSE: Drugs targeting brain kappa-opioid receptors produce profound alterations in mood. In the present study we investigated the possible anxiolytic- and antidepressant-like effects of the kappa-opioid receptor agonist salvinorin A, the main active ingredient of Salvia divinorum, in rats and mice. EXPERIMENTAL APPROACH: Experiments were performed on male Sprague-Dawley rats...

Few and often contradictory reports exist on the long-term neurobiological consequences of cannabinoid consumption in adolescents. The endocannabinoid system plays an important role during the different stages of brain development as cannabinoids influence the release and action of different neurotransmitters and promote neurogenesis. This study tested whether long-lasting interference by...

The recreational drug, Salvinorin A, derived from the plant of Salvia divinorum, is a potent and selective kappa-opioid receptor agonist. The abuse of selective k-agonists is a novel phenomenon, the mechanism of which is not fully understood. We investigated salvinorin A given SC on the conditioned place preference (.05-160 microg/kg) and intracerebroventricular (ICV) self-administration (.01-1...
