The drastic increase in hallucinogenic compounds in illicit drug markets of new psychoactive substances (NPS) is a worldwide threat. Among these, 2, 5-dimetoxy-4-bromo-amphetamine (DOB) and paramethoxyamphetamine (PMA; marketed as “ecstasy”) are frequently purchased on the dark web and consumed for recreational purposes during rave/dance parties. In fact, these two substances seem to induce the...

3,4-methylenedioxymethamphetamine (MDMA) and its derivatives, 2,5-dimethoxy-4-bromo-amphetamine hydrobromide (DOB) and para-methoxyamphetamine (PMA) are recreational drugs whose pharmacological effects have recently been attributed to serotonin 5HT2A/C receptors. However, there is growing evidence that the oxytocin/vasopressin system can modulate some the effects of MDMA. In this study, MDMA...

The effects of salvinorin A (Salvia divinorum principal ingredient), a potent κ-opioid natural hallucinogen, on learning and memory were investigated. Wistar rats were tested in the 8-arm radial maze, for object recognition and passive avoidance tasks for spatial, episodic, and aversive memory. Attention was assessed using a latent inhibition task. Salvinorin A (80-640 μg/kg subcutaneous [sc])...

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...

The hallucinatory effect and potential abuse of salvinorin A, the major ingredient of Salvia divinorum, has not been documented in animals. The effects of salvinorin A on the zebrafish (Danio rerio) model, through its swimming behavior and conditioned place preference (CPP) task, was studied. Swimming activity was determined in a squared observational chamber after an i.m. treatment of...

I.c.v. self‐administration of MDMA (0.01–2 μg per infusion), alone and in combination with CP 55,940 (0.4 μg infusion −1 ), was studied on an operant responding procedure. On the basis of individual preference for one of two levers, developed during training, rats were allowed to self‐administer vehicle from the preferred lever and MDMA from the other. Pressings on the MDMA associated‐lever,...
