3,4-methylenedioxymethamphetamine (MDMA, or "Ecstasy") is a popular recreational drug. However, its exposure is often limited to the weekends in a highly stimulating environment. The goal of this study was to investigate the behavioral domains of working and recognition memory within a model of "weekend" Ecstasy use. Rats self-administered MDMA during 2-h sessions on two consecutive days followed by five drug-free days. Coupling this intermittent dosing schedule with a novel object recognition task, we found non-spatial memory impaired after only two "weekends" of self-administered MDMA. Our findings suggest that MDMA at recreational use levels can disrupt memory processes.

Objectives: Students represent a population at risk for substance abuse. That risk may have been exacerbated by the COVID-19 pandemic. We aimed to describe substance abuse among students and to compare consumption according to the university field.

We want to describe the evolution of drug risk perceptions among Spanish adolescents and assessing whether the 2006 peaks in perceived risk of occasional drug use can be explained by question-order changes.
Methods: The subjects were secondary students from a biennial national survey during 2000-2012.

This original study compares the prevalences of drug use for any purpose and for sexualized drug use (SDU) among MSM. It also describes relevant characteristics of first SDU, analyzes to what extent SDU has been the first experience (the gateway) with different drugs by age and explores the correlates of SDU. Study participants included 2,919 HIV-negative MSM attending four HIV/STI diagnosis services in Madrid and Barcelona.

MDMA is a non-selective monoamine releasing stimulant with potent serotonergic effects - a pharmacological effect not typically associated with drugs of misuse or efficacious reinforcers. Nonetheless, MDMA is misused by humans and self-administered by laboratory animals. We have previously shown that repeated exposure to MDMA sensitized both the locomotor activating and reinforcing effects of MDMA in rats.

Background: Ulotaront (SEP-363856) is a trace amine-associated receptor 1 (TAAR1) agonist with 5-hydroxytryptamine type 1A (5-HT1A) agonist activity that is currently in Phase 3 clinical development for the treatment of schizophrenia. Unlike available antipsychotics, the efficacy of ulotaront is not mediated by blockade of dopamine D2 or serotonin 5-HT2A receptors. In a short-term randomized clinical trial, ulotaront has demonstrated significant efficacy in the treatment of adults with an acute exacerbation of schizophrenia.
