Here we tested in rats effects of the procognitive drugs modafinil and methylphenidate on post-acquisition performance in an object-location paired-associates learning (PAL) task. Modafinil (32; 64 mg/kg) was without effect, while higher (9 mg/kg) but not lower (4.5 mg/kg) doses of methylphenidate impaired PAL performance. Likewise, higher but not…

Monitoring the Future (MTF) is a long-term study of substance use and related factors among U.S. adolescents, college students, and adult high school graduates through age 60. It is conducted annually and supported by the National Institute on Drug Abuse. MTF findings identify emerging substance use problems, track substance use trends, publish…

Background: Transgender adolescents face tremendous social stress in families and schools, which often leads to behavioral health disparities. This study assessed whether rates of substance use were higher among transgender adolescents when compared to nontransgender adolescents. Methods: This study is a secondary data analysis of the 2013-2015…

This occasional paper presents national demographic subgroup data for the 1975-2019 Monitoring the Future (MTF) national survey results on 8th, 10th, and 12th graders' use of drugs, alcohol, and tobacco. The 2018 subgroup data presented in this report accompany the "Monitoring the Future National Survey Results on Drug Use: 1975-2019:…

This study was an investigation into drug use and sources of drug information among secondary school students in Imo State, Nigeria. A sample of 1400 students, aged 16-17 years was studied. Percentages were used to describe the students' drug use and sources of drug information. Chi square was used to verify the four hypotheses postulated for the…

Aims: The non-medical use of prescription stimulants (NMUPS) is an emergent health behaviour among undergraduate college students. This study examined the prevalence, primary motivations and risk factors associated with lifetime and current NMUPS among undergraduates.

A large number of youngsters with autism spectrum disorders (ASD) display comorbid attention deficit/hyperactivity disorder (ADHD) symptoms. However, previous studies are not conclusive whether psychophysiological correlates, like cardiac reactivity, are different for ASD with comorbid ADHD (ASD+) compared to ADHD. Therefore, the current study…

The experiment reported here uses a conditional self-discrimination task to examine the influence of social interaction on the facilitation of self-discrimination in rats. The study is based on a previous report (Penagos- Corzo et al., 2011) showing positive evidence of such facilitation, but extending the exposition to social interaction…

The illicit use of prescription stimulants (IUPS) is a substance use behavior that remains prevalent on college campuses. As theory can guide research and practice, we provide a systematic review of the college-based IUPS epidemiological literature guided by one ecological framework, the theory of triadic influence (TTI). We aim to assess…
