The main aim of this paper is to discuss some moral implications of cognitive doping in education. In this context, the term 'cognitive doping' refers to the use of cognitive enhancing drugs--such as Ritalin--among students in order to improve their cognitive functions and educational performance on college exams. Cognitive doping raises not only…

Dilute guarana´ ("Paullinia cupana") powder aqueous extract is a soft drink that contains three structurally related methylxanthines (MXs), caffeine (CF), theobromine (TB), and theophylline (TP); CF is present in a large excess. Literature data show that values of [lambda][subscript max] and [epsilon][subscript max] of these three MXs…

Sleep deprivation impairs a wide range of cognitive processes, but the precise mechanism underlying these deficits is unclear. One prominent proposal is that sleep deprivation impairs vigilant attention, and that impairments in vigilant attention cause impairments in cognitive tasks that require attention. Here, we test this theory by studying the…

Background: In the USA, lower income minority ethnic children and teenagers report high consumption of sugar sweetened beverages, which cause dental erosion and dental carries, and play a significant role in overweight, obesity and diabetes. Objective: This study aimed to examine urban adolescents' beliefs about sports and energy drinks to…

Objective: This study determined the frequency, reasons for, and side effects of energy drinks (ED) consumption among online students. Participants: Students attending an online university. Methods: Participants were recruited by email and completed a 59-question survey about their prior months ED practices using a combination of validated surveys…

Objective: Stimulant medications are the main treatment for Attention Deficit Hyperactivity Disorder (ADHD), but overall treatment efficacy in adults has less than a 60% response rate. This study aimed to identify neural and cognitive markers predictive of longitudinal improvement in response to stimulant treatment in drug-naïve adults with ADHD.…

Objective: This study examined the prevalence and factors associated with non-medical use of prescription stimulants to promote wakefulness. Participants: We surveyed 3,160 university students aged 18-35 between June 2016 and May 2017. Method: Participants reported whether they used prescription stimulants non-medically to stay awake and completed…

Objective: Stimulant medications are the primary pharmacological intervention for ADHD, yet our understanding of how sex and gender impact stimulant treatment outcomes remains limited. Clinical guidelines do not differ for female and male individuals despite possible sex and gender-related differences in effectiveness, adverse events, and…

Objective: To determine if treatment of co-occurring adult ADHD and Cannabis Use Disorder (CUD) with extended-release mixed amphetamine salts (MAS-ER) would be effective at improving ADHD symptoms and promoting abstinence. Method: A 12-week randomized, double-blind, two-arm pilot feasibility trial of adults with comorbid ADHD and CUD (n = 28)…

Recent research has demonstrated chewing gum can enhance various cognitive processes associated with learning, but most studies have used cognitive functioning tasks (e.g., selective attention and working memory) as outcomes. Across two experiments, we investigated effects of chewing gum on self-reports of alertness and test performance following…

This study tests theories of social learning and strain to explain non-medical prescription drug use (NMPDU) among Latino college students at a Hispanic-Serving Institution (HSI). Logistic regression analyses indicate social learning and negative stressors help explain such usage, while refined models suggest that Latinos use of NMPD is primarily…

Objective: To identify academic factors pertaining to college students, calendar timing, and particular moments that are uniquely associated with elevated likelihood of prescription stimulant misuse (intentions and actual behavior) in daily life. Participants: Participants were 297 freshmen and sophomores at a large public university in the United…

The current study examined the efficacy of health warnings on caffeinated energy drinks (CEDs). Participants aged 12-24 years (n = 2040) completed an online survey where they were asked to recall any existing warning statements on CED products and were randomized to one of 29 experimental warning conditions. Regression models were fitted to…

Introduction: Prescription stimulants are an effective FDA approved treatment for attention deficit hyperactivity disorder (ADHD) however their safety has come under scrutiny. Multiple studies demonstrate safe use in pediatric populations, but prescriptions are increasing to adults and it is not evident which comorbidities might place people at…

Monitoring the Future (MTF) is an ongoing research program conducted at the University of Michigan's Institute for Social Research under a series of investigator-initiated, competing research grants from the National Institute on Drug Abuse beginning in 1975. The integrated MTF study includes annual surveys of nationally representative samples of…
