Inside Higher Ed, Dec. 15. A recent study led by David Rabiner, associate research professor and director of undergraduate studies in the Department of Psychology and Neuroscience, found that 8.9 percent of Duke and UNC-Greensboro students had used the ADHD drugs Ritalin and Adderall without a prescription during college. Students mainly used the drugs for academic purposes, desiring to study longer or better. Other researchers on the project were from Duke (E. Jane Costello, professor of medical psychology and H. Scott Swartzwelder, clinical professor of psychiatry and psychology/neuroscience), UNC-Greensboro and the University of Michigan.
