title: Licit and illicit use of medications for Attention-Deficit Hyperactivity Disorder in undergraduate college students.
abstract: OBJECTIVE
  The authors studied the relationship between a diagnosis of Attention-Deficit Hyperactivity Disorder (ADHD), grade point average (GPA), and licit and illicit drug use.
  
  
  METHODS
  They obtained survey data from a convenience sample of undergraduates in a large southern public university.
  
  
  RESULTS
  Among 1,550 respondents, 163 (10.5%) reported an ADHD diagnosis (ADHD Group). Of those without an ADHD diagnosis, 591 (43%) reported using prescription stimulants illicitly (No ADHD, Illicit Use group), and 794 (57%) reported not using prescription drugs illicitly (No ADHD, No Illicit Use group). The GPA of the ADHD group was significantly lower than the GPA of the other 2 groups. The ADHD group and the No ADHD, Illicit Use group reported significantly greater use of all other drugs than did the No ADHD, No Illicit Use group.
  
  
  CONCLUSIONS
  Drug use was associated with a lower GPA in ADHD-diagnosed students than in students without ADHD.
