Abstract
Methylphenidate (MPH) has a long history of being an effective medication for attention deficit/hyperactivity disorder (ADHD). Recently, the nonmedical use of MPH has increased, particularly among college students. To investigate this, we surveyed 2,087 students regarding MPH misuse. Of 2,087 respondents, 110 (5.3%) used MPH nonmedically at least once. Most obtained MPH free from a friend, acquaintance, or family member. Misuse of Ritalin® occurred four times more frequently than Concerta.® Among Ritalin abusers, Intranasal use was reported more often than oral. Students reported using MPH nonmedically for recreational reasons as well as to improve academic performance.
