The amount of methylphenidate manufac- tured has increased sharply in the 1990s. From 1990 through 2000, the production of methylphenidate in the United States grew by 800% (Wen 2000).9 One national survey of physicians' diagnoses, based on 1993 data, found that of the 1.8 million persons receiving medications for ADHD, 1.3 million were taking methylphenidate (cited in Diller 1996, p. 12).
