A report from the Substance Abuse and Mental Health Services Administration indicates that the number of ED visits involving ADHD stimulants increased from 13,379 to 31,244 between 2005 and 2010. The report noted that no significant increases in such visits were observed among children younger than 18. ED visits among patients taking ADHD stimulants for non-medical use increased from 5,212 to 15,585 during the study timeframe. Other pharmaceuticals were involved in 45% of visits and illicit drugs and alcohol were involved in about 20% of visits.
