My wife is a professional that deals with elementary school kids in Mass for 504's and IEP's (two different ways to service kids with issues - many of them are on drugs of some sort).
I deal with 15-18 years olds in state care, almost all of them on drugs for various issues. About 1/2 are being treated for ADHD.
