I have just adopted an 18 yr old boy who has had trouble in school, mostly academic and minor behavioral. He was diagnosed with ADHD in 2002, and never received treatment. I am taking him to specialists and we intend to treat him with appropriate medication. He is an outstanding athlete, with possibilities of college scholarships, so I want to make sure the medication will not effect his eligibility (banned substance). Do you know if Concerta, Adderall or dexedrine contains substances banned for atheletic sports? Thanks
