This is a great place for these types of questions. It's been discussed before here quite a bit - http://searchyc.com/search/yc http://searchyc.com/search/yc is down now or I could offer a few links. I don't consider Adderall/Ritalin/Concerta "performance-enhancing drugs" if you have ADHD. The way my son's doctor explained was great: having ADHD is sort of like having 20/60 vision. If you have 20/60 vision, you need glasses to be able to focus. Kids with ADHD need help focusing in exactly the same way and that's where the drugs come in. Now, there are several performance-enhancing drugs that I've seen people talk about here but I can't remember them. Sorry.
