There is a documentary on Netflix called "Take your pills" about Aderall (and it's cousin Ritalin). According to it a lot of people under 25 take it, they feature a student, a software developer, a financial analyst.
After watching it my understanding of Aderall is that it makes you capable of intense focus (a sort of anti-procrastinator). It doesn't make you smarter or capable of solving stuff that you couldn't before. They end with saying that it destroys lives and that it's dangerous, but they never quite delivered on that, one guy said that it destroyed his life but he never went into detail and he didn't look like you typical image of a crack-addict (ie: felt to me more of like a thing they did to prevent them being accused of promoting drugs).
