It's a stimulant. I have no doubt that someone's found a way to abuse it. But for me, I can't for the life of me imagine why anyone would want to. Other drugs like coffee or beer are much more pleasant. If I realize I forgot to take my daily Adderall, oops! Guess I might not get as much work done today as I'd planned, but not to the point where I'd go back home to get it, and I certainly wouldn't feel a craving or desire to.
