100% disagree I have worked with co-workers who took a lot of adderall due to tolerance and they had to be terminated because they had meth like rageouts. Don't kid yourself, Adderall is an amphetamine just like meth is.
A hallmark of "real ADD" is that tolerance typically doesn't build. Once you are at an appropriate dose you can stay there. The treatment is supposed to reduce inattentiveness and improve focus. If abused or used recreationally, it has the opposite effect, to stimulate and enhance mood, to create a kind of manic energy. I've been at the same dose for over 7 years with no noticeable tolerance.
