Agreed. I have built a tolerance to it before but know that I do not have ADHD. My friend who certainly does reacts to adderall differently than I do. We have discussed it in detail and seem to be effected differently despite taking similar doses daily. This far beyond my understanding, but ADHD patients appear to have an imbalance between dopamine and norepinephrine in the mesocorticolimbic dopamine pathway and the locus coeruleus-noradrenergic system. There is more to this of course and I'm sure I botched even that part. Regardless, the point is that these medications actually treat their underlying issue instead of overdriving the same systems. Tolerance is mostly irrelevant in this regard as people without ADHD do not have these same differences which means they do not react to the drug in the same manner. Simply put, these medications tend to make ADHD patients more calm and focused and normal people tend to feel "tweaked".
