There are some weird causation conclusions in that article. From my experience, stimulant proliferation in university is largely dependent on your social circle. Adderall was passed around freely in my fraternity and some of my circles. Have a test coming up? Pop a stimulant like it's nothing. Yet I was in other circles (squareish students) where the individuals weren't really exposed to stimulants much less the mentality of flippantly popping them under academic stress. They wouldn't really know where to get them, either. In other words, I have a problem with drawing a conclusion of stim effectiveness from demographics and their respective grades. I don't know anyone who wouldn't consider amphetamine effective for buckling down and burning through some work. You don't need to have ADD to benefit from a flood of dopamine.
