Anecdotally: I never met failing or bottom-barrel students taking ADHD meds to boost their performance. Obviously, I can't know if students from the bottom percentile also engaged in that, but all the students I knew that took drugs to perform better, were motivated students that wanted to maximize their grades. And they studied things that required lots of reading and memorization (law, medicine, and similar). My take was that the kids that used those drugs, were the ones that wanted an extra push on the last 10% - to put it that way.
