I don't think Adderall always improves grades. We saw it so many times on psych. A student from other institutions (we can't see our own university students on psych) would come in, the physician would be like how are your grades (including medical students from other places), and the patients would be like they're "ok". Patients also looked like sometime was off. They were unnaturally smiley with a huffiness that just put me on edge.
Also, I've found out close friends of mine have used Adderall in the past and their performance is still the same. All that has changed is they go on long rants on FB every now and then and say **** that they probably wouldn't say if they weren't on adderall. A good example of this is this one guy who I know takes adderall because he's friends with another friend of mine. In a patient safety day we were having he was put on the spot about what human engineering factor he may apply to prevent an a lapse, he rudely shakes his head and made his body language seem like the professor was asking an idiotic question. Then he blurted out that he would load the doctor who made the mistake on Adderall in front of the whole class including attending physicians and seemed to not regret it. I thought I knew the guy well during the first year of med school and I felt he was a very genuine, kind person. When I approached him that day and told him I thought his response was stupid, inconsiderate, and the equivalent of blurting out to the class that he was probably using adderall he like literally had no response and kinda mocked me and just made me feel like I was doing a terrible thing by being honest... I was like screw you man. I'm not being real with you anymore.
TL;DR: I think buying adderall from other students instead of being diagnosed with attention deficit and prescribed it is probably not a great idea...
