the fancy term for "borrowing some adderall from your bro before the big test" I suppose. aka "brain doping"
There was a really disturbing article in Wired last year about which drugs are best for brain doping and how to fake symptoms to trick your doctor into giving them (since, most of the time, doctors prescribe this stuff based on your input and not for any observable problems.) It was the most shameless thing I've ever read in a major magazine and in such a sickeningly upbeat and perky tone (like a lot of their articles), while telling readers that they should probably do this if they want a leg up on the competition.
