When I went to CU Adderall was everywhere. I knew kids that snorted it to party, used it to stay up for 4 days straight during finals and even chilled with a guy once that literally didnt sleep at all during the week then slept all day Sunday. I even saw a kid literally fall asleep on his feet during a class presentation because he had been up for a few days on that stuff. One of the most messed up things I have seen was a kid desperately try to take a resin hit by lighting the end of his bong bowl and sucking in butane because he was too wigged out from taking Adderall and playing guitar hero for hours. Seriously fuck that stuff. You dont need it to study, just manage your time so you are not cramming all night before tests and you are good.
