While I am sure there must be SOME inappropriate use of stimulants in our universities, I get the impression it's not nearly to the same degree as what you guys are talking about. ADHD can only be diagnosed and medication prescribed by a specialist here, it's not trivial with a child, it's generally a months long multidisciplinary process with an adult (particularly young adults from what I can see)... Your local doctor can prescribe anti depressants (and anti anxiety meds too I think), but not stimulants.
