The ability of ritalin to help hyper-people to calm down and
focus, though it is actually a stimutlant, has resulted in my opinion the strangest drug myth:
snorting ritalin will allow you to study better
This idea is especially popular in the New England Bording School Circuit, probably 'cause on any given dorm you're sure to find at least three kids with a prescription.
Aside: It is actually kinda ironic to watch someone who you know (and who you know has been having a good time of it) start doing drugs to get back to a proverbial level playing field.
I actually have done this once in college... for strictly legitimate research purposes... er... you understand...
anyway, I was able to pump out a 17 page paper on Hiedegger in about six hours one night, so maybe it isn't such a myth.
