My doctor prescribed it to me as a teenager because I wanted it to help me "study". All I had to do was say I had trouble concentrating and then I had a script good for 30 20mg pills a month.

Didn't take too long for that to develop into one hell of an addiction before I finally quit cold turkey a few years later. Really fucked up my life for a bit. That stuff is essentially cocaine in pill form. I know some kids really do need it but there are wayyy too many 18-25 year old kids taking it for not the right reasons.
