College-age guys who abuse amphetamines such as
ritalin, adderall, and
dexedrine, not for the ADHD-benefit, but for euphoria, the high, and increased sexual stimulation. These "speed fiends" also crave meth, pseudoephedrine, caffeine,
ephedrine, often cocaine, and any other "upper" they can get their hands on.
Jed is a big-time
speed fiend. He snorted 200 mg of
adderall a day for an entire week, spent the entire time jerking off, and then he ran out. He wound up buying
ritalin (even though he can't stand it compared to adderall), just so he could continue the amphetamine high for another week.
