Speed fiend

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.
