CO-ED Magazine has an interesting article on Adderal. Here's a taster:

Adderall is designed to be used as study tool for students diagnosed with ADD or ADHD, but you don't need to have either diagnosis to feel the desired effects of this drug. It's an amphetamine, so it enhances your attention span and wakes you up, thus helping you pull all-nighters during finals week and just have more stamina for academia in general. Basically, it's like Red Bull. On cocaine. With five iced lattes. But, Adderall is not always used for it's intended medical purpose (shocker!). These pills can also aid in weight loss, making it popular with girls looking for an easy way to shed the pounds. Not only that, but it's used to help people party more effectively. Adderall keeps you awake and sharpens your mind, both allowing you to keep that party goin' a little longer.

My Adderall partying usage has ranged from popping half a pill to invigorate bar-hopping to snorting mass quantities of the stuff with a small group of friends. (The latter is not so fun. Putting anything up your nose is foolish, and Adderall is no exception.) At first it was exciting; your heart beats a million miles a minute and you can't stop talking. Anyone you're having a conversation with instantly becomes your best friend. You get them; they get you. Best of all: it doesn't give you the munchies, and due to the sharpening of the mind, you can drink like a sailor and still keep your composure.
