Unlike in America where its a good word... in Ireland a dope is someone who is very stupid - an eejit in other words. It never ever means good unless your a D4 wannabe(they think there posh *roysh*). And you dont really wanna be one of them dopes. Haaaa. Basically anyone who is thick is a dope especially if what they do or say is funny for you but not for them. And in Ireland dope it is NEVER used in reference to drugs - heroin is 'gear' and weed is 'green'. If you asked someone for dope they would look at ye sideways and laugh and ask if you thought you were American...

short for dopamine, which is actually a chemical realeased in yoru brain, when something "good" happens. Dopamine is realeased when you eat, and deppending on the content of what you consume certain amounts of dopamine realease.

Also this is realeased in sex, when you see or get something you like, like a gold watch, or when you have a good "trip" hence "DOPE" is used to describe certain drugs.
