Somebody who has been on the methadone maintenance treatment (MMT)program for any period of time over a week.

Methadone is usually mixed with tang at the pharmacies where it is prepared, thus the name 'juice'. Tang isn't juice so the term was probably coined by somebody who themselves is a member of MMT.
"Look at all those filthy juiceheads over there, waiting to see the doctor, smoking thier cigarettes and... Drinking thier... Root-beer and... Snorting thier... Multi-Vitamins..."

Much like the term Gorilla, it derives from the show Jersey Shore where the women are absolutely retarded and think they are clever or something by making up names for their equally stupid male friends.
Snooki: Let's go and gut us some gorillas and Juiceheads!

JWOW: Yeah! I want to be a dumb slut too!

the phrase Gorrilla Juicehead was used by JWOW and Snooki on the MTV show Jersey Shore. JWOW went on to define it as a big guy who loves to hit up the gym and possibly uses steroids. Gorrilla juiceheads must be atleast 6ft tall and weight atleast 250 lbs.
Damn look at those gorrilla juiceheads on the beach
