"Current addicts" are known as wireheads. Such a person has had a wire surgically implanted on the back of their head connecting directly with the pleasure center of the brain. Using a transformer (droud), a wirehead plugs himself into a current source and directly stimulates the brain's pleasure center, bringing uncontrolled bliss.[1][2]
