At twenty-one, Berenbaum was working a summer internship with the small Raleigh firm of CoCoGenCo, a producer of specialized biochemicals. CoCoGenCo, as later congressional investigations proved, was actually a front for the California "designer drug" manufacturer and smuggler, Jimmy "Screech" McCarley. McCarley’s agents within CoCoGenCo ran innumerable late-night "research projects" in conditions of heavy secrecy. In reality, these "secret projects" were straight production runs of synthetic cocaine, beta-phenethylamine, and sundry tailored variants of endorphin, a natural antipain chemical ten thousand times more potent than morphine.
