New Jersey has joined forces with three other Northeastern states to collaborate in investigations of heroin trafficking that often cross state lines. The four-state coalition includes Pennsylvania, New York, Massachusetts and New Jersey, and is expected to attract other states. According to New York Attorney General Eric Schneiderman, 98 percent of his state’s large-scale heroin trafficking cases have involved drugs moving among the four states. Traffickers have been able to avoid prosecution by crossing jurisdictions. According to the attorneys general of the four states, New York City and Philadelphia are the two primary points for heroin trafficking in the Northeast.
