Five people were sentenced to state prison, the latest members of a Jersey City, N.J.-based drug ring that trafficked prescription pain pills in Hudson, Monmouth, Morris, Ocean and Bergen counties, according to the New Jersey Attorney General’s Office.

Fifteen defendants have pleaded guilty for their roles in a black-market prescription narcotic drug ring that involved Medicaid being billed for phony doctor visits and medicines never dispensed.

Two rings of alleged drug dealers, including several doctors and pharmacists, were arrested in connection with the black-market distribution in New Jersey of thousands of prescription pain pills, many of which were paid for through Medicaid and private insurance.
