All police officers in New Jersey are now subject to random drug-testing under a directive from the state's new attorney general.

Police departments are also required to implement "early warning systems" triggered by problem behavior such as misconduct accusations, lawsuits, domestic abuse and drunken driving under a separate directive announced by state Attorney General Gurbir Grewal's office.

Grewal, who was appointed by Gov. Phil Murphy in January, said Tuesday that most police departments and county prosecutors already have such policies in place. The two new directives would mandate them statewide.

Under the new rules, every state, county and local law enforcement agency is required to conduct one random drug screening in 2018 and perform such tests twice a year going forward.

Departments are required to report any failed tests -- or officers who refuse a test -- as well as any resulting discipline to the county prosecutor or other supervising agency, reports.
