The bill, which now heads to Gov. Chris Christie's desk, calls on the state's Children and Families Department to develop the plan, aided by the Health and Senior Services Department and the New Jersey Youth Suicide Prevention Advisory Council.
Officials would then use the plan to promote greater public awareness about youth suicide prevention services and resources. They also would seek to eliminate problems that hamper access to mental health and substance abuse services.
The state Senate approved the bill by a 36-0 voter earlier this month. The Assembly gave its approval in May.
It's not known when or if Christie will act on the measure.
