A northern New Jersey school district has adopted a voluntary random drug testing program for middle school students.

Parental consent is required for sixth, seventh, and eighth grade students in the Belvidere school district. Parents must also pay for the cost of the treatment program.

Those who test positive will be required to attend an early intervention program and visit a guidance counselor or nurse at least six times.

Superintendent Dirk Swaneveld told The Express-Times of Easton, Pa., hopefully the program "works as a deterrent and to help kids."

Belvidere High School has had random drug testing for athletes and students in extracurricular activities since 2008.
