I Need to Know How to Find Drug Rehabs in Deptford, New Jersey. Help?

I have to do this for my sister-in-law. My brother just died and this really devastated her. She started doing drugs and just didn’t care about her responsibilities. It was my niece who told me about this. I’m planning on visiting them so that I could talk to her and find a drug rehab for her. Just thought I’d ask here because someone might be able to give me a heads up on where the drug rehabs in Deptford are.
