More information about drug treatment programs law offenders in Avon, New Jersey went through?

I'm writing a pseudo-fiction book about the lives of drug users and pushers here in NJ, and I wonder what happened to them when they were admitted in rehab centers. The information I got from our local health office were not sufficient. Please help me.
