Drug or alcohol rehabilitation is sometimes a part of a criminal justice clients court sentence. In order to provide these clients the treatment they need, there are a few steps that need to be followed before they can enroll into a drug treatment facility. First, they need to find out if they are eligible for drug rehab while involved in the Nashville, Illinois criminal justice system. Their case is reviewed by a panel who decides if they are in need of drug treatment services and if so how much and what type is required. Furthermore, when they are screened for substance abuse problems, the client is also evaluated for mental health issues as well. Severity of addiction, mental health problems, criminal activity, sentence length and previous treatment history are all determining variables in the creation of a criminal justice treatment plan.
