Drug or alcohol treatment is sometimes a part of a criminal justice clients court sentence. In order to get these clients the treatment they need, there are a few specific steps that need to be followed before they can enroll into a drug rehabilitation program. First, they need to determine if they are eligible for drug rehabilitation while involved in the Irvington, Illinois criminal justice system. Their case is reviewed by a panel who determines if they are in need of treatment and if so how much and what type is needed. Furthermore, when the client is evaluated for substance abuse problems, the client is also evaluated for mental health problems as well. Their drug addiction problem, mental health problems, criminal activity, sentence length and previous treatment history are all determining factors in the creation of a criminal justice treatment plan.
