Drug rehabilitation is sometimes a part of a criminal justice clients court sentence. In order to provide these individuals the treatment they need, there are a few specific steps that need to be followed before they can enroll into a drug or alcohol rehabilitation center. First, they need to find out if they are eligible for drug rehab during their time in the Mason, Illinois criminal justice system. Their case is evaluated by a panel who makes the decision if they are in need of rehabilitation and if so how much and what type is necessary. Furthermore, when the client is screened for drug addiction problems, the client is also evaluated for mental health issues as well. Their drug addiction problem, mental health issues, criminal activity, sentence length and previous substance abuse history are all determining factors in the creation of a criminal justice treatment plan.
