Drug treatment is sometimes a part of a criminal justice clients sentence for the crime they have committed. In order to provide these clients the rehabilitation they need, there are some specific steps that need to be followed before they can enroll into a drug or alcohol rehab center. First, they need to find out if they are eligible for drug rehab during their time in the Warren, Massachusetts 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 required. Furthermore, when they are evaluated for drug addiction problems, the client is also evaluated for mental health issues as well. Severity of addiction, mental health concerns, criminal activity, sentence length and previous treatment history are all determining variables in the creation of a criminal justice treatment plan.
