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