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