Drug or alcohol rehabilitation 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 some specific steps that need to be followed before they can enroll into a drug or alcohol rehab program. First, they need to find out if they are eligible for drug rehab while involved in the Huntington, Massachusetts criminal justice system. Their case is evaluated by a panel who determines if they are in need of drug treatment services and if so how much and what type is necessary. Furthermore, when they are screened for drug addiction problems, the client is also screened for mental health issues as well. Severity of addiction, mental health issues, criminal activity, sentence length and previous treatment history are all determining factors in the creation of the rehabilitation plan.
