Drug or alcohol treatment is sometimes a part of a criminal justice clients sentence for the crime they have committed. In order to get these clients the treatment they need, there are some specific steps that should be followed before they can enroll into a drug rehabilitation center. First, they need to determine if they are eligible for drug rehab during their time in the Waltham, Massachusetts criminal justice system. Their case is reviewed by a panel who decides if they are in need of treatment and if so how much and what type is necessary. Furthermore, when the client is evaluated for drug addiction problems, the client is also evaluated for mental health issues as well. Severity of addiction, 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.
