Drug treatment is sometimes a part of a criminal justice clients sentence for the crime they have committed. In order to get these individuals the rehabilitation they need, there are some steps that need to be followed before they can enroll into a drug or alcohol treatment facility. First, they need to determine if they are eligible for drug treatment while involved in the Granville, Massachusetts criminal justice system. Their case is reviewed by a panel who makes the decision if they are in need of treatment and if so how much and what type is necessary. Additionally, when they are evaluated for drug addiction problems, the client is also evaluated for mental health problems as well. Severity of addiction, mental health problems, criminal activity, sentence length and previous substance abuse history are all determining variables in the creation of the rehabilitation plan.
