Drug rehabilitation is sometimes a part of a criminal justice clients sentence for the crime they have committed. In order to get these clients the rehabilitation they need, there are a few specific steps that should be followed before they can enroll into a drug or alcohol rehab program. First, they need to determine if they are eligible for drug treatment while involved in the Belmont, 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 necessary. Additionally, when the client is screened for substance abuse problems, the client is also screened for mental health problems as well. Their drug addiction problem, mental health issues, criminal activity, sentence length and previous substance abuse history are all determining variables in the creation of the rehabilitation plan.
