Drug treatment is sometimes a part of a criminal justice clients sentence for the crime they have committed. In order to provide these clients the rehabilitation they need, there are some steps that need to be followed before they can enroll into a drug rehab program. First, they need to determine if they are eligible for drug rehab while involved in the Glen Lyn, Virginia 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 evaluated 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 treatment plan.
