Drug rehabilitation is sometimes a part of a criminal justice clients court sentence. In order to get these clients the treatment they need, there are a few steps that need to be followed before they can enroll into a drug or alcohol rehabilitation facility. First, they need to find out if they are eligible for drug rehab during their time in the Williamstown, Missouri criminal justice system. Their case is evaluated by a panel who makes the decision if they are in need of rehabilitation and if so how much and what type is necessary. Furthermore, when they are screened for substance abuse problems, the client is also evaluated for mental health problems as well. Their drug addiction problem, mental health concerns, criminal activity, sentence length and previous substance abuse history are all determining variables in the creation of the treatment plan.
