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