Drug rehabilitation is sometimes a part of a criminal justice clients court sentence. In order to provide these individuals 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 rehab during their time in the Mode, Illinois 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 required. Additionally, when they are screened for substance abuse problems, the client is also evaluated for mental health issues 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 rehabilitation plan.
