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