Drug rehabilitation is sometimes a part of a criminal justice clients sentence for the crime they have committed. In order to get these individuals the treatment they need, there are some steps that should be followed before they can enroll into a drug or alcohol treatment center. First, they need to find out if they are eligible for drug treatment while involved in the Trilla, Illinois criminal justice system. Their case is evaluated by a panel who decides if they are in need of rehabilitation and if so how much and what type is necessary. Furthermore, when they are evaluated 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.
