Criminal justice client rehabs can be considered as being a considerably better option than jail time or heavy fines for many who have been convicted of any type of drug or alcohol related crime. For example, somebody who has been in prison for dui of drugs or alcohol may be eligible to receive rehabilitation services for problem rather than serving time in prison. The judge might even order the individual receive treatment, either alone or together with other consequences. New offenders in particular in many cases are given the ability to select a criminal justice client rehab as opposed to other sentencing, and it is highly recommended that they make the most of it if it is an alternative. The theory behind criminal justice client rehabs is that it is much more effective and efficient to invest commitment into treatment than enforcement of other consequences. Much research has been done to discover how effective this process is on recidivism rates, i.e. if the individual returns or not to criminal justice system following treatment. The signs and indicators seem to be quite positive, and criminal justice clients who take part in treatment have a better potential for remaining out of the judicial system following treatment.
