Criminal justice client rehabs can be considered as a considerably better option than prison time or heavy fines for those who have already been convicted of any kind of alcohol or drug related crime. For example, somebody who has been in prison for driving drunk of drugs or alcohol may be eligible to get rehabilitation services for their problem rather than serving time in jail. The judge could even order that the individual receive treatment, either alone or together with other sentencing. New offenders in particular are often given the chance to select a criminal justice client rehab as opposed to other sentencing, and it is well-advised they make the most of it if it is an option. The concept behind criminal justice client rehabs is that it is far more efficient and effective to invest time and effort into rehab than enforcement of other consequences. Much research has been completed to discover how effective this approach is on recidivism rates, i.e. if the individual returns or not to criminal justice system following treatment. All indicators appear to be quite positive, and criminal justice clients that do take part in rehab have a much better chance of remaining out of the judicial system after rehab.
