Criminal justice client rehabs are available being a significantly better option than prison time or heavy fines for those who have already been convicted of any sort of drug or alcohol related crime. For example, somebody who has been in prison for driving under the influence of drugs or alcohol may be eligible to receive rehabilitation services for their problem rather than serving time in prison. The judge might even order that the individual receive treatment, either alone or together with other consequences. Very first time offenders in particular will often be given the opportunity choose a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended they make the most of it if it's a possibility. The idea behind criminal justice client rehabs is it is much more effective and efficient to invest time and effort into treatment than enforcement of other consequences. Much research has been done to see how effective this approach is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehab. The signs and indicators seem to be quite positive, and criminal justice clients that do take part in rehabilitation have a much better probability of remaining out of the judicial system following rehabilitation.
