Criminal justice client rehabs can be considered being a considerably better option than prison time or significant fines for those who have already been convicted of any sort of drug or alcohol related crime. For example, anyone who has been in prison for driving under the influence of drugs or alcohol may qualify to get treatment services for their problem as opposed to serving time in prison. The judge might even order that the individual receive rehab, either alone or in addition to other sentencing. First time offenders specifically in many cases are given the chance to select a criminal justice client rehab as an alternative to other sentencing, and it is well-advised they take advantage of it if it's a possibility. The concept behind criminal justice client rehabs is that it is much more efficient and effective to invest time and energy into rehab than enforcement of other consequences. Much research has been carried out to discover how effective this method is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following treatment. All indicators appear to be quite positive, and criminal justice clients that experience treatment have a better probability of remaining out of the judicial system after rehab.
