Criminal justice client rehabs can be considered as being a significantly 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, somebody who has been found guilty of driving under the influence of alcohol or drugs may qualify to obtain rehabilitation services because of their problem instead of serving time in prison. The judge may even order that the individual receive treatment, either alone or along with other consequences. Very first time offenders in particular in many cases are given the chance to choose a criminal justice client rehab instead of other sentencing, and it is highly recommended that they reap the benefits of it if it is a possibility. The concept behind criminal justice client rehabs is that it is much more efficient and effective to invest time and effort into rehab than enforcement of other consequences. Much research has been done to see how effective this method is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehab. All indicators appear to be quite positive, and criminal justice clients who do experience rehabilitation have better probability of remaining out of the system following rehab.
