Criminal justice client rehabs can be considered being a considerably better option than jail time or heavy fines for many who have already been convicted of any sort of alcohol or drug related crime. For instance, anyone who has been in prison for driving under the influence of alcohol or drugs may qualify to get treatment services because of their problem instead of serving time in jail. The judge could even order that the individual receive treatment, either alone or in addition to other sentencing. New offenders in particular in many cases are given the chance to choose a criminal justice client rehab rather than other sentencing, and it is highly recommended that they make the most of it if it is an alternative. The idea behind criminal justice client rehabs is it is much more efficient and effective to invest time and effort into rehabilitation than punishment. Much research has been carried out to see how effective this process 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 who experience treatment have a better probability of remaining out of the system following rehabilitation.
