Criminal justice client rehabs can be considered as a considerably better option than jail time or heavy fines for many who have been convicted of any sort of drug or alcohol related crime. For instance, anyone who has been in prison for driving under the influence of drugs or alcohol may qualify to receive treatment services because of their problem instead of serving time in jail. The judge could even order the individual receive rehabilitation, either alone or as well as other consequences. Very first time offenders in particular are often given the opportunity to go with a criminal justice client rehab instead of other sentencing, and it is highly recommended they benefit from it if it is an alternative. The theory behind criminal justice client rehabs is that it is far more efficient and effective to invest time and energy into rehabilitation than punishment. Much research has been done to observe how effective this method 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 quite positive, and criminal justice clients who experience treatment have a much better chance of remaining out of the judicial system after treatment.
