Criminal justice client rehabs can be considered being a considerably better option than time in jail or heavy fines for those who have already been convicted of any kind of alcohol or drug related crime. For example, a person who has been in prison for dui of drugs or alcohol may be eligible to obtain rehab services for his or her problem instead of serving time in prison. The judge could even order the individual receive rehab, either alone or along with other consequences. Very first time offenders specifically in many cases are given the opportunity to go with a criminal justice client rehab instead of other sentencing, and it is highly recommended they make the most of it when it is an alternative. The concept behind criminal justice client rehabs is it is much more effective and efficient to invest effort and time into rehab than enforcement of other consequences. Much research has been completed to find out how effective this approach is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehab. All indicators seem to be quite positive, and criminal justice clients who experience treatment have a much better probability of remaining out of the judicial system after treatment.
