Criminal justice client rehabs can be considered as being a considerably better option than prison time or heavy fines for those who have been convicted of any sort of drug or alcohol related crime. For example, anyone who has been in prison for dui of drugs or alcohol may be eligible to receive rehab services for problem instead of serving time in jail. The judge might order that the individual receive rehab, either alone or together with other sentencing. First time offenders in particular are often given the chance to select a criminal justice client rehab instead of other sentencing, and it is highly recommended that they take advantage of it if it is an alternative. The idea behind criminal justice client rehabs is it is much more effective and efficient to invest commitment into rehabilitation 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 quite positive, and criminal justice clients who do experience rehabilitation have better possibility of remaining out of the judicial system following rehab.
