Criminal justice client rehabs can be considered as being a considerably better option than prison time or heavy fines for those who have already been convicted of any kind of drug or alcohol related crime. For instance, anyone who has been in prison for dui of alcohol or drugs may be eligible to obtain treatment services because of their problem rather than serving time in jail. The judge may even order the individual receive rehabilitation, either alone or together with other consequences. Very first time offenders specifically tend to be given the ability to go with a criminal justice client rehab instead of other sentencing, and it is highly recommended they benefit from it when it is a possibility. The theory behind criminal justice client rehabs is that it is much more efficient and effective to invest effort and time into rehabilitation than punishment. Much research has been carried out 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 rehabilitation. All indicators appear to be quite positive, and criminal justice clients that take part in rehab have a much better possibility of remaining out of the judicial system following rehab.
