Criminal justice client rehabs are available as a considerably better option than time in jail or heavy fines for those who have been convicted of any sort of drug or alcohol related crime. By way of example, anyone who has been in prison for driving under the influence of alcohol or drugs may qualify to obtain rehabilitation services for their problem instead of serving time in jail. The judge may even order that the individual receive rehab, either alone or in addition to other consequences. First-time offenders specifically in many cases are given the ability to go with a criminal justice client rehab as an alternative to other sentencing, and it is well-advised that they benefit from it when it is an alternative. The idea behind criminal justice client rehabs is that it is way more efficient and effective to invest effort and time into rehabilitation than enforcement of other consequences. 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. All indicators seem quite positive, and criminal justice clients who do take part in rehab have a better possibility of remaining out of the system after rehab.
