Criminal justice client rehabs are available as being a significantly better option than jail time or heavy fines for those who have already been convicted of any type of alcohol or drug related crime. As an example, anyone who has been found guilty of driving while impaired of drugs or alcohol may qualify to receive rehab services for his or her problem rather than serving time in jail. The judge might even order that the individual receive rehab, either alone or in addition to other sentencing. Very first time offenders specifically in many cases are given the ability to select a criminal justice client rehab rather than other sentencing, and it is well-advised that they make the most of it when it is a possibility. The theory behind criminal justice client rehabs is that it is much more efficient and effective to invest time and effort into rehabilitation than punishment. Much research has been done to see how effective this process is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehab. All indicators appear to be quite positive, and criminal justice clients that experience rehabilitation have better possibility of remaining out of the system following rehab.
