Criminal justice client rehabs can be considered as a far better option than prison time or significant fines for many who have already been convicted of any kind of alcohol or drug related crime. For example, a person who has been in prison for driving while impaired of drugs or alcohol may qualify for rehabilitation services for problem rather than serving time in jail. The judge may even order that the individual receive rehab, either alone or together with other sentencing. New offenders specifically in many cases are given the opportunity to select a criminal justice client rehab as opposed to other sentencing, and it is highly recommended they benefit from it if 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 treatment than punishment. Much research has been carried out to find out 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 appear to be quite positive, and criminal justice clients who experience rehab have a better potential for remaining out of the system after treatment.
