Criminal justice client rehabs are available as being a considerably better option than time in jail or heavy fines for individuals who have already been convicted of any kind of alcohol or drug related crime. For instance, someone who has been in prison for dui of drugs or alcohol may be eligible to receive rehab services because of their problem as an alternative to serving time in prison. The judge might even order the individual receive rehab, either alone or together with other sentencing. New offenders specifically will often be given the ability to pick a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended that they benefit from it if it is a choice. The theory behind criminal justice client rehabs is it is way more effective and efficient to invest time and effort into rehabilitation than punishment. Much research has been done to observe 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 that take part in rehab have a much better possibility of remaining out of the system after treatment.
