Criminal justice client rehabs are available being a far better option than prison time or significant fines for those who have been convicted of any type of alcohol or drug related crime. By way of example, someone who has been in prison for driving while impaired of drugs or alcohol may be eligible for treatment services for problem instead of serving time in jail. The judge might even order that the individual receive rehab, either alone or together with other sentencing. First time offenders specifically will often be given the opportunity to pick a criminal justice client rehab as opposed to other sentencing, and it is well-advised they benefit from it when it is an alternative. The theory behind criminal justice client rehabs is it is much more effective and efficient 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 that take part in treatment have a better potential for remaining out of the system after treatment.
