Criminal justice client rehabs can be considered like a considerably better option than prison time or significant fines for individuals who have been convicted of any sort of alcohol or drug related crime. By way of example, a person who has been in prison for driving while impaired of alcohol or drugs may be eligible to obtain rehab services for their problem instead of serving time in prison. The judge might even order the individual receive rehab, either alone or in addition to other sentencing. New offenders specifically in many cases are given the ability to go with a criminal justice client rehab as opposed to other sentencing, and it is well-advised that they benefit from it when it is a choice. The theory behind criminal justice client rehabs is that it is far more efficient and effective to invest time and effort into treatment than enforcement of other consequences. Much research has been done to observe how effective this approach is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehab. The signs and indicators seem to be quite positive, and criminal justice clients who do take part in treatment have a much better possibility of remaining out of the system after rehab.
