Criminal justice client rehabs can be considered being a far better option than jail time or significant fines for those who have already been convicted of any sort of alcohol or drug related crime. For instance, a person who has been found guilty of driving while impaired of drugs or alcohol may qualify for treatment services for his or her problem as opposed to serving time in prison. The judge might order the individual receive rehabilitation, either alone or in addition to other sentencing. First-time offenders specifically are often given the opportunity choose a criminal justice client rehab as opposed to other sentencing, and it is highly recommended they benefit from it if it is a choice. The idea behind criminal justice client rehabs is that it is far more efficient and effective to invest effort and time into rehabilitation than enforcement of other consequences. Much research has been carried out to find out how effective this approach is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehabilitation. The signs and indicators seem to be quite positive, and criminal justice clients who do take part in rehab have a much better chance of remaining out of the judicial system following rehabilitation.
