Criminal justice client rehabs can be considered as a significantly better option than prison time or significant fines for those who have been convicted of any type of alcohol or drug related crime. For instance, a person who has been in prison for driving while impaired of alcohol or drugs may qualify for rehabilitation services because of their problem instead of serving time in prison. The judge might order the individual receive rehab, either alone or in addition to other consequences. First-time offenders in particular are often given the chance to choose a criminal justice client rehab instead of other sentencing, and it is highly recommended they benefit from it when it is a possibility. The theory behind criminal justice client rehabs is that it is much more efficient and effective to invest commitment into rehab than enforcement of other consequences. Much research has been carried out to find out how effective this strategy 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 experience treatment have better chance of remaining out of the judicial system following treatment.
