Criminal justice client rehabs can be considered like a significantly better option than time in jail or heavy fines for those who have been convicted of any sort of drug or alcohol related crime. As an example, somebody who has been found guilty of driving under the influence of alcohol or drugs may be eligible to get rehab services for his or her problem as an alternative to serving time in jail. The judge might even order the individual receive treatment, either alone or in addition to other sentencing. First time offenders specifically are often given the opportunity to pick a criminal justice client rehab as an alternative to other sentencing, and it is well-advised they benefit from it if it is an option. The theory behind criminal justice client rehabs is that it is much more efficient and effective to invest time and effort into treatment than enforcement of other consequences. Much research has been carried out to observe how effective this approach is on recidivism rates, i.e. if the individual returns or not to criminal justice system following treatment. The signs and indicators seem quite positive, and criminal justice clients who experience treatment have better chance of remaining out of the system following treatment.
