Criminal justice client rehabs are available being a far better option than jail time or heavy fines for many who have already been convicted of any sort of alcohol or drug related crime. For example, a person who has been in prison for driving under the influence of drugs or alcohol may be eligible to get rehabilitation services for problem rather than serving time in prison. The judge might even order that the individual receive treatment, either alone or along with other consequences. New offenders specifically are often given the opportunity go with a criminal justice client rehab instead of other sentencing, and it is highly recommended that they take advantage of it if it is a possibility. The concept behind criminal justice client rehabs is that it is far more efficient and effective to invest effort and time into treatment than punishment. Much research has been done to observe how effective this strategy is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehab. All indicators seem to be quite positive, and criminal justice clients who do experience treatment have a better potential for remaining out of the system after treatment.
