Criminal justice client rehabs are available being a considerably better option than incarceration or heavy fines for individuals who have already been convicted of any type of alcohol or drug related crime. For instance, somebody who has been in prison for driving under the influence of drugs or alcohol may be eligible for rehab services for their problem as opposed to serving time in jail. The judge could even order that the individual receive rehab, either alone or together with other consequences. First-time offenders specifically will often be given the ability to choose a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended that they make the most of it when it is a possibility. The concept behind criminal justice client rehabs is it is much more efficient and effective to invest time and energy into rehab than punishment. Much research has been done to find out how effective this approach is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehab. The signs and indicators seem to be quite positive, and criminal justice clients who experience treatment have a better possibility of remaining out of the system after treatment.
