Criminal justice client rehabs are available as a far better option than prison time or heavy fines for individuals who have been convicted of any type of drug or alcohol related crime. For example, a person who has been in prison for driving drunk of alcohol or drugs may qualify to receive rehab services for their problem rather than serving time in jail. The judge may even order that the individual receive rehab, either alone or as well as other sentencing. First time offenders specifically are often given the ability to pick a criminal justice client rehab as opposed to other sentencing, and it is well-advised they reap the benefits of it when it is a choice. The concept behind criminal justice client rehabs is that it is far more efficient and effective to invest time and energy into rehab than enforcement of other consequences. Much research has been done to observe how effective this approach is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehab. All indicators appear to be quite positive, and criminal justice clients that experience treatment have better chance of remaining out of the judicial system following rehabilitation.
