Criminal justice client rehabs can be considered being a significantly better option than jail time or heavy fines for many who have already been convicted of any kind of alcohol or drug related crime. For example, a person who has been found guilty of driving under the influence of drugs or alcohol may be eligible for rehabilitation services for his or her problem as opposed to serving time in jail. The judge may even order the individual receive rehabilitation, either alone or in addition to other sentencing. First-time offenders specifically are often given the ability to select a criminal justice client rehab as opposed to other sentencing, and it is well-advised they benefit from it if it is a choice. The idea behind criminal justice client rehabs is that it is way more efficient and effective to invest effort and time into rehabilitation than punishment. Much research has been carried out 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 treatment. All indicators appear to be quite positive, and criminal justice clients who experience rehabilitation have a better chance of remaining out of the system following rehabilitation.
