Criminal justice client rehabs can be considered being a far better option than jail time or significant fines for those who have been convicted of any sort of drug or alcohol related crime. For example, someone who has been in prison for driving under the influence of drugs or alcohol may qualify to get treatment services for his or her problem as opposed to serving time in prison. The judge might order the individual receive rehabilitation, either alone or together with other sentencing. First-time offenders specifically are often given the opportunity go with a criminal justice client rehab as opposed to other sentencing, and it is well-advised they make the most of it when it is a choice. The idea behind criminal justice client rehabs is that it is way more efficient and effective to invest time and effort into rehabilitation than punishment. Much research has been completed to discover how effective this method is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following treatment. The signs and indicators seem to be quite positive, and criminal justice clients who do experience rehabilitation have better chance of remaining out of the judicial system after treatment.
