Criminal justice client rehabs can be considered as a significantly better option than incarceration or significant fines for many who have already been convicted of any kind of drug or alcohol related crime. For instance, a person who has been in prison for dui of drugs or alcohol may be eligible to obtain rehab services because of their problem as an alternative to serving time in prison. The judge may even order the individual receive treatment, either alone or in addition to other consequences. First time offenders specifically are often given the ability to select a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended that they make the most 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 time and effort into rehabilitation than enforcement of other consequences. Much research has been completed to see how effective this strategy is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehab. All indicators appear to be quite positive, and criminal justice clients that take part in rehabilitation have a much better chance of remaining out of the system following treatment.
