Criminal justice client rehabs are available as being a considerably better option than jail time or heavy fines for those who have 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 qualify to obtain rehab services because of their problem as opposed to serving time in jail. The judge might even order that the individual receive treatment, either alone or together with other sentencing. First time offenders specifically tend to be given the opportunity to select a criminal justice client rehab rather than other sentencing, and it is well-advised they take advantage of it if it's an alternative. The idea behind criminal justice client rehabs is that it is way more effective and efficient to invest time and energy into rehabilitation than punishment. Much research has been carried out to discover 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 who do take part in rehabilitation have a better chance of remaining out of the system after rehabilitation.
