Criminal justice client rehabs are available as a significantly better option than prison time or heavy fines for those who have been convicted of any sort of drug or alcohol related crime. For example, a person who has been in prison for driving under the influence of drugs or alcohol may qualify to receive rehabilitation services because of their problem as opposed to serving time in prison. The judge could even order the individual receive rehab, either alone or together with other consequences. First-time offenders specifically in many cases are given the chance to select a criminal justice client rehab as opposed to other sentencing, and it is highly recommended that they benefit from it if it's a possibility. The concept behind criminal justice client rehabs is that it is way more effective and efficient to invest time and energy into rehabilitation than enforcement of other consequences. Much research has been completed to observe how effective this approach is on recidivism rates, i.e. if the individual returns or not to criminal justice system following treatment. The signs and indicators appear to be quite positive, and criminal justice clients that experience rehabilitation have better potential for remaining out of the system following rehabilitation.
