Criminal justice client rehabs can be considered as a significantly better option than jail time or heavy fines for those who have been convicted of any kind of alcohol or drug related crime. As an example, someone who has been found guilty of driving while impaired of drugs or alcohol may be eligible to get rehabilitation services because of their problem as opposed to serving time in prison. The judge may even order the individual receive treatment, either alone or as well as other sentencing. First time offenders in particular in many cases are given the chance to select a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended they benefit from it if it is a possibility. The theory behind criminal justice client rehabs is it is much more effective and efficient to invest time and energy into rehab than enforcement of other consequences. Much research has been done to observe how effective this approach 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 who do experience rehabilitation have a much better probability of remaining out of the system following rehabilitation.
