Criminal justice client rehabs are available like a considerably better option than prison time or heavy fines for those who have been convicted of any sort of alcohol or drug related crime. For instance, someone who has been in prison for driving under the influence of drugs or alcohol may be eligible to receive rehabilitation services because of their problem instead of serving time in jail. The judge might even order the individual receive rehabilitation, either alone or along with other consequences. First-time offenders in particular are often given the chance to pick a criminal justice client rehab as opposed to other sentencing, and it is highly recommended that they benefit from it when it is an option. The theory behind criminal justice client rehabs is that it is way more effective and efficient to invest time and effort into rehab than enforcement of other consequences. Much research has been carried out 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 seem quite positive, and criminal justice clients that experience rehab have a much better chance of remaining out of the judicial system after rehabilitation.
