Criminal justice client rehabs are available as being a far better option than jail time or significant fines for individuals who have already been convicted of any kind of drug or alcohol related crime. For instance, anyone who has been in prison for driving under the influence of alcohol or drugs may be eligible for rehabilitation services for his or her problem instead of serving time in jail. The judge may even order the individual receive rehabilitation, either alone or together with other sentencing. First-time offenders in particular in many cases are given the ability to pick a criminal justice client rehab as opposed to other sentencing, and it is well-advised that they make the most of it if it's a choice. The theory behind criminal justice client rehabs is it is far more effective and efficient to invest effort and time into rehabilitation than enforcement of other consequences. Much research has been carried out to observe how effective this strategy is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehab. All indicators seem quite positive, and criminal justice clients who do experience treatment have a better probability of remaining out of the judicial system after rehabilitation.
