Criminal justice client rehabs are available being a considerably better option than jail time or heavy fines for individuals who have already been convicted of any sort of drug or alcohol related crime. For example, somebody who has been in prison for driving drunk of alcohol or drugs may be eligible to obtain rehabilitation services because of their problem instead of serving time in prison. The judge could even order that the individual receive rehab, either alone or as well as other consequences. First time offenders in particular are often given the opportunity to pick a criminal justice client rehab rather than other sentencing, and it is well-advised that they benefit from it if it's a possibility. The theory behind criminal justice client rehabs is it is far more effective and efficient to invest time and effort into treatment than enforcement of other consequences. Much research has been done to discover how effective this method is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehab. All indicators seem to be quite positive, and criminal justice clients that experience rehab have a much better chance of remaining out of the judicial system after rehab.
