Criminal justice client rehabs are available as a significantly better option than time in jail or significant fines for those who have been convicted of any type of drug or alcohol related crime. By way of example, someone who has been in prison for driving under the influence of drugs or alcohol may qualify for rehabilitation services for problem rather than serving time in prison. The judge may even order that the individual receive treatment, either alone or as well as other sentencing. Very first time offenders specifically in many cases are given the opportunity pick a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended they take advantage of 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 treatment than enforcement of other consequences. Much research has been done to find out how effective this method is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following treatment. All indicators seem quite positive, and criminal justice clients who do take part in rehabilitation have a much better chance of remaining out of the judicial system after treatment.
