Criminal justice client rehabs are available as being a significantly better option than time in jail or heavy fines for individuals who have already been convicted of any sort of drug or alcohol related crime. As an example, somebody who has been found guilty of driving drunk of drugs or alcohol may qualify to receive treatment services because of their problem rather than serving time in jail. The judge might order that the individual receive rehabilitation, either alone or in addition to other consequences. First time offenders specifically tend to be given the ability to select a criminal justice client rehab instead of 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 rehab than enforcement of other consequences. Much research has been carried out to find out how effective this process is on recidivism rates, i.e. if the individual returns or not to criminal justice system following treatment. The signs and indicators appear to be quite positive, and criminal justice clients that do experience rehabilitation have a better chance of remaining out of the judicial system following rehab.
