Criminal justice client rehabs are available being a far better option than prison time or significant fines for those who have already been convicted of any kind of alcohol or drug related crime. As an example, somebody who has been in prison for driving while impaired of drugs or alcohol may be eligible to obtain treatment services because of their problem rather than serving time in jail. The judge might even order that the individual receive treatment, either alone or in addition to other consequences. First-time offenders in particular in many cases are given the opportunity to select a criminal justice client rehab instead of other sentencing, and it is highly recommended that they make the most of it if it's an option. The idea behind criminal justice client rehabs is that it is far more efficient and effective to invest time and effort into rehab than enforcement of other consequences. Much research has been carried out to see how effective this process is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehabilitation. The signs and indicators seem to be quite positive, and criminal justice clients who experience rehabilitation have a better potential for remaining out of the judicial system following treatment.
