Criminal justice client rehabs are available as a considerably better option than prison time or significant fines for those who have already been convicted of any sort of alcohol or drug related crime. As an example, someone who has been found guilty of driving under the influence of drugs or alcohol may be eligible for treatment services for his or her problem instead of serving time in jail. The judge might even order that the individual receive rehabilitation, either alone or together with other consequences. First time offenders specifically tend to be given the ability to go with a criminal justice client rehab as an alternative to other sentencing, and it is well-advised that they reap the benefits of it when it is an option. The idea behind criminal justice client rehabs is that it is much more efficient and effective to invest time and effort into rehab than punishment. Much research has been carried out to find out how effective this strategy is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following treatment. All indicators seem to be quite positive, and criminal justice clients who do experience treatment have better possibility of remaining out of the system following rehab.
