Criminal justice client rehabs can be considered as a far better option than jail time or heavy fines for individuals who have already been convicted of any sort of drug or alcohol related crime. As an example, a person who has been in prison for driving while impaired of drugs or alcohol may be eligible to receive treatment services because of their problem instead of serving time in jail. The judge might order that the individual receive rehabilitation, either alone or as well as other sentencing. First-time offenders in particular tend to be given the opportunity to pick a criminal justice client rehab as an alternative to other sentencing, and it is well-advised they reap the benefits of it if it is an option. The theory behind criminal justice client rehabs is it is far more efficient and effective to invest time and effort into rehab than enforcement of other consequences. Much research has been completed 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 treatment have a much better possibility of remaining out of the judicial system after rehab.
