Criminal justice client rehabs can be considered like a considerably better option than jail time or heavy fines for many who have already been convicted of any type of drug or alcohol related crime. For example, somebody who has been in prison for driving while impaired of drugs or alcohol may be eligible for treatment services because of their problem instead of serving time in jail. The judge may even order the individual receive treatment, either alone or along with other sentencing. First-time offenders specifically tend to be given the opportunity to go with a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended they make the most of it when it is a possibility. The idea behind criminal justice client rehabs is that it is much more efficient and effective to invest time and energy into rehab than enforcement of other consequences. Much research has been carried out to observe how effective this approach is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following treatment. The signs and indicators appear to be quite positive, and criminal justice clients that do take part in rehab have a better potential for remaining out of the judicial system following rehab.
