Criminal justice client rehabs can be considered like a far better option than jail time or heavy fines for those who have already been convicted of any kind of drug or alcohol related crime. For example, someone who has been in prison for driving under the influence of drugs or alcohol may be eligible to get treatment services for their problem as opposed to serving time in prison. The judge may even order that the individual receive rehabilitation, either alone or as well as other consequences. Very first time offenders specifically tend to be given the opportunity to choose a criminal justice client rehab as an alternative to other sentencing, and it is well-advised they benefit from it when it is an option. The idea behind criminal justice client rehabs is it is far more effective and efficient to invest commitment into rehab than enforcement of other consequences. Much research has been carried out to discover how effective this approach is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehabilitation. The signs and indicators seem to be quite positive, and criminal justice clients that experience treatment have a better possibility of remaining out of the system after rehab.
