Criminal justice client rehabs can be considered being a far better option than incarceration or heavy fines for those who have been convicted of any sort of alcohol or drug related crime. For example, someone who has been in prison for driving while impaired of alcohol or drugs may qualify to receive treatment services because of their problem instead of serving time in jail. The judge may even order that the individual receive rehabilitation, either alone or in addition to other consequences. Very first time offenders specifically will often be given the ability to select a criminal justice client rehab as an alternative to other sentencing, and it is well-advised they take advantage of it when it is a possibility. The idea behind criminal justice client rehabs is it is much more effective and efficient to invest commitment into rehabilitation than enforcement of other consequences. Much research has been completed 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. All indicators appear to be quite positive, and criminal justice clients who take part in treatment have better possibility of remaining out of the system following rehab.
