Criminal justice client rehabs can be considered being a far better option than incarceration or heavy fines for those who have already been convicted of any type of alcohol or drug related crime. For example, a person who has been in prison for driving while impaired of alcohol or drugs may be eligible to receive rehab services for their problem as opposed to serving time in prison. The judge could even order the individual receive treatment, either alone or as well as other consequences. Very first time offenders specifically will often be given the ability to choose a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended they take advantage of it if it is a possibility. The concept behind criminal justice client rehabs is it is far more effective and efficient to invest commitment into rehabilitation than enforcement of other consequences. Much research has been done to observe how effective this strategy is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehabilitation. All indicators seem to be quite positive, and criminal justice clients who experience rehab have better chance of remaining out of the judicial system after treatment.
