Criminal justice client rehabs can be considered as being a considerably better option than incarceration or significant fines for those who have already been convicted of any kind of drug or alcohol related crime. For example, anyone who has been in prison for dui of alcohol or drugs may be eligible to receive rehabilitation services for his or her problem instead of serving time in jail. The judge could even order that the individual receive rehabilitation, either alone or together with other sentencing. New offenders in particular tend to be given the chance to select a criminal justice client rehab as opposed to other sentencing, and it is well-advised they benefit from it if it's an option. The idea behind criminal justice client rehabs is that it is far more efficient and effective to invest time and energy into rehab than enforcement of other consequences. Much research has been carried out 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 rehabilitation. The signs and indicators seem to be quite positive, and criminal justice clients who take part in treatment have better chance of remaining out of the judicial system following rehabilitation.
