Criminal justice client rehabs are available as a far better option than jail time or significant fines for those who have been convicted of any sort of drug or alcohol related crime. By way of example, somebody who has been found guilty of driving under the influence of alcohol or drugs may be eligible for treatment services for their problem instead of serving time in prison. The judge could even order that the individual receive rehabilitation, either alone or together with other sentencing. First-time offenders in particular will often be given the chance to choose a criminal justice client rehab instead of other sentencing, and it is well-advised they benefit from it if it is a choice. The concept behind criminal justice client rehabs is it is far more effective and efficient to invest effort and time into rehab than enforcement of other consequences. Much research has been carried out to see how effective this approach is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehabilitation. All indicators seem quite positive, and criminal justice clients that take part in rehab have better chance of remaining out of the judicial system after treatment.
