Criminal justice client rehabs can be considered being a far better option than jail time or significant fines for individuals who have been convicted of any sort of drug or alcohol related crime. For example, a person who has been in prison for driving under the influence of alcohol or drugs may qualify to get treatment services because of their problem as an alternative to serving time in jail. The judge could even order the individual receive rehabilitation, either alone or together with other sentencing. First-time offenders specifically will often be given the chance to choose a criminal justice client rehab instead of other sentencing, and it is well-advised that they take advantage of it when it is an option. The theory behind criminal justice client rehabs is it is far more efficient and effective to invest commitment into rehabilitation 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 that take part in treatment have a better probability of remaining out of the judicial system after rehab.
