Criminal justice client rehabs can be considered being a considerably better option than prison time or significant fines for many who have already been convicted of any kind of alcohol or drug related crime. By way of example, a person who has been in prison for driving under the influence of alcohol or drugs may be eligible to receive rehabilitation services because of their problem as an alternative to serving time in prison. The judge might even order that the individual receive treatment, either alone or together with other sentencing. First time offenders in particular are often given the opportunity to go with a criminal justice client rehab as an alternative to other sentencing, and it is well-advised that they take advantage of it if it is a possibility. The idea behind criminal justice client rehabs is it is far more effective and efficient to invest effort and time into treatment than enforcement of other consequences. Much research has been carried out to discover how effective this approach is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehab. All indicators seem to be quite positive, and criminal justice clients that experience rehabilitation have a much better chance of remaining out of the judicial system following treatment.
