Criminal justice client rehabs are available as being a considerably better option than jail time or heavy fines for those who have already been convicted of any type of drug or alcohol related crime. As an example, anyone who has been in prison for dui of alcohol or drugs may be eligible for rehab services for their problem as an alternative to serving time in prison. The judge might order that the individual receive rehab, either alone or in addition to other consequences. Very first time offenders in particular will often be given the chance to pick a criminal justice client rehab rather than other sentencing, and it is well-advised that they take advantage of it if it is an option. The idea behind criminal justice client rehabs is it is far more efficient and effective to invest time and effort into rehabilitation than enforcement of other consequences. Much research has been completed 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 treatment. The signs and indicators appear to be quite positive, and criminal justice clients that do experience treatment have better probability of remaining out of the judicial system following rehabilitation.
