Criminal justice client rehabs can be considered as being a significantly better option than incarceration or significant fines for many who have already been convicted of any sort of alcohol or drug related crime. For example, somebody who has been in prison for driving drunk of alcohol or drugs may qualify for rehabilitation services for problem as an alternative to serving time in jail. The judge might even order the individual receive rehab, either alone or in addition to other sentencing. First-time offenders in particular will often be given the opportunity to select 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 an alternative. The concept behind criminal justice client rehabs is it is much more efficient and effective to invest time and energy into rehab than enforcement of other consequences. Much research has been carried out to observe how effective this strategy is on recidivism rates, i.e. if the individual returns or not to criminal justice system following treatment. All indicators seem to be quite positive, and criminal justice clients who do experience treatment have better chance of remaining out of the judicial system following treatment.
