Criminal justice client rehabs are available being a significantly better option than prison time or heavy fines for those who have already been convicted of any sort of drug or alcohol related crime. For instance, someone who has been in prison for driving while impaired of drugs or alcohol may be eligible to receive treatment services for problem as opposed to serving time in prison. The judge could even order that the individual receive treatment, either alone or in addition to other consequences. First-time offenders in particular will often be given the ability to go with a criminal justice client rehab as an alternative to other sentencing, and it is well-advised that they make the most of it when it is an option. The concept behind criminal justice client rehabs is it is far more effective and efficient to invest time and energy into rehab than punishment. Much research has been carried out to observe how effective this approach is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehab. The signs and indicators seem to be quite positive, and criminal justice clients that experience treatment have a better potential for remaining out of the judicial system following rehab.
