Criminal justice client rehabs are available like a significantly better option than incarceration or heavy fines for many who have already been convicted of any kind 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 for treatment services because of their problem as opposed to serving time in jail. The judge may even order the individual receive rehab, either alone or in addition to other sentencing. First time offenders specifically in many cases are given the chance to select a criminal justice client rehab rather than other sentencing, and it is highly recommended that they make the most of it if it's a choice. The theory behind criminal justice client rehabs is it is far more effective and efficient to invest time and effort into rehabilitation than enforcement of other consequences. Much research has been carried out to see 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 do experience rehabilitation have better possibility of remaining out of the judicial system after rehab.
