Criminal justice client rehabs can be considered being a significantly better option than time in jail or heavy fines for those who have 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 qualify to obtain rehabilitation services for their problem rather than serving time in prison. The judge might even order that the individual receive rehab, either alone or together with other consequences. First-time offenders in particular will often be given the chance to select a criminal justice client rehab as opposed to other sentencing, and it is well-advised they benefit from it if it's a choice. The concept behind criminal justice client rehabs is that it is far more effective and efficient to invest effort and time into rehab than enforcement of other consequences. Much research has been carried out to discover how effective this process is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following treatment. All indicators appear to be quite positive, and criminal justice clients that do experience treatment have better chance of remaining out of the system after treatment.
