Criminal justice client rehabs can be considered as being a far better option than time in jail or significant 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 alcohol or drugs may be eligible to get treatment services for their problem rather than serving time in jail. The judge might order that the individual receive rehabilitation, either alone or as well as other sentencing. First time offenders in particular are often given the opportunity pick a criminal justice client rehab instead of other sentencing, and it is highly recommended that they make the most of it when it is an alternative. The concept behind criminal justice client rehabs is it is much more effective and efficient to invest time and energy into treatment than enforcement of other consequences. Much research has been done to see how effective this method is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehab. The signs and indicators seem quite positive, and criminal justice clients who experience treatment have a better possibility of remaining out of the system after rehab.
