Criminal justice client rehabs are available as being a considerably better option than incarceration or heavy fines for individuals 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 their problem as an alternative to serving time in jail. The judge might even order the individual receive treatment, either alone or along with other consequences. First-time offenders specifically are often given the ability to select a criminal justice client rehab as opposed to other sentencing, and it is highly recommended they benefit from it when it is an option. 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 discover how effective this approach is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehab. The signs and indicators seem to be quite positive, and criminal justice clients who experience rehab have better probability of remaining out of the system following rehabilitation.
