Criminal justice client rehabs can be considered as being a far better option than prison time or significant fines for individuals who have already been convicted of any sort of alcohol or drug related crime. For instance, someone who has been in prison for dui of alcohol or drugs may be eligible to obtain treatment services for his or her problem instead of serving time in prison. The judge could even order that the individual receive treatment, either alone or together with other consequences. First-time offenders in particular are often given the chance to select 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 option. The concept behind criminal justice client rehabs is that it is much more efficient and effective to invest effort and time into treatment than enforcement of other consequences. Much research has been carried out to discover how effective this strategy is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehabilitation. All indicators appear to be quite positive, and criminal justice clients who experience rehab have a better possibility of remaining out of the system after treatment.
