Criminal justice client rehabs can be considered as a far better option than prison time or significant fines for those who have already been convicted of any sort of alcohol or drug related crime. By way of example, anyone who has been in prison for dui of alcohol or drugs may be eligible to get treatment services because of their problem instead of serving time in jail. The judge might even order that the individual receive treatment, either alone or in addition to other sentencing. Very first time offenders in particular tend to be given the opportunity to select a criminal justice client rehab instead of other sentencing, and it is well-advised they reap the benefits of it if it is an option. The theory behind criminal justice client rehabs is that it is way more efficient and effective to invest effort and time into treatment than punishment. 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 that do experience rehab have a much better probability of remaining out of the judicial system following rehab.
