Criminal justice client rehabs can be considered being a far better option than time in jail or heavy fines for many who have already been convicted of any sort of alcohol or drug related crime. For instance, somebody who has been in prison for driving drunk of alcohol or drugs may be eligible for treatment services for problem rather than serving time in jail. The judge might order that the individual receive rehabilitation, either alone or together with other sentencing. First time offenders in particular will often be given the chance to select a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended they take advantage of it when it is an option. The theory behind criminal justice client rehabs is it is far more efficient and effective to invest time and effort into treatment than enforcement of other consequences. Much research has been completed to observe how effective this process is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehabilitation. All indicators seem quite positive, and criminal justice clients who do experience rehab have a much better chance of remaining out of the system after rehab.
