Criminal justice client rehabs can be considered as being a far better option than jail time or significant fines for those who have already been convicted of any type of alcohol or drug related crime. For example, someone who has been in prison for driving while impaired of alcohol or drugs may be eligible to obtain treatment services for their problem as opposed to serving time in prison. The judge might even order that the individual receive rehabilitation, either alone or in addition to other sentencing. New offenders in particular tend to be given the opportunity to pick a criminal justice client rehab instead of other sentencing, and it is highly recommended they reap the benefits of it if it's 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 done to observe how effective this approach is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehabilitation. All indicators seem to be quite positive, and criminal justice clients who do experience treatment have a better chance of remaining out of the system after rehab.
