Criminal justice client rehabs are available as a far better option than jail time or heavy fines for many who have already been convicted of any kind of alcohol or drug related crime. As an example, someone who has been in prison for driving under the influence of drugs or alcohol may be eligible for rehabilitation services because of their problem as an alternative to serving time in jail. The judge might even order that the individual receive treatment, either alone or together with other consequences. New offenders in particular in many cases are given the ability to choose a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended they reap the benefits of it if it is a choice. The concept behind criminal justice client rehabs is that it is much more efficient and effective to invest time and energy into rehab than punishment. Much research has been carried out to see how effective this process is on recidivism rates, i.e. if the individual returns or not to criminal justice system following treatment. The signs and indicators appear to be quite positive, and criminal justice clients who do experience rehab have a better possibility of remaining out of the system after rehab.
