Criminal justice client rehabs are available like a far better option than time in jail or significant fines for those who have been convicted of any type of drug or alcohol related crime. For example, someone who has been found guilty of driving under the influence of drugs or alcohol may be eligible to receive treatment services for their problem as opposed to serving time in jail. The judge might order that the individual receive rehab, either alone or together with other sentencing. Very first time 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 well-advised they take advantage of it when it is an alternative. The concept behind criminal justice client rehabs is it is way more efficient and effective to invest time and effort into treatment than enforcement of other consequences. Much research has been done to see how effective this approach is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehab. The signs and indicators seem quite positive, and criminal justice clients who do experience treatment have a better possibility of remaining out of the judicial system following rehabilitation.
