Criminal justice client rehabs are available as a far better option than prison time or significant fines for those who have already been convicted of any type of drug or alcohol related crime. As an example, anyone who has been in prison for dui of drugs or alcohol may be eligible for treatment services because of their problem as an alternative to serving time in jail. The judge might order that the individual receive treatment, either alone or together with other consequences. First time offenders specifically are often given the opportunity to pick a criminal justice client rehab rather than other sentencing, and it is highly recommended they take advantage of it if it is a choice. The concept behind criminal justice client rehabs is it is way more efficient and effective to invest time and energy into rehabilitation than enforcement of other consequences. 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 treatment. The signs and indicators seem quite positive, and criminal justice clients who experience treatment have better possibility of remaining out of the system after rehabilitation.
