Criminal justice client rehabs can be considered as a far better option than jail time or significant fines for many who have already been convicted of any type of drug or alcohol related crime. For example, somebody who has been in prison for driving under the influence of drugs or alcohol may be eligible for treatment services for problem as an alternative to serving time in prison. The judge could even order the individual receive rehab, either alone or in addition to other sentencing. First-time offenders specifically are often given the ability to go with a criminal justice client rehab instead of other sentencing, and it is well-advised they make the most of it if it is a choice. The concept behind criminal justice client rehabs is it is much more efficient and effective to invest effort and time into rehab than enforcement of other consequences. Much research has been done to see how effective this approach is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehabilitation. The signs and indicators seem quite positive, and criminal justice clients that do experience treatment have a much better chance of remaining out of the system after rehab.
