Criminal justice client rehabs are available being a far better option than prison time or significant fines for many who have been convicted of any sort of drug or alcohol related crime. As an example, a person who has been found guilty of dui of alcohol or drugs may be eligible for rehabilitation services for problem as opposed to serving time in jail. 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 select a criminal justice client rehab instead of other sentencing, and it is highly recommended they benefit from it if it is an option. The theory behind criminal justice client rehabs is that it is far 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 process is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehab. The signs and indicators seem quite positive, and criminal justice clients that experience treatment have a much better probability of remaining out of the system following treatment.
