Criminal justice client rehabs can be considered as being a significantly better option than prison time or significant fines for those who have already been convicted of any sort of drug or alcohol related crime. For instance, someone who has been found guilty of dui of alcohol or drugs may be eligible to obtain rehabilitation services for their problem as opposed to serving time in jail. The judge might even order that the individual receive rehab, either alone or in addition to other sentencing. New offenders specifically in many cases are given the ability to choose a criminal justice client rehab as opposed to other sentencing, and it is highly recommended they make the most of it when it is a possibility. The idea behind criminal justice client rehabs is it is much more efficient and effective to invest effort and time into treatment than punishment. Much research has been completed to find out how effective this method is on recidivism rates, i.e. if the criminal justice client 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 treatment have better possibility of remaining out of the system following rehabilitation.
