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 type of alcohol or drug related crime. For example, someone who has been found guilty of dui of drugs or alcohol may qualify to get rehabilitation services for their problem rather than serving time in jail. The judge might even order the individual receive treatment, either alone or together with other consequences. First-time offenders in particular in many cases are given the ability to go with a criminal justice client rehab as opposed to other sentencing, and it is well-advised that they take advantage of it if it is a possibility. The theory behind criminal justice client rehabs is it is much more efficient and effective to invest commitment into rehabilitation than enforcement of other consequences. Much research has been carried out to observe how effective this process is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehab. All indicators appear to be quite positive, and criminal justice clients that do experience rehabilitation have better chance of remaining out of the system after rehabilitation.
