Criminal justice client rehabs are available as being a significantly better option than time in jail or significant fines for those who have been convicted of any type of alcohol or drug related crime. For example, someone who has been found guilty of driving under the influence of alcohol or drugs may qualify to obtain rehabilitation services because of their problem as an alternative to serving time in jail. The judge may even order that the individual receive rehab, either alone or in addition to other consequences. First-time offenders in particular will often be given the opportunity select a criminal justice client rehab instead of other sentencing, and it is well-advised they take advantage of it when it is a possibility. The theory behind criminal justice client rehabs is that it is much more efficient and effective to invest commitment into rehabilitation 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 rehabilitation. All indicators seem quite positive, and criminal justice clients that experience rehabilitation have a better chance of remaining out of the system after rehabilitation.
