Criminal justice client rehabs are available like a considerably better option than prison time or significant fines for many who have already been convicted of any sort of drug or alcohol related crime. For instance, somebody who has been in prison for driving under the influence of drugs or alcohol may qualify to receive rehabilitation services for his or her problem instead of serving time in prison. The judge could even order that the individual receive treatment, either alone or together with other sentencing. New offenders in particular will often be given the opportunity pick a criminal justice client rehab as opposed to other sentencing, and it is well-advised they reap the benefits of it if it is a possibility. The theory behind criminal justice client rehabs is it is much more effective and efficient to invest time and effort into rehab than punishment. Much research has been completed to observe 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 to be quite positive, and criminal justice clients who experience rehabilitation have better probability of remaining out of the system after rehabilitation.
