Criminal justice client rehabs are available as a far better option than incarceration or significant fines for those who have already been convicted of any kind of drug or alcohol related crime. For example, anyone who has been found guilty of driving drunk of drugs or alcohol may qualify to obtain rehabilitation services for his or her problem as opposed to serving time in jail. The judge may even order that the individual receive treatment, either alone or as well as other sentencing. Very first time offenders specifically tend to be given the chance to choose a criminal justice client rehab rather than other sentencing, and it is highly recommended that they take advantage of it if it is a choice. The theory behind criminal justice client rehabs is that it is far more effective and efficient to invest commitment into rehabilitation than enforcement of other consequences. Much research has been completed to discover 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 seem quite positive, and criminal justice clients that experience rehabilitation have better chance of remaining out of the judicial system after rehabilitation.
