Criminal justice client rehabs can be considered as a considerably better option than jail time or significant fines for individuals who have already been convicted of any sort of drug or alcohol related crime. As an example, a person who has been in prison for dui 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 rehab, either alone or along with other sentencing. First time offenders in particular in many cases are given the chance to select a criminal justice client rehab instead of other sentencing, and it is well-advised that they benefit from it if it's a choice. 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 carried out to see how effective this method is on recidivism rates, i.e. if the individual returns or not to criminal justice system following treatment. The signs and indicators seem quite positive, and criminal justice clients who do experience rehabilitation have a much better probability of remaining out of the judicial system after rehabilitation.
