Criminal justice client rehabs can be considered like a far better option than jail time or heavy fines for those who have already been convicted of any type of drug or alcohol related crime. By way of example, somebody who has been found guilty of driving under the influence of drugs or alcohol may qualify to receive rehabilitation services for problem as opposed to serving time in jail. The judge may even order that the individual receive rehabilitation, either alone or in addition to other sentencing. First time offenders in particular tend to be given the opportunity to pick a criminal justice client rehab as opposed to other sentencing, and it is highly recommended they make the most of it when it is an option. The theory behind criminal justice client rehabs is that it is way more effective and efficient to invest time and energy into rehabilitation than enforcement of other consequences. Much research has been done 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. The signs and indicators seem quite positive, and criminal justice clients that do experience treatment have a better possibility of remaining out of the system following treatment.
