Criminal justice client rehabs can be considered as being a significantly better option than prison time or significant fines for individuals who have been convicted of any sort of alcohol or drug related crime. By way of example, somebody who has been in prison for driving under the influence of alcohol or drugs may be eligible to obtain rehabilitation services for his or her problem instead of serving time in prison. The judge might even order the individual receive rehab, either alone or in addition to other sentencing. Very first time offenders in particular in many cases are given the chance to select a criminal justice client rehab as opposed to other sentencing, and it is highly recommended that they benefit from it if it is a possibility. The idea behind criminal justice client rehabs is it is much more effective and efficient to invest effort and time into treatment than enforcement of other consequences. Much research has been carried out to see 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 appear to be quite positive, and criminal justice clients that do take part in rehabilitation have a much better possibility of remaining out of the system after rehabilitation.
