Criminal justice client rehabs can be considered as being a significantly better option than time in jail or significant fines for individuals who have been convicted of any sort of drug or alcohol related crime. By way of example, a person who has been in prison for driving under the influence of alcohol or drugs may be eligible to receive rehabilitation services because of their problem as an alternative to serving time in jail. The judge could even order that the individual receive rehabilitation, either alone or in addition to other sentencing. First time offenders in particular in many cases are given the opportunity pick a criminal justice client rehab instead of other sentencing, and it is highly recommended that they reap the benefits of it if it is an alternative. The theory behind criminal justice client rehabs is that it is far more effective and efficient to invest time and effort into rehab than enforcement of other consequences. Much research has been completed to see how effective this method is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehab. The signs and indicators seem to be quite positive, and criminal justice clients that experience treatment have a better possibility of remaining out of the system following rehab.
