Criminal justice client rehabs are available as being a considerably better option than time in jail or significant fines for those who have already been convicted of any kind of alcohol or drug related crime. As an example, a person who has been in prison for driving under the influence of alcohol or drugs may qualify to obtain rehabilitation services because of their problem instead of serving time in prison. The judge might even order the individual receive treatment, either alone or along with other sentencing. First time offenders specifically in many cases are given the opportunity go with a criminal justice client rehab as opposed to other sentencing, and it is highly recommended they reap the benefits of it when it is a choice. The idea behind criminal justice client rehabs is that it is much more effective and efficient to invest effort and time into rehab 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 treatment. All indicators seem quite positive, and criminal justice clients that take part in rehab have better possibility of remaining out of the judicial system after rehabilitation.
