Criminal justice client rehabs are available as a significantly better option than incarceration or heavy fines for many who have already been convicted of any kind of alcohol or drug related crime. For instance, a person who has been in prison for driving under the influence of alcohol or drugs may be eligible to obtain rehab services because of their problem as an alternative to serving time in jail. The judge might even order the individual receive treatment, either alone or in addition to other consequences. First time offenders specifically in many cases are given the chance to go with a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended that they benefit from it if it is a choice. The idea behind criminal justice client rehabs is it is much more efficient and effective to invest time and energy into rehab than punishment. Much research has been completed to observe how effective this approach is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehab. All indicators seem to be quite positive, and criminal justice clients who take part in rehab have a better potential for remaining out of the judicial system following rehab.
