Criminal justice client rehabs are available as a considerably better option than incarceration or significant fines for individuals who have been convicted of any kind of alcohol or drug related crime. For instance, somebody who has been in prison for driving while impaired of drugs or alcohol may be eligible to receive treatment services for their problem instead of serving time in jail. The judge could even order that the individual receive rehab, either alone or as well as other sentencing. First-time offenders specifically tend to be given the opportunity to select a criminal justice client rehab instead of 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 much more efficient and effective to invest time and energy into rehabilitation than punishment. Much research has been completed to find out how effective this process is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehabilitation. The signs and indicators seem quite positive, and criminal justice clients that do take part in treatment have a better chance of remaining out of the judicial system after treatment.
