Criminal justice client rehabs are available as a significantly better option than time in jail or heavy fines for individuals who have already been convicted of any type of drug or alcohol related crime. As an example, somebody who has been in prison for dui of alcohol or drugs may qualify for rehab services because of their problem as an alternative to serving time in jail. The judge may even order the individual receive rehabilitation, either alone or along with other consequences. First-time offenders specifically will often be given the ability to pick a criminal justice client rehab as opposed to other sentencing, and it is highly recommended that they benefit from it when it is an alternative. The idea behind criminal justice client rehabs is it is far more effective and efficient to invest time and effort into rehabilitation than enforcement of other consequences. Much research has been carried out to discover how effective this process is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehab. All indicators seem quite positive, and criminal justice clients who take part in rehab have better potential for remaining out of the system after treatment.
