Criminal justice client rehabs can be considered as a considerably better option than jail time or significant fines for those who have already been convicted of any type of drug or alcohol related crime. As an example, a person who has been in prison for dui of alcohol or drugs may qualify to get treatment services because of their problem as an alternative to serving time in jail. The judge may even order the individual receive treatment, either alone or together with other sentencing. First time offenders specifically will often be given the opportunity to pick a criminal justice client rehab as an alternative to other sentencing, and it is well-advised that they reap the benefits of it when it is a choice. The theory behind criminal justice client rehabs is it is way more efficient and effective to invest commitment into rehabilitation than punishment. Much research has been carried out to observe how effective this approach 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 do take part in rehabilitation have a better possibility of remaining out of the system after rehabilitation.
