Criminal justice client rehabs are available as being a significantly better option than incarceration or significant fines for individuals who have been convicted of any kind of alcohol or drug related crime. As an example, someone who has been in prison for dui of drugs or alcohol may qualify to receive treatment services for problem instead of serving time in jail. The judge could even order that the individual receive treatment, either alone or together with other sentencing. First-time offenders specifically in many cases are given the opportunity to select a criminal justice client rehab rather than other sentencing, and it is well-advised they take advantage of it when it is a choice. The idea behind criminal justice client rehabs is that it is far more effective and efficient to invest effort and time into rehab than punishment. Much research has been carried out 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 that take part in rehab have a better probability of remaining out of the system after rehabilitation.
