Criminal justice client rehabs are available being a significantly better option than incarceration or significant fines for those who have already been convicted of any kind of alcohol or drug related crime. For instance, someone who has been found guilty of driving under the influence of drugs or alcohol may qualify to receive treatment services for their problem as an alternative to serving time in prison. The judge may even order that the individual receive treatment, either alone or as well as other sentencing. First time offenders in particular tend to be given the opportunity choose a criminal justice client rehab as opposed to other sentencing, and it is well-advised they benefit from it if it is an alternative. The idea behind criminal justice client rehabs is it is way more effective and efficient to invest time and energy into rehab than enforcement of other consequences. Much research has been done to observe how effective this method is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following treatment. All indicators appear to be quite positive, and criminal justice clients who do take part in rehab have a much better potential for remaining out of the system after treatment.
