Criminal justice client rehabs can be considered like a significantly better option than jail time or heavy fines for those who have already been convicted of any sort of drug or alcohol related crime. As an example, someone who has been in prison for dui of drugs or alcohol may qualify to get rehab services because of their problem as an alternative to serving time in prison. The judge may even order that the individual receive treatment, either alone or together with other consequences. First-time offenders specifically will often be given the opportunity pick a criminal justice client rehab rather than other sentencing, and it is well-advised that they make the most of it if it's a choice. The theory behind criminal justice client rehabs is it is much more effective and efficient to invest effort and time into treatment than enforcement of other consequences. Much research has been carried out to observe how effective this method is on recidivism rates, i.e. if the individual returns or not to criminal justice system following treatment. All indicators seem to be quite positive, and criminal justice clients who do take part in rehab have better probability of remaining out of the system after rehab.
