Criminal justice client rehabs are available as a significantly better option than jail time or heavy fines for those who have already been convicted of any sort of alcohol or drug related crime. For example, anyone who has been in prison for driving drunk of alcohol or drugs may be eligible to obtain rehab services for problem as opposed to serving time in jail. The judge might even order that the individual receive treatment, either alone or along with other consequences. First-time offenders specifically will often be given the ability to choose a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended they reap the benefits of it if it's a choice. The concept behind criminal justice client rehabs is that it is much more effective and efficient to invest effort and time into treatment than enforcement of other consequences. Much research has been done to see how effective this approach is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following treatment. The signs and indicators seem quite positive, and criminal justice clients who do take part in treatment have better probability of remaining out of the judicial system after rehabilitation.
