Criminal justice client rehabs are available being a far better option than jail time or significant fines for those who have been convicted of any type of drug or alcohol related crime. By way of example, anyone who has been in prison for driving under the influence of drugs or alcohol may be eligible to get treatment services for his or her problem instead of serving time in jail. The judge might even order that the individual receive rehab, either alone or in addition to other sentencing. First time offenders specifically in many cases are given the chance to go with a criminal justice client rehab as opposed to other sentencing, and it is well-advised that they take advantage of it when it is an option. The concept behind criminal justice client rehabs is that it is way more effective and efficient to invest effort and time into treatment than enforcement of other consequences. Much research has been carried out to see how effective this strategy is on recidivism rates, i.e. if the individual returns or not to criminal justice system following treatment. All indicators appear to be quite positive, and criminal justice clients that experience rehabilitation have a much better potential for remaining out of the judicial system after rehab.
