Criminal justice client rehabs can be considered as a far better option than time in jail or heavy fines for many who have already been convicted of any kind of alcohol or drug related crime. As an example, a person who has been found guilty of driving under the influence of drugs or alcohol may be eligible for rehab services because of their problem rather than 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 opportunity to go with a criminal justice client rehab as opposed to other sentencing, and it is highly recommended that they take advantage of it if 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 rehab than punishment. Much research has been carried out to discover how effective this method is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehab. The signs and indicators appear to be quite positive, and criminal justice clients that experience rehabilitation have a better chance of remaining out of the judicial system after treatment.
