Criminal justice client rehabs can be considered like a considerably better option than jail time or heavy fines for those who have been convicted of any type of alcohol or drug related crime. As an example, anyone who has been found guilty of driving under the influence of alcohol or drugs may be eligible for treatment services for problem as opposed to serving time in prison. The judge might even order that the individual receive rehab, either alone or along with other sentencing. First-time offenders specifically in many cases are given the opportunity to pick a criminal justice client rehab rather than other sentencing, and it is well-advised that they make the most of it if it is a choice. The theory behind criminal justice client rehabs is that it is much more effective and efficient to invest time and effort into treatment than enforcement of other consequences. Much research has been done to see how effective this method is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehabilitation. All indicators seem quite positive, and criminal justice clients who do experience rehab have a better potential for remaining out of the system following rehab.
