Criminal justice client rehabs can be considered like a far better option than time in jail or heavy fines for those who have already been convicted of any kind of alcohol or drug related crime. For example, anyone who has been found guilty of dui of alcohol or drugs may be eligible for treatment services because of their problem rather than serving time in jail. The judge might order the individual receive rehabilitation, either alone or in addition to other sentencing. First-time offenders specifically in many cases are given the chance to choose a criminal justice client rehab instead of other sentencing, and it is highly recommended they take advantage of it if it is an option. The idea behind criminal justice client rehabs is it is way more effective and efficient to invest effort and time into rehab than enforcement of other consequences. Much research has been carried out to observe how effective this process is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehab. All indicators seem to be quite positive, and criminal justice clients that experience rehabilitation have better possibility of remaining out of the system following rehab.
