Criminal justice client rehabs can be considered as being a considerably better option than incarceration or heavy fines for individuals who have already been convicted of any sort of drug or alcohol related crime. By way of example, someone who has been in prison for driving under the influence of alcohol or drugs may be eligible to receive rehab services because of their problem instead of serving time in jail. The judge may even order that the individual receive rehab, either alone or along with other consequences. Very first time offenders specifically in many cases are given the ability to choose a criminal justice client rehab rather than other sentencing, and it is well-advised that they make the most of it when it is an option. The theory behind criminal justice client rehabs is that it is way more efficient and effective to invest effort and time into rehabilitation than punishment. Much research has been done to observe how effective this approach is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehabilitation. All indicators appear to be quite positive, and criminal justice clients that experience treatment have a better probability of remaining out of the system following treatment.
