Criminal justice client rehabs can be considered being a considerably better option than time in jail or heavy fines for those who have already been convicted of any sort of alcohol or drug related crime. As an example, anyone who has been in prison for dui of drugs or alcohol may qualify for rehab services for their problem rather than serving time in prison. The judge may even order the individual receive rehab, either alone or in addition to other sentencing. First-time offenders in particular tend to be given the chance to pick a criminal justice client rehab rather than other sentencing, and it is well-advised they make the most of it when it is a possibility. The idea behind criminal justice client rehabs is it is much more effective and efficient to invest effort and time into rehabilitation than punishment. Much research has been completed 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 treatment. All indicators seem to be quite positive, and criminal justice clients who do take part in rehab have a better chance of remaining out of the judicial system following rehab.
