Criminal justice client rehabs can be considered as being a considerably better option than incarceration or heavy fines for many who have already been convicted of any kind of alcohol or drug related crime. By way of example, a person who has been in prison for driving under the influence of drugs or alcohol may qualify for treatment services because of their problem as opposed to serving time in jail. The judge may even order that the individual receive rehab, either alone or along with other sentencing. New offenders in particular in many cases are given the ability to choose a criminal justice client rehab instead of other sentencing, and it is highly recommended that they make the most of it if it is a possibility. The theory behind criminal justice client rehabs is that it is far more efficient and effective to invest time and energy into rehab than punishment. Much research has been carried out to see how effective this process is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehabilitation. All indicators seem to be quite positive, and criminal justice clients that take part in rehabilitation have a much better potential for remaining out of the system after rehab.
