Criminal justice client rehabs are available as a significantly better option than incarceration or significant fines for many who have already been convicted of any kind of drug or alcohol related crime. For instance, someone who has been found guilty of dui of alcohol or drugs may qualify for treatment services because of their problem as opposed to serving time in prison. The judge may even order that the individual receive treatment, either alone or in addition to other sentencing. Very first time offenders in particular will often be given the ability to go with a criminal justice client rehab rather than other sentencing, and it is highly recommended they make the most of it if it is an option. The idea behind criminal justice client rehabs is that it is far more effective and efficient to invest effort and time into rehabilitation than punishment. Much research has been done to find out how effective this method is on recidivism rates, i.e. if the individual returns or not to criminal justice system following treatment. The signs and indicators appear to be quite positive, and criminal justice clients that experience treatment have a better chance of remaining out of the judicial system after rehab.
