Criminal justice client rehabs can be considered being a significantly better option than incarceration or significant fines for individuals who have already been convicted of any type of drug or alcohol related crime. For instance, a person who has been found guilty of driving under the influence of drugs or alcohol may qualify to get treatment services for his or her problem instead of serving time in prison. The judge might order the individual receive treatment, either alone or in addition to other sentencing. First time offenders in particular will often be given the opportunity choose a criminal justice client rehab as an alternative to other sentencing, and it is well-advised that they make the most of it when it is an option. The idea behind criminal justice client rehabs is it is much more effective and efficient to invest time and effort into rehabilitation than punishment. Much research has been carried out to discover how effective this strategy is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehab. The signs and indicators appear to be quite positive, and criminal justice clients that experience rehab have better potential for remaining out of the system following rehab.
