Criminal justice client rehabs are available being a considerably better option than jail time or heavy fines for many who have already been convicted of any type of drug or alcohol related crime. For example, somebody who has been found guilty of driving under the influence of alcohol or drugs may qualify for treatment services because of their problem rather than serving time in prison. The judge might order that the individual receive rehabilitation, either alone or in addition to other sentencing. First-time offenders in particular are often given the chance to choose a criminal justice client rehab as opposed to other sentencing, and it is highly recommended they take advantage of it when it is a choice. The idea behind criminal justice client rehabs is that it is way more effective and efficient to invest time and energy into rehab than enforcement of other consequences. Much research has been done to observe how effective this process is on recidivism rates, i.e. if the individual returns or not to criminal justice system following treatment. All indicators appear to be quite positive, and criminal justice clients who do experience rehabilitation have better potential for remaining out of the judicial system following treatment.
