Criminal justice client rehabs are available as a considerably better option than jail time or heavy fines for many who have been convicted of any kind of drug or alcohol related crime. For instance, a person who has been found guilty of driving under the influence of alcohol or drugs may be eligible to obtain rehabilitation services because of their problem as opposed to serving time in prison. The judge might even order that the individual receive treatment, either alone or together with other consequences. First time offenders in particular will often be given the chance to choose a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended they make the most of it if it is an alternative. The concept behind criminal justice client rehabs is it is way more effective and efficient to invest effort and time into treatment than enforcement of other consequences. Much research has been done to discover how effective this approach is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following treatment. All indicators appear to be quite positive, and criminal justice clients who experience rehab have better possibility of remaining out of the system following treatment.
