Criminal justice client rehabs can be considered being a considerably better option than time in jail or heavy fines for those who have already been convicted of any kind of drug or alcohol related crime. As an example, someone who has been found guilty of driving drunk of alcohol or drugs may qualify for rehab services for problem instead of serving time in prison. The judge might even order the individual receive treatment, either alone or in addition to other sentencing. First-time offenders in particular will often be given the opportunity to select a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended they make the most of it when it is an option. The concept behind criminal justice client rehabs is it is much more effective and efficient to invest time and energy into treatment than punishment. Much research has been carried out 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 rehab. The signs and indicators appear to be quite positive, and criminal justice clients who take part in treatment have better possibility of remaining out of the judicial system after rehabilitation.
