Criminal justice client rehabs can be considered as a considerably better option than jail time or heavy fines for individuals who have already been convicted of any sort of drug or alcohol related crime. As an example, anyone who has been in prison for driving under the influence of alcohol or drugs may be eligible to obtain rehabilitation services for his or her problem as opposed to serving time in prison. The judge could even order that the individual receive rehab, either alone or as well as other sentencing. Very first time offenders in particular will often be given the opportunity to go with a criminal justice client rehab instead of other sentencing, and it is highly recommended that they benefit from it if it is a possibility. The theory behind criminal justice client rehabs is it is much more efficient and effective to invest commitment into treatment than enforcement of other consequences. Much research has been completed to observe how effective this strategy 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 take part in rehabilitation have a much better possibility of remaining out of the judicial system following rehab.
