Criminal justice client rehabs are available as a considerably better option than time in jail or significant fines for those who have been convicted of any sort of alcohol or drug related crime. By way of example, anyone who has been in prison for dui of alcohol or drugs may qualify to receive rehabilitation services because of their problem as an alternative to serving time in prison. The judge could even order the individual receive rehab, either alone or together with other sentencing. First time offenders specifically tend to be given the opportunity to go with a criminal justice client rehab rather than other sentencing, and it is highly recommended that they take advantage of it when it is an alternative. The theory behind criminal justice client rehabs is that it is much more effective and efficient to invest time and effort into treatment than enforcement of other consequences. Much research has been completed to discover how effective this method is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehab. All indicators appear to be quite positive, and criminal justice clients that do take part in rehab have better possibility of remaining out of the system after rehabilitation.
