Criminal justice client rehabs are available like a considerably better option than time in jail or heavy fines for individuals who have already been convicted of any sort of alcohol or drug related crime. By way of example, anyone who has been in prison for driving under the influence of alcohol or drugs may qualify for rehab services for their problem as an alternative to serving time in jail. The judge might order the individual receive rehab, either alone or together with other consequences. First-time offenders specifically in many cases are given the chance to go with a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended they benefit from it if it is a possibility. The idea behind criminal justice client rehabs is that it is much more efficient and effective to invest time and energy into rehab than enforcement of other consequences. Much research has been done to observe how effective this method is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehab. The signs and indicators seem to be quite positive, and criminal justice clients who do take part in rehabilitation have a better possibility of remaining out of the system after rehabilitation.
