Criminal justice client rehabs can be considered as a considerably better option than time in jail or significant fines for those who have already been convicted of any sort of alcohol or drug related crime. For example, someone who has been found guilty of driving while impaired of alcohol or drugs may qualify to obtain rehabilitation services for their problem as opposed to serving time in prison. The judge may even order the individual receive rehab, either alone or as well as other consequences. First time offenders specifically are often given the chance to go with a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended that they take advantage of it if it is a possibility. The theory behind criminal justice client rehabs is it is way more efficient and effective to invest commitment into rehabilitation than enforcement of other consequences. Much research has been carried out to discover how effective this approach is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehab. All indicators seem to be quite positive, and criminal justice clients who take part in rehabilitation have a better probability of remaining out of the system after treatment.
