Criminal justice client rehabs are available being a considerably better option than time in jail or heavy fines for those who have been convicted of any sort of alcohol or drug related crime. By way of example, anyone who has been found guilty of driving while impaired of drugs or alcohol may be eligible to receive treatment services for problem rather than serving time in jail. The judge might order the individual receive rehab, either alone or in addition to other consequences. First time offenders specifically are often given the opportunity go with a criminal justice client rehab rather than other sentencing, and it is well-advised they take advantage of it when it is a choice. The theory behind criminal justice client rehabs is it is much more efficient and effective to invest effort and time into rehab than enforcement of other consequences. Much research has been completed to observe how effective this strategy is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehab. All indicators appear to be quite positive, and criminal justice clients who do take part in treatment have a much better chance of remaining out of the system following rehab.
