Criminal justice client rehabs are available as being a far better option than jail time or heavy fines for those who have already been convicted of any sort of drug or alcohol related crime. As an example, anyone who has been found guilty of driving while impaired of alcohol or drugs may be eligible to get rehabilitation services because of their problem rather than serving time in jail. The judge may even order the individual receive treatment, either alone or in addition to other sentencing. New offenders specifically tend to be given the chance to pick a criminal justice client rehab instead of other sentencing, and it is highly recommended they reap the benefits of it if it's a choice. The theory behind criminal justice client rehabs is it is far more effective and efficient to invest effort and time into rehab than enforcement of other consequences. Much research has been completed to observe how effective this process 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 take part in rehab have better probability of remaining out of the judicial system following rehab.
