Criminal justice client rehabs are available like a significantly better option than time in jail or heavy fines for individuals who have already been convicted of any sort of drug or alcohol related crime. For instance, a person who has been found guilty of driving drunk of alcohol or drugs may qualify to receive rehabilitation services because of their problem rather than serving time in jail. The judge could even order that the individual receive treatment, either alone or along with other consequences. First-time offenders in particular are often given the ability to choose a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended they make the most of it when it is a choice. The theory behind criminal justice client rehabs is that it is much more efficient and effective to invest commitment 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 individual returns or not to criminal justice system following rehabilitation. All indicators appear to be quite positive, and criminal justice clients who do take part in rehab have better possibility of remaining out of the judicial system after treatment.
