Criminal justice client rehabs are available as a far better option than time in jail or heavy fines for many who have already been convicted of any sort of drug or alcohol related crime. As an example, a person who has been found guilty of driving drunk of alcohol or drugs may qualify for rehabilitation services for his or her problem instead of serving time in jail. The judge might order that the individual receive rehab, either alone or along with other sentencing. First time offenders in particular will often be given the chance to pick a criminal justice client rehab rather than other sentencing, and it is well-advised they make the most of it if it's a choice. The theory behind criminal justice client rehabs is that it is much more efficient and effective to invest time and effort into rehab than enforcement of other consequences. Much research has been completed to see how effective this process is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehab. All indicators appear to be quite positive, and criminal justice clients who do experience rehab have a better probability of remaining out of the system after treatment.
