Criminal justice client rehabs can be considered as a considerably better option than time in jail or heavy fines for many who have been convicted of any sort of drug or alcohol related crime. For example, someone who has been found guilty of driving under the influence of alcohol or drugs may qualify to get rehab services for his or her problem as opposed to serving time in jail. The judge might order that the individual receive treatment, either alone or in addition to other consequences. First time offenders in particular are often given the ability to pick a criminal justice client rehab as an alternative to other sentencing, and it is well-advised they take advantage of it when it is an alternative. The theory behind criminal justice client rehabs is it is far more efficient and effective to invest time and effort into treatment than punishment. 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. The signs and indicators appear to be quite positive, and criminal justice clients who do experience rehab have better potential for remaining out of the system after treatment.
