Criminal justice client rehabs are available like a far better option than time in jail or significant fines for many who have been convicted of any type of alcohol or drug related crime. For example, someone who has been in prison for 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 the individual receive treatment, either alone or along with other sentencing. First time offenders specifically in many cases are given the chance to select a criminal justice client rehab as opposed to other sentencing, and it is well-advised they benefit from it when it is a choice. The theory behind criminal justice client rehabs is it is far more efficient and effective to invest effort and time into treatment than enforcement of other consequences. Much research has been done to see how effective this strategy is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehabilitation. All indicators seem to be quite positive, and criminal justice clients who do take part in treatment have better probability of remaining out of the system after rehab.
