Criminal justice client rehabs can be considered as being a considerably better option than time in jail or significant fines for those who have already been convicted of any sort of alcohol or drug related crime. For example, somebody who has been in prison for driving while impaired of alcohol or drugs may be eligible to obtain rehabilitation services for his or her problem as opposed to serving time in jail. The judge might even order that the individual receive rehabilitation, either alone or together with other consequences. New offenders specifically in many cases are given the ability to select a criminal justice client rehab rather than other sentencing, and it is highly recommended that they take advantage of it if it's an option. The theory behind criminal justice client rehabs is it is way more efficient and effective to invest effort and time into treatment than punishment. Much research has been completed to see how effective this approach is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehab. The signs and indicators appear to be quite positive, and criminal justice clients that do take part in treatment have a much better possibility of remaining out of the judicial system following rehabilitation.
