Criminal justice client rehabs are available as a far better option than prison time or heavy fines for many who have been convicted of any type of alcohol or drug related crime. For example, anyone who has been found guilty of driving under the influence of alcohol or drugs may be eligible for rehab services for his or her problem rather than serving time in jail. The judge might order that the individual receive rehabilitation, either alone or together with other sentencing. First time offenders specifically in many cases are given the chance to select a criminal justice client rehab rather than other sentencing, and it is well-advised they benefit from it if it is an alternative. The theory behind criminal justice client rehabs is it is way more efficient and effective to invest commitment into treatment than enforcement of other consequences. Much research has been completed to find out how effective this method 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 that take part in treatment have a better probability of remaining out of the system following rehab.
