Criminal justice client rehabs are available as being a far better option than time in jail or significant fines for individuals who have been convicted of any sort of drug or alcohol related crime. As an example, anyone who has been in prison for dui of alcohol or drugs may be eligible for rehabilitation services for his or her problem instead of serving time in jail. The judge may even order the individual receive rehabilitation, either alone or together with other consequences. First time offenders in particular are often given the opportunity to select a criminal justice client rehab as an alternative to other sentencing, and it is well-advised they benefit from it if it is a possibility. The concept behind criminal justice client rehabs is that it is way more efficient and effective to invest time and energy into treatment than enforcement of other consequences. Much research has been done to find out how effective this method is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehab. The signs and indicators seem quite positive, and criminal justice clients that do experience treatment have better potential for remaining out of the system after treatment.
