Criminal justice client rehabs are available as a far 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 instance, somebody who has been found guilty of driving under the influence of drugs or alcohol may qualify to receive rehab services for his or her problem instead of serving time in jail. The judge might order the individual receive rehabilitation, either alone or as well as other sentencing. First time offenders specifically tend to be given the chance to select a criminal justice client rehab rather than other sentencing, and it is highly recommended that they benefit from it when it is an option. The concept behind criminal justice client rehabs is that it is far more effective and efficient to invest effort and time into rehabilitation 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 treatment. The signs and indicators seem quite positive, and criminal justice clients that do take part in rehab have a much better probability of remaining out of the system after treatment.
