Criminal justice client rehabs can be considered being a far better option than incarceration or heavy fines for individuals who have already been convicted of any kind of drug or alcohol related crime. For example, somebody who has been in prison for driving under the influence of alcohol or drugs may be eligible for treatment services for his or her problem rather than serving time in jail. The judge may even order that the individual receive treatment, either alone or in addition to other consequences. Very first time offenders specifically in many cases are given the opportunity go with a criminal justice client rehab rather than other sentencing, and it is highly recommended they make the most of it if it's an option. The concept behind criminal justice client rehabs is that it is far more efficient and effective to invest time and energy into rehabilitation than punishment. Much research has been carried out to find out 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 seem to be quite positive, and criminal justice clients that do take part in rehab have a better probability of remaining out of the system after rehabilitation.
