Criminal justice client rehabs are available as being a far better option than jail time or significant fines for those who have already been convicted of any sort of drug or alcohol related crime. As an example, anyone who has been in prison for driving while impaired of drugs or alcohol may be eligible to receive rehabilitation services for their problem as opposed to serving time in prison. The judge might order that the individual receive rehab, either alone or together with other consequences. First-time offenders specifically in many cases are given the chance to select a criminal justice client rehab as an alternative to other sentencing, and it is well-advised they make the most of it if it is a choice. The idea behind criminal justice client rehabs is that it is much more efficient and effective to invest time and energy into rehabilitation than punishment. Much research has been completed to see how effective this process is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following treatment. All indicators seem to be quite positive, and criminal justice clients who take part in rehab have a better potential for remaining out of the system after rehabilitation.
