Criminal justice client rehabs are available as a considerably better option than prison time or heavy fines for those who have already been convicted of any kind of drug or alcohol related crime. For example, someone who has been in prison for driving while impaired of drugs or alcohol may qualify to get rehabilitation services for problem as opposed to serving time in jail. The judge could even order the individual receive rehabilitation, 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 rather than other sentencing, and it is highly recommended they make the most of it if it is an option. The concept behind criminal justice client rehabs is it is much more efficient and effective to invest commitment into rehab than enforcement of other consequences. Much research has been completed to observe 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 quite positive, and criminal justice clients who do experience rehabilitation have a much better chance of remaining out of the system after rehab.
