Criminal justice client rehabs are available as being a considerably better option than incarceration or heavy fines for those who have already been convicted of any sort of alcohol or drug related crime. For example, anyone who has been in prison for driving while impaired of drugs or alcohol may be eligible for rehab services for their problem as opposed to serving time in jail. The judge may even order that the individual receive rehab, either alone or as well as other consequences. Very first time offenders in particular tend to be given the opportunity to pick a criminal justice client rehab instead of other sentencing, and it is well-advised they take advantage of it if it is an option. The theory behind criminal justice client rehabs is that it is way more efficient and effective to invest commitment into rehabilitation than punishment. Much research has been completed to see how effective this method is on recidivism rates, i.e. if the individual returns or not to criminal justice system following treatment. All indicators seem quite positive, and criminal justice clients who experience rehab have a better potential for remaining out of the system after rehabilitation.
