Criminal justice client rehabs are available as being a considerably better option than prison time or heavy fines for those who have been convicted of any sort of alcohol or drug related crime. As an example, someone who has been in prison for driving while impaired of drugs or alcohol may be eligible to get rehab services because of their problem as an alternative to serving time in prison. The judge could even order the individual receive rehabilitation, either alone or together with other consequences. Very first time offenders in particular will often be given the ability to pick a criminal justice client rehab instead of other sentencing, and it is well-advised they benefit from it if it is an option. The theory behind criminal justice client rehabs is it is way more effective and efficient to invest effort and time into treatment than enforcement of other consequences. Much research has been done to discover how effective this method is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehab. All indicators seem to be quite positive, and criminal justice clients who do take part in rehab have a much better possibility of remaining out of the system after rehab.
