Criminal justice client rehabs can be considered as being a considerably better option than prison time or significant fines for those who have already been convicted of any type of alcohol or drug related crime. By way of example, someone who has been found guilty of driving while impaired of alcohol or drugs may qualify to obtain rehabilitation services because of their problem rather than serving time in jail. The judge could even order that the individual receive rehab, either alone or together with other sentencing. First time offenders in particular will often be given the ability to pick a criminal justice client rehab as an alternative to other sentencing, and it is well-advised that they take advantage of it when it is a choice. The concept behind criminal justice client rehabs is that it is way more effective and efficient to invest effort and time into treatment than enforcement of other consequences. Much research has been completed to find out how effective this process is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehabilitation. All indicators seem to be quite positive, and criminal justice clients that do take part in treatment have better possibility of remaining out of the judicial system after rehabilitation.
