Criminal justice client rehabs are available like a considerably better option than time in jail or heavy fines for those who have already been convicted of any sort of drug or alcohol related crime. For example, someone who has been in prison for driving drunk of alcohol or drugs may be eligible to get rehab services because of their problem as opposed to serving time in prison. The judge might even order the individual receive treatment, either alone or in addition to other consequences. New offenders in particular are often given the chance to choose a criminal justice client rehab rather than other sentencing, and it is well-advised that they make the most of it when it is an alternative. The concept behind criminal justice client rehabs is that it is much more effective and efficient to invest time and effort into rehab than enforcement of other consequences. Much research has been done to observe how effective this method is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehabilitation. The signs and indicators seem quite positive, and criminal justice clients who take part in rehabilitation have better probability of remaining out of the judicial system following rehab.
