Criminal justice client rehabs can be considered like a far better option than time in jail or heavy fines for those who have been convicted of any sort of alcohol or drug related crime. For instance, somebody who has been in prison for driving under the influence of alcohol or drugs may qualify to receive treatment services because of their problem instead of serving time in prison. The judge might even order that the individual receive rehabilitation, either alone or along with other consequences. First-time offenders in particular in many cases are given the opportunity choose a criminal justice client rehab as opposed to other sentencing, and it is well-advised that they make the most of it if it is a possibility. The concept behind criminal justice client rehabs is that it is way more effective and efficient to invest effort and time into rehab than enforcement of other consequences. Much research has been done to find out how effective this approach is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehabilitation. The signs and indicators appear to be quite positive, and criminal justice clients who do experience rehab have better probability of remaining out of the judicial system after rehab.
