Criminal justice client rehabs are available being a far better option than time in jail or significant fines for those who have already been convicted of any sort of drug or alcohol related crime. By way of example, somebody who has been in prison for driving under the influence of drugs or alcohol may be eligible to obtain rehabilitation services because of their problem rather than serving time in jail. The judge might even order the individual receive rehab, either alone or in addition to other sentencing. First time offenders specifically in many cases are given the chance to go with a criminal justice client rehab as opposed to other sentencing, and it is highly recommended that they take advantage of it if it is an alternative. The concept behind criminal justice client rehabs is that it is far more effective and efficient to invest effort and time into treatment than punishment. Much research has been carried out to see how effective this strategy is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehab. All indicators appear to be quite positive, and criminal justice clients that do take part in rehab have a better probability of remaining out of the system following rehab.
