Criminal justice client rehabs are available as being a considerably better option than jail time or significant fines for those who have already been convicted of any kind of drug or alcohol related crime. For instance, someone who has been found guilty of driving under the influence of alcohol or drugs may be eligible for treatment services for their problem rather than serving time in prison. The judge may even order that the individual receive rehab, either alone or in addition to other sentencing. First time offenders specifically will often be given the opportunity to go with a criminal justice client rehab rather than other sentencing, and it is highly recommended that they reap the benefits of it when it is a choice. The idea behind criminal justice client rehabs is it is much more efficient and effective to invest effort and time into rehabilitation than punishment. Much research has been done to see how effective this strategy is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehabilitation. The signs and indicators appear to be quite positive, and criminal justice clients who experience treatment have a much better chance of remaining out of the judicial system following treatment.
