Criminal justice client rehabs are available like a significantly 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, somebody who has been in prison for driving drunk of alcohol or drugs may be eligible for treatment services because of their problem rather than serving time in jail. The judge could even order that the individual receive rehabilitation, either alone or as well as other sentencing. New offenders in particular are often given the opportunity to pick a criminal justice client rehab as an alternative to other sentencing, and it is well-advised they reap the benefits of it if it's an option. The theory behind criminal justice client rehabs is it is way more effective and efficient to invest time and effort into rehab than punishment. Much research has been carried out to observe how effective this approach is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following treatment. The signs and indicators seem to be quite positive, and criminal justice clients who experience rehab have a better chance of remaining out of the system after rehab.
