Criminal justice client rehabs can be considered like a far better option than time in jail or heavy fines for those who have already been convicted of any kind of drug or alcohol related crime. For example, someone who has been in prison for driving under the influence of drugs or alcohol may be eligible for treatment services for problem as an alternative to serving time in prison. The judge might even order the individual receive rehabilitation, either alone or as well as other sentencing. First-time offenders specifically are often given the chance to select a criminal justice client rehab rather than other sentencing, and it is highly recommended they take advantage of it if it is a choice. The concept behind criminal justice client rehabs is it is way more effective and efficient to invest effort and time into treatment than punishment. Much research has been done to observe 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 seem to be quite positive, and criminal justice clients who experience rehabilitation have a better chance of remaining out of the judicial system following treatment.
