Criminal justice client rehabs can be considered like a considerably better option than time in jail or significant fines for those who have been convicted of any kind of drug or alcohol related crime. By way of example, a person who has been found guilty of driving under the influence of drugs or alcohol may be eligible to receive rehab services because of their problem rather than serving time in prison. The judge might order that the individual receive rehabilitation, either alone or together with other consequences. First-time offenders in particular will often be given the ability to choose a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended 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 discover how effective this method is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehabilitation. All indicators seem to be quite positive, and criminal justice clients that experience rehabilitation have a better chance of remaining out of the system following rehabilitation.
