Criminal justice client rehabs are available as being a considerably better option than time in jail or heavy fines for individuals who have been convicted of any type of drug or alcohol related crime. As an example, a person who has been in prison for dui of alcohol or drugs may qualify for rehabilitation services for his or her problem as an alternative to serving time in jail. The judge might order the individual receive rehab, either alone or in addition to other consequences. First time offenders in particular in many cases are given the chance to choose a criminal justice client rehab rather than other sentencing, and it is well-advised that they take advantage of it if it's a choice. The theory behind criminal justice client rehabs is it is far more effective and efficient to invest effort and time into rehabilitation than punishment. Much research has been carried out to discover how effective this approach is on recidivism rates, i.e. if the individual returns or not to criminal justice system following treatment. The signs and indicators seem to be quite positive, and criminal justice clients who do experience treatment have better possibility of remaining out of the system after rehabilitation.
