Criminal justice client rehabs are available as a far better option than jail time or heavy fines for individuals who have been convicted of any kind of drug or alcohol related crime. As an example, a person who has been found guilty of dui of alcohol or drugs may qualify to receive treatment services for their problem rather than serving time in jail. The judge might order that the individual receive rehab, either alone or along with other sentencing. First time offenders in particular will often be given the chance to select a criminal justice client rehab rather than other sentencing, and it is well-advised that they make the most of it if it is an alternative. The concept behind criminal justice client rehabs is that it is much more efficient and effective to invest time and energy into rehabilitation than enforcement of other consequences. Much research has been carried out to see how effective this process is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehabilitation. All indicators appear to be quite positive, and criminal justice clients who experience rehabilitation have better possibility of remaining out of the system after rehabilitation.
