Criminal justice client rehabs can be considered being a significantly better option than jail time or heavy fines for individuals who have been convicted of any type of alcohol or drug related crime. For example, a person who has been in prison for driving while impaired of alcohol or drugs may qualify to get rehab services because of their problem rather than serving time in prison. The judge could even order the individual receive treatment, either alone or along with other sentencing. Very first time offenders specifically in many cases are given the opportunity to go with a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended that they make the most of it if it is an option. The concept behind criminal justice client rehabs is that it is much more effective and efficient to invest time and energy into rehabilitation than enforcement of other consequences. Much research has been carried out to discover how effective this method is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following treatment. The signs and indicators appear to be quite positive, and criminal justice clients who experience rehabilitation have a much better possibility of remaining out of the system after rehab.
