Criminal justice client rehabs are available as a significantly better option than prison time or significant fines for those who have been convicted of any type of alcohol or drug related crime. By way of example, someone who has been found guilty of dui of drugs or alcohol may qualify for treatment services for his or her problem rather than serving time in jail. The judge may even order the individual receive rehabilitation, either alone or in addition to other sentencing. Very first time offenders in particular tend to be given the ability 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 far more efficient and effective to invest effort and time into rehab than enforcement of other consequences. Much research has been done to discover how effective this approach is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following treatment. All indicators seem quite positive, and criminal justice clients who experience rehab have better chance of remaining out of the system after rehabilitation.
