Criminal justice client rehabs can be considered being a far better option than time in jail or heavy fines for those who have already been convicted of any kind of drug or alcohol related crime. For instance, anyone who has been in prison for driving drunk of drugs or alcohol may be eligible to get rehab services for his or her problem instead of serving time in prison. The judge may even order that the individual receive rehabilitation, either alone or as well as other consequences. New offenders specifically tend to be given the ability to pick a criminal justice client rehab instead of other sentencing, and it is highly recommended that they benefit from it when it is an alternative. The concept behind criminal justice client rehabs is it is far more efficient and effective to invest commitment into rehabilitation than punishment. 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 rehabilitation. The signs and indicators seem to be quite positive, and criminal justice clients who do experience rehab have a much better chance of remaining out of the system after rehab.
