Criminal justice client rehabs are available as a significantly better option than prison time or heavy fines for many who have been convicted of any type of alcohol or drug related crime. For instance, anyone who has been in prison for dui of alcohol or drugs may be eligible to obtain rehab services for his or her problem as opposed to serving time in prison. The judge might order that the individual receive rehab, either alone or together with other sentencing. First-time offenders in particular tend to be given the opportunity to choose a criminal justice client rehab instead of other sentencing, and it is well-advised that they benefit from it if it is an alternative. The idea behind criminal justice client rehabs is that it is much more effective and efficient to invest commitment into treatment than punishment. Much research has been carried out to find out how effective this approach is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehabilitation. The signs and indicators seem to be quite positive, and criminal justice clients that do experience rehab have a much better chance of remaining out of the system after rehab.
