Criminal justice client rehabs are available being a significantly 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. By way of example, someone who has been in prison for driving drunk of drugs or alcohol may qualify for rehab services for their problem as opposed to serving time in jail. The judge could even order the individual receive rehabilitation, either alone or as well as other sentencing. First time offenders in particular will often be given the chance to pick a criminal justice client rehab as an alternative to other sentencing, and it is well-advised that they make the most of it if it is an option. The concept behind criminal justice client rehabs is it is much more efficient and effective to invest time and effort into rehab than punishment. 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 rehabilitation. The signs and indicators seem quite positive, and criminal justice clients that experience rehab have a much better chance of remaining out of the judicial system following rehabilitation.
