Criminal justice client rehabs are available as a considerably better option than jail time or heavy fines for those who have already been convicted of any sort of drug or alcohol related crime. For example, somebody who has been found guilty of driving while impaired of drugs or alcohol may qualify for rehab services for their problem as opposed to serving time in jail. The judge might even order the individual receive rehabilitation, either alone or as well as other sentencing. First time offenders in particular will often be given the ability to choose a criminal justice client rehab instead of other sentencing, and it is highly recommended they reap the benefits of it if it is a possibility. The idea behind criminal justice client rehabs is it is far more effective and efficient to invest time and effort into rehabilitation than enforcement of other consequences. Much research has been carried out to discover how effective this strategy is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehabilitation. All indicators appear to be quite positive, and criminal justice clients that take part in rehabilitation have a much better probability of remaining out of the system following rehabilitation.
