Criminal justice client rehabs are available as a far better option than prison time or significant fines for many who have already been convicted of any sort of alcohol or drug related crime. By way of example, someone who has been in prison for driving drunk of drugs or alcohol may qualify to receive rehab services for their problem rather than serving time in jail. The judge could even order that the individual receive rehabilitation, either alone or in addition to other sentencing. First-time offenders in particular tend to be given the chance to select a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended they take advantage of it if it's a possibility. The concept behind criminal justice client rehabs is it is much more efficient and effective to invest time and energy into rehabilitation than enforcement of other consequences. Much research has been carried out to see how effective this method is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following treatment. The signs and indicators seem quite positive, and criminal justice clients who do take part in treatment have a better probability of remaining out of the system after treatment.
