Criminal justice client rehabs are available as being a far better option than prison time or significant fines for those who have 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 qualify to receive rehab services for his or her problem as opposed to serving time in prison. The judge might even order the individual receive rehab, either alone or together with other consequences. First-time offenders specifically in many cases are given the chance to pick a criminal justice client rehab as opposed to other sentencing, and it is well-advised they take advantage of it if it's an alternative. The theory behind criminal justice client rehabs is that it is way more effective and efficient to invest commitment into rehab 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 rehabilitation. The signs and indicators seem to be quite positive, and criminal justice clients that do take part in rehabilitation have a much better probability of remaining out of the system after rehab.
