Criminal justice client rehabs can be considered as being a considerably better option than jail time or significant fines for those who have been convicted of any sort of drug or alcohol related crime. By way of example, a person who has been in prison for driving while impaired of drugs or alcohol may qualify to obtain rehab services for his or her problem rather than serving time in prison. The judge might order the individual receive rehabilitation, either alone or in addition to other consequences. First time offenders in particular in many cases are given the chance to select a criminal justice client rehab instead of other sentencing, and it is highly recommended they take advantage of it if it is a choice. The concept behind criminal justice client rehabs is that it is way more effective and efficient to invest effort and time into treatment than punishment. Much research has been done to observe how effective this method is on recidivism rates, i.e. if the individual 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 better potential for remaining out of the system after treatment.
