Criminal justice client rehabs are available as being a far better option than jail time or heavy fines for individuals who have already been convicted of any type of drug or alcohol related crime. By way of example, a person who has been in prison for dui of drugs or alcohol may be eligible to receive rehab services for their problem instead of serving time in prison. The judge could even order the individual receive rehab, either alone or along with other sentencing. New offenders specifically will often be given the ability to pick a criminal justice client rehab as an alternative to other sentencing, and it is well-advised that they take advantage of it if it is a possibility. The idea behind criminal justice client rehabs is that it is much more effective and efficient to invest time and energy into treatment than enforcement of other consequences. Much research has been completed to see how effective this process 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 who do take part in rehab have better probability of remaining out of the system following rehab.
