Criminal justice client rehabs are available being a significantly better option than prison time or heavy fines for those who have been convicted of any kind of drug or alcohol related crime. For instance, a person who has been in prison for dui of drugs or alcohol may qualify for rehabilitation services for his or her problem as opposed to serving time in prison. The judge might order the individual receive rehab, either alone or along with other consequences. Very first time offenders specifically tend to be given the opportunity choose a criminal justice client rehab rather than other sentencing, and it is highly recommended they take advantage of it if it is an option. The theory behind criminal justice client rehabs is that it is way more effective and efficient to invest effort and time into rehab than enforcement of other consequences. Much research has been carried out to observe how effective this strategy 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 to be quite positive, and criminal justice clients who do take part in rehabilitation have better probability of remaining out of the system after rehab.
