Criminal justice client rehabs are available like a far better option than time in jail or heavy fines for those who have already been convicted of any kind of alcohol or drug related crime. For example, someone who has been found guilty of driving under the influence of drugs or alcohol may be eligible to obtain rehab services for his or her problem instead of serving time in jail. The judge may even order that the individual receive rehabilitation, either alone or along with other consequences. First time offenders specifically will often be given the opportunity to pick a criminal justice client rehab as opposed to other sentencing, and it is highly recommended that they take advantage of it when it is an alternative. The theory behind criminal justice client rehabs is that it is much more effective and efficient to invest commitment into rehab than enforcement of other consequences. Much research has been completed to see how effective this process is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehabilitation. All indicators seem to be quite positive, and criminal justice clients that take part in treatment have a much better chance of remaining out of the judicial system following treatment.
