Criminal justice client rehabs are available like a considerably better option than jail time or heavy fines for those who have already been convicted of any type of drug or alcohol related crime. For example, somebody who has been in prison for driving under the influence of alcohol or drugs may be eligible to receive rehab services for their problem as an alternative to serving time in prison. The judge might even order the individual receive rehabilitation, either alone or along with other sentencing. First-time offenders specifically tend to be given the ability to pick a criminal justice client rehab as opposed to other sentencing, and it is well-advised they take advantage of it if it is an alternative. The concept behind criminal justice client rehabs is it is far more effective and efficient to invest effort and time into rehabilitation than punishment. Much research has been completed to find out 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 take part in rehab have a better possibility of remaining out of the judicial system after rehab.
