Criminal justice client rehabs are available being 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. By way of example, anyone who has been in prison for driving under the influence of alcohol or drugs may be eligible to obtain rehab services for his or her problem as opposed to serving time in jail. The judge might even order that the individual receive rehab, either alone or along with other sentencing. First-time offenders in particular in many cases are given the chance to pick a criminal justice client rehab as an alternative to other sentencing, and it is well-advised they benefit from it if it is an option. The concept behind criminal justice client rehabs is that it is far more efficient and effective to invest commitment into treatment than enforcement of other consequences. Much research has been completed 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. All indicators appear to be quite positive, and criminal justice clients that do take part in rehab have a better chance of remaining out of the judicial system following rehab.
