Criminal justice client rehabs can be considered being a considerably better option than incarceration or heavy fines for those who have already been convicted of any type of drug or alcohol related crime. For example, a person who has been in prison for dui of drugs or alcohol may qualify to obtain treatment services because of their problem as opposed to serving time in prison. The judge could even order that the individual receive rehabilitation, either alone or as well as other consequences. First time offenders specifically tend to be given the opportunity to select a criminal justice client rehab rather than other sentencing, and it is highly recommended they take advantage of it if it is an alternative. The concept behind criminal justice client rehabs is that it is much more effective and efficient to invest commitment into treatment than punishment. Much research has been done to observe how effective this approach is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following treatment. All indicators seem to be quite positive, and criminal justice clients who experience rehab have better probability of remaining out of the system following rehabilitation.
