Criminal justice client rehabs can be considered as being a far better option than incarceration or significant fines for individuals who have already been convicted of any type of drug or alcohol related crime. For instance, somebody who has been in prison for driving under the influence of drugs or alcohol may qualify to get rehabilitation services for their problem instead of serving time in prison. The judge may even order that the individual receive rehabilitation, either alone or together with other sentencing. Very first time offenders in particular will often be given the ability to go with a criminal justice client rehab rather than other sentencing, and it is highly recommended they take advantage of it if it is a possibility. The concept behind criminal justice client rehabs is it is much more effective and efficient to invest time and energy into treatment than enforcement of other consequences. Much research has been done to see how effective this process is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehab. All indicators seem quite positive, and criminal justice clients that take part in rehab have a better probability of remaining out of the system following rehabilitation.
