Criminal justice client rehabs are available as being a considerably better option than incarceration or significant fines for individuals who have already been convicted of any sort of drug or alcohol related crime. For instance, someone who has been in prison for driving while impaired of drugs or alcohol may be eligible to get treatment services because of their problem instead of serving time in jail. The judge might even order the individual receive treatment, either alone or as well as other consequences. Very first time offenders in particular will often be given the chance to pick a criminal justice client rehab rather than other sentencing, and it is well-advised that they benefit from it if it is a possibility. The theory behind criminal justice client rehabs is that it is much more effective and efficient to invest effort and time into rehab than enforcement of other consequences. Much research has been done 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 rehab. All indicators seem quite positive, and criminal justice clients who experience rehab have a better potential for remaining out of the system after rehabilitation.
