Criminal justice client rehabs can be considered as being a far better option than prison time or significant fines for individuals who have already been convicted of any type of drug or alcohol related crime. For example, a person who has been in prison for driving under the influence of drugs or alcohol may be eligible to receive rehab services for problem rather than serving time in jail. The judge may 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 opportunity to go with a criminal justice client rehab instead of other sentencing, and it is well-advised that they make the most of it when it is an alternative. The idea behind criminal justice client rehabs is it is way more effective and efficient to invest effort and time into rehabilitation than enforcement of other consequences. Much research has been done to see how effective this approach is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehab. The signs and indicators seem quite positive, and criminal justice clients who experience treatment have better possibility of remaining out of the system after rehab.
