Criminal justice client rehabs are available being a considerably better option than time in jail or significant fines for many who have been convicted of any type of drug or alcohol related crime. As an example, anyone who has been in prison for driving under the influence of alcohol or drugs may qualify to obtain rehab services for his or her problem rather than serving time in jail. The judge might even order that the individual receive treatment, either alone or as well as other consequences. First-time offenders specifically tend to be given the chance to select a criminal justice client rehab as opposed to other sentencing, and it is well-advised that they take advantage of it if it is an alternative. The idea behind criminal justice client rehabs is it is far more effective and efficient to invest effort and time into rehab than enforcement of other consequences. Much research has been carried out to observe how effective this strategy is on recidivism rates, i.e. if the individual returns or not to criminal justice system following treatment. All indicators seem to be quite positive, and criminal justice clients that take part in rehabilitation have a much better chance of remaining out of the system after treatment.
