Criminal justice client rehabs can be considered like a considerably better option than prison time or heavy fines for individuals who have already been convicted of any sort of drug or alcohol related crime. As an example, somebody who has been in prison for driving drunk of alcohol or drugs may be eligible to obtain rehab services for their problem as opposed to serving time in jail. The judge could even order the individual receive rehab, either alone or together with other consequences. New offenders in particular will often be given the ability to choose a criminal justice client rehab as an alternative to other sentencing, and it is well-advised they take advantage of it when it is a possibility. The idea behind criminal justice client rehabs is that 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 discover how effective this approach is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehab. The signs and indicators seem to be quite positive, and criminal justice clients who take part in treatment have better possibility of remaining out of the system following treatment.
