Criminal justice client rehabs can be considered as being a considerably better option than prison time or significant fines for those who have been convicted of any type of alcohol or drug related crime. By way of example, somebody who has been in prison for driving under the influence of alcohol or drugs may be eligible to get treatment services because of their problem as an alternative to serving time in jail. The judge may even order the individual receive treatment, either alone or as well as other consequences. First-time offenders in particular are often given the ability to select a criminal justice client rehab rather than other sentencing, and it is highly recommended they make the most of it if it is an option. 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 carried out to find out how effective this method is on recidivism rates, i.e. if the individual returns or not to criminal justice system following treatment. The signs and indicators seem to be quite positive, and criminal justice clients who take part in treatment have better chance of remaining out of the system after treatment.
