Criminal justice client rehabs are available as being a considerably better option than time in jail 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 drunk of alcohol or drugs may qualify to receive rehab services for his or her problem as an alternative to serving time in jail. The judge may even order that the individual receive rehab, either alone or together with other consequences. First time offenders specifically will often be given the opportunity to choose a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended that they make the most of it if it is an alternative. The theory behind criminal justice client rehabs is that it is way more efficient and effective to invest time and effort into treatment than enforcement of other consequences. Much research has been completed to see 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 do take part in rehab have a much better potential for remaining out of the system after rehab.
