Criminal justice client rehabs can be considered as a far better option than time in jail or heavy fines for those who have already been convicted of any kind of drug or alcohol related crime. For instance, somebody who has been in prison for driving while impaired of alcohol or drugs may be eligible to receive treatment services for his or her problem as opposed to serving time in jail. The judge may even order that the individual receive treatment, either alone or in addition to other sentencing. New offenders in particular will often be given the opportunity to choose a criminal justice client rehab rather than other sentencing, and it is highly recommended that they reap the benefits of it when it is an option. The idea behind criminal justice client rehabs is it is way more effective and efficient to invest effort and time into rehab than enforcement of other consequences. Much research has been completed to find out how effective this approach is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehabilitation. All indicators appear to be quite positive, and criminal justice clients who do experience treatment have better potential for remaining out of the system following treatment.
