Criminal justice client rehabs are available as being a significantly better option than incarceration or significant fines for those who have been convicted of any kind of drug or alcohol related crime. For example, somebody who has been found guilty of driving drunk of alcohol or drugs may be eligible to receive treatment services for problem as opposed to serving time in jail. The judge may even order the individual receive rehab, either alone or along with other sentencing. New offenders in particular in many cases are given the ability to pick a criminal justice client rehab as opposed to other sentencing, and it is highly recommended they benefit from it if it's an alternative. The theory behind criminal justice client rehabs is it is much more effective and efficient to invest effort and time into rehabilitation than punishment. Much research has been done to observe how effective this process is on recidivism rates, i.e. if the individual returns or not to criminal justice system following treatment. The signs and indicators appear to be quite positive, and criminal justice clients who do take part in rehab have a better potential for remaining out of the system following treatment.
