Criminal justice client rehabs are available as a far better option than incarceration or significant fines for those who have already been convicted of any sort of drug or alcohol related crime. For instance, a person who has been found guilty of driving while impaired of drugs or alcohol may be eligible to get rehabilitation services for their problem as opposed to serving time in jail. The judge might order that the individual receive rehabilitation, either alone or together with other sentencing. New offenders specifically in many cases are given the chance to choose a criminal justice client rehab rather than other sentencing, and it is highly recommended that they benefit from it if it is an alternative. The idea behind criminal justice client rehabs is it is much more effective and efficient to invest time and effort into treatment than punishment. Much research has been done to see 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 take part in rehab have better potential for remaining out of the judicial system after treatment.
