Criminal justice client rehabs are available as being a far better option than prison time or heavy fines for individuals who have already been convicted of any sort of drug or alcohol related crime. For example, a person who has been in prison for driving while impaired of alcohol or drugs may be eligible to obtain treatment services for problem rather than serving time in prison. The judge may even order the individual receive rehab, either alone or in addition to other consequences. Very first time offenders in particular will often be given the chance to choose a criminal justice client rehab rather than other sentencing, and it is well-advised they benefit from it when it is an alternative. The theory behind criminal justice client rehabs is it is way more effective and efficient to invest effort and time into treatment than enforcement of other consequences. Much research has been completed to observe how effective this strategy is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehab. The signs and indicators appear to be quite positive, and criminal justice clients who do take part in rehab have a much better chance of remaining out of the judicial system after rehab.
