Criminal justice client rehabs can be considered being a far better option than prison time or heavy fines for individuals who have already been convicted of any sort of alcohol or drug related crime. For example, a person who has been found guilty of driving while impaired of alcohol or drugs may be eligible to obtain treatment services for problem instead of serving time in prison. The judge could even order the individual receive rehabilitation, either alone or in addition to other consequences. New offenders in particular are often given the opportunity to choose a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended 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 done 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 that do experience rehab have better potential for remaining out of the system following rehab.
