Criminal justice client rehabs are available being a far better option than jail time or heavy fines for individuals who have been convicted of any type of alcohol or drug related crime. By way of example, a person who has been found guilty of driving while impaired of alcohol or drugs may be eligible to obtain rehabilitation services for their problem instead of serving time in jail. The judge may even order that the individual receive rehab, either alone or together with other consequences. First time offenders in particular in many cases are given the ability to select a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended they take advantage of it if it is an option. The theory behind criminal justice client rehabs is it is far more effective and efficient to invest time and effort into rehab than enforcement of other consequences. Much research has been done to discover how effective this approach is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehabilitation. The signs and indicators seem to be quite positive, and criminal justice clients that experience rehabilitation have better potential for remaining out of the system following treatment.
