Criminal justice client rehabs are available being a significantly better option than time in jail or heavy fines for those who have already been convicted of any kind of drug or alcohol related crime. For instance, a person who has been found guilty of driving drunk of alcohol or drugs may be eligible for rehab services for their problem instead of serving time in prison. The judge may even order that the individual receive rehab, either alone or together with other sentencing. Very first time offenders in particular in many cases are given the opportunity to pick a criminal justice client rehab as opposed to other sentencing, and it is highly recommended they benefit from it if it is an option. 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 completed to see how effective this strategy is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehabilitation. All indicators appear to be quite positive, and criminal justice clients that do take part in rehabilitation have better possibility of remaining out of the judicial system following rehab.
