Criminal justice client rehabs are available as a considerably better option than jail time or significant fines for those who have already been convicted of any sort of drug or alcohol related crime. For instance, anyone who has been found guilty of driving under the influence of alcohol or drugs may be eligible to obtain rehab services because of their problem instead of serving time in jail. The judge could even order that the individual receive rehabilitation, either alone or in addition to other consequences. New offenders specifically will often be given the ability to go with a criminal justice client rehab as an alternative to other sentencing, and it is well-advised they make the most of it when it is an alternative. The idea behind criminal justice client rehabs is that it is far more efficient and effective to invest time and energy into treatment than punishment. Much research has been carried out to observe how effective this approach 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 who take part in rehabilitation have better probability of remaining out of the system after rehab.
