Criminal justice client rehabs can be considered as being a significantly better option than prison time or significant fines for individuals who have already been convicted of any kind of alcohol or drug related crime. For example, a person who has been found guilty of driving under the influence of alcohol or drugs may be eligible to get rehab services for problem rather than serving time in jail. The judge may even order that the individual receive rehabilitation, either alone or together with other sentencing. First time offenders specifically will often be given the ability to select a criminal justice client rehab rather than other sentencing, and it is well-advised that they benefit from it when it is a possibility. The concept behind criminal justice client rehabs is it is far more efficient and effective to invest commitment into rehabilitation than punishment. Much research has been carried out to find out how effective this strategy is on recidivism rates, i.e. if the individual returns or not to criminal justice system following treatment. The signs and indicators appear to be quite positive, and criminal justice clients that experience treatment have better chance of remaining out of the judicial system after treatment.
