Criminal justice client rehabs are available as a significantly better option than prison time or significant fines for many 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 drunk of drugs or alcohol may be eligible to get rehab services for their problem as opposed to serving time in jail. The judge might even order the individual receive rehabilitation, either alone or as well as other consequences. First-time offenders in particular are often given the opportunity to select a criminal justice client rehab instead of other sentencing, and it is well-advised they benefit from it if it is a possibility. The concept behind criminal justice client rehabs is it is much more effective and efficient to invest effort and time into treatment than enforcement of other consequences. Much research has been carried out to find out how effective this approach is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehab. All indicators seem to be quite positive, and criminal justice clients who take part in treatment have better probability of remaining out of the system following rehab.
