Criminal justice client rehabs are available being a significantly better option than prison time or heavy fines for many who have already been convicted of any type of alcohol or drug related crime. For example, someone who has been found guilty of dui of alcohol or drugs may be eligible to get rehabilitation services for his or her problem as an alternative to serving time in jail. The judge might even order that the individual receive rehabilitation, either alone or together with other consequences. First time offenders in particular will often be given the opportunity to select a criminal justice client rehab rather than other sentencing, and it is well-advised they reap the benefits of it if it is a possibility. The theory behind criminal justice client rehabs is that it is much more effective and efficient to invest time and energy into treatment than enforcement of other consequences. Much research has been carried out to see how effective this strategy is on recidivism rates, i.e. if the individual returns or not to criminal justice system following treatment. All indicators seem quite positive, and criminal justice clients that experience rehab have a better probability of remaining out of the judicial system following rehabilitation.
