Criminal justice client rehabs can be considered as being a far better option than prison time or significant fines for those who have already been convicted of any sort of alcohol or drug related crime. For instance, anyone who has been found guilty of dui of alcohol or drugs may qualify for rehabilitation services for his or her problem as opposed to serving time in prison. The judge might even order that the individual receive rehabilitation, either alone or along with other consequences. First time offenders specifically are often given the chance to pick a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended that they make the most of it when it is a choice. The theory behind criminal justice client rehabs is that it is much more efficient and effective to invest time and energy into rehabilitation than punishment. Much research has been carried out to discover 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 seem to be quite positive, and criminal justice clients that do take part in rehabilitation have a better possibility of remaining out of the system following treatment.
