Criminal justice client rehabs can be considered being a significantly better option than incarceration or heavy fines for those who have already been convicted of any type of alcohol or drug related crime. For example, somebody who has been in prison for dui of alcohol or drugs may be eligible to get treatment services for problem instead of serving time in prison. The judge may even order the individual receive treatment, either alone or along with other consequences. First time offenders specifically will often be given the ability to choose a criminal justice client rehab instead of other sentencing, and it is well-advised they reap the benefits of it when it is an option. The concept behind criminal justice client rehabs is it is much more effective and efficient to invest time and energy into rehabilitation than punishment. Much research has been carried out to discover how effective this process is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehabilitation. The signs and indicators appear to be quite positive, and criminal justice clients that take part in treatment have better probability of remaining out of the system following treatment.
