Criminal justice client rehabs are available like a far better option than prison time or heavy fines for those who have already been convicted of any sort of drug or alcohol related crime. For example, somebody who has been found guilty of dui of alcohol or drugs may qualify to get treatment services for problem rather than serving time in jail. The judge could even order the individual receive rehabilitation, either alone or together with other consequences. First time offenders in particular will often be given the chance to select a criminal justice client rehab as opposed to other sentencing, and it is well-advised that they take advantage of it when it is a possibility. The idea behind criminal justice client rehabs is that it is much more effective and efficient to invest time and energy into treatment than punishment. Much research has been done to find out how effective this method is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following treatment. All indicators seem quite positive, and criminal justice clients that do take part in rehabilitation have a much better potential for remaining out of the system after rehabilitation.
