Criminal justice client rehabs can be considered as being a far better option than time in jail or heavy fines for many who have already been convicted of any type of drug or alcohol related crime. By way of example, somebody who has been in prison for dui of drugs or alcohol may be eligible to receive rehabilitation services for his or her problem as an alternative to serving time in jail. The judge could even order that the individual receive rehab, either alone or in addition to other consequences. First time offenders in particular will often be given the chance to pick a criminal justice client rehab rather than other sentencing, and it is highly recommended they take advantage of it if it is an alternative. The concept behind criminal justice client rehabs is that it is far more efficient and effective to invest time and effort into treatment than punishment. Much research has been done to observe how effective this method is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehabilitation. All indicators seem to be quite positive, and criminal justice clients who take part in rehab have better probability of remaining out of the system after treatment.
