Criminal justice client rehabs are available being a significantly better option than time in jail or heavy fines for individuals who have already been convicted of any kind of drug or alcohol related crime. By way of example, anyone who has been in prison for dui of drugs or alcohol may be eligible to obtain rehabilitation services for his or her problem instead of serving time in jail. The judge could even order that the individual receive rehabilitation, either alone or along with other consequences. First time offenders in particular are often given the ability to pick a criminal justice client rehab instead of other sentencing, and it is highly recommended that they make the most of it when it is a possibility. The theory behind criminal justice client rehabs is that it is far more effective and efficient to invest commitment into rehab than enforcement of other consequences. Much research has been completed to discover how effective this approach is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following treatment. All indicators appear to be quite positive, and criminal justice clients that do experience rehab have a much better probability of remaining out of the judicial system after rehab.
