Criminal justice client rehabs can be considered as being a considerably better option than incarceration or heavy fines for those who have already been convicted of any type of alcohol or drug related crime. For instance, somebody who has been found guilty of driving drunk of alcohol or drugs may be eligible for rehabilitation services for problem as opposed to serving time in jail. The judge might order that the individual receive rehabilitation, either alone or in addition to other consequences. First-time offenders in particular are often given the chance to choose a criminal justice client rehab rather than other sentencing, and it is highly recommended that they take advantage of it if it is a possibility. The theory behind criminal justice client rehabs is that it is far more effective and efficient to invest effort and time into treatment than punishment. Much research has been done to find out how effective this process is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehab. The signs and indicators appear to be quite positive, and criminal justice clients who do experience rehabilitation have a better probability of remaining out of the judicial system after treatment.
