Criminal justice client rehabs can be considered being a considerably better option than time in jail 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 drugs or alcohol may be eligible to get rehabilitation services for their problem as an alternative to serving time in prison. The judge may even order that the individual receive rehab, either alone or in addition to other sentencing. First time offenders in particular will often be given the opportunity to choose a criminal justice client rehab rather than other sentencing, and it is well-advised they take advantage of it if it's a possibility. The theory behind criminal justice client rehabs is it is way more efficient and effective to invest effort and time into rehab than enforcement of other consequences. Much research has been carried out to observe how effective this process is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following treatment. All indicators seem to be quite positive, and criminal justice clients who do experience rehab have a better probability of remaining out of the judicial system following rehabilitation.
