Criminal justice client rehabs are available like a far better option than time in jail or significant fines for many who have already been convicted of any kind of drug or alcohol related crime. By way of example, a person who has been found guilty of driving under the influence of alcohol or drugs may be eligible for treatment services because of their problem as an alternative to serving time in jail. The judge may even order the individual receive rehabilitation, either alone or in addition to other sentencing. First time offenders in particular are often given the opportunity choose a criminal justice client rehab instead of other sentencing, and it is well-advised they benefit from it if it is an alternative. The theory behind criminal justice client rehabs is that it is far more effective and efficient to invest time and effort into rehabilitation than enforcement of other consequences. Much research has been done to see how effective this process is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehabilitation. All indicators seem quite positive, and criminal justice clients who do experience rehabilitation have a better probability of remaining out of the judicial system following rehab.
