Criminal justice client rehabs can be considered being a considerably better option than incarceration or significant fines for those who have already been convicted of any sort of drug or alcohol related crime. By way of example, a person who has been in prison for dui of alcohol or drugs may be eligible to get treatment services because of their problem as an alternative to serving time in jail. The judge could even order the individual receive rehabilitation, either alone or as well as other consequences. First-time offenders in particular are often given the opportunity to select a criminal justice client rehab rather than other sentencing, and it is well-advised they benefit from it when it is an alternative. The idea behind criminal justice client rehabs is it is much more efficient and effective to invest effort and time into rehabilitation 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 rehab. The signs and indicators seem quite positive, and criminal justice clients who do experience rehab have a much better possibility of remaining out of the system after treatment.
