Criminal justice client rehabs are available being a far better option than incarceration or significant fines for those who have been convicted of any sort of drug or alcohol related crime. For instance, someone who has been found guilty of driving under the influence of drugs or alcohol may qualify for rehabilitation services for his or her problem instead of serving time in jail. The judge could even order the individual receive rehabilitation, either alone or along with other sentencing. Very first time offenders specifically tend to be given the opportunity to choose a criminal justice client rehab as an alternative to other sentencing, and it is well-advised that they benefit from it if it is an alternative. The theory behind criminal justice client rehabs is that it is far more efficient and effective to invest effort and time into rehabilitation than enforcement of other consequences. Much research has been done to find out how effective this strategy is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehabilitation. The signs and indicators seem to be quite positive, and criminal justice clients that do take part in treatment have a better chance of remaining out of the system following rehabilitation.
