Criminal justice client rehabs are available like a far better option than time in jail or significant fines for those who have already been convicted of any type 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 to get treatment services for problem as opposed to serving time in prison. The judge could even order the individual receive rehab, either alone or together with other consequences. First-time offenders in particular in many cases are given the chance to choose a criminal justice client rehab rather than other sentencing, and it is well-advised that they make the most of it if it's an alternative. The theory behind criminal justice client rehabs is it is much more efficient and effective to invest effort and time into rehab than enforcement of other consequences. Much research has been done 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 to be quite positive, and criminal justice clients that experience rehab have a better probability of remaining out of the judicial system after rehab.
