Criminal justice client rehabs are available as a significantly better option than prison time or significant fines for individuals who have already been convicted of any type of drug or alcohol related crime. By way of example, someone who has been found guilty of dui of drugs or alcohol may be eligible for treatment services for problem rather than serving time in jail. The judge may even order the individual receive treatment, either alone or as well as other consequences. First-time offenders in particular are often given the opportunity to go with a criminal justice client rehab instead of 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 far more effective and efficient to invest time and effort into treatment than punishment. Much research has been done to find out how effective this approach 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 that do experience rehabilitation have better potential for remaining out of the system after treatment.
