Criminal justice client rehabs are available being a far better option than incarceration or heavy fines for individuals who have already been convicted of any sort of alcohol or drug related crime. For example, someone who has been found guilty of dui of alcohol or drugs may be eligible to get treatment services for problem instead of serving time in prison. The judge could even order that the individual receive rehab, either alone or along with other consequences. First-time offenders in particular in many cases are given the opportunity go with a criminal justice client rehab as opposed to other sentencing, and it is well-advised that they benefit from it when it is an option. The theory behind criminal justice client rehabs is that it is way more efficient and effective to invest time and energy into rehab than punishment. Much research has been done to see how effective this approach is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehab. All indicators appear to be quite positive, and criminal justice clients who take part in treatment have better probability of remaining out of the system following treatment.
