Criminal justice client rehabs are available being a considerably better option than prison time or heavy fines for those who have been convicted of any sort of drug or alcohol related crime. By way of example, someone who has been in prison for dui of drugs or alcohol may be eligible to get rehabilitation services because of their problem as an alternative to serving time in prison. The judge could even order that the individual receive rehab, either alone or as well as other sentencing. First time offenders in particular tend to be given the ability to pick a criminal justice client rehab instead of other sentencing, and it is well-advised they reap the benefits of it if it is a possibility. The theory behind criminal justice client rehabs is that it is way more effective and efficient to invest time and energy into treatment than punishment. Much research has been completed to observe how effective this approach is on recidivism rates, i.e. if the individual returns or not to criminal justice system following treatment. The signs and indicators seem quite positive, and criminal justice clients who take part in rehabilitation have better potential for remaining out of the system following rehab.
