Criminal justice client rehabs are available as a far better option than jail time or significant fines for those who have been convicted of any sort of drug or alcohol related crime. As an example, someone who has been found guilty of driving drunk of drugs or alcohol may be eligible to get rehab services because of their problem instead of serving time in prison. The judge might order that the individual receive rehabilitation, either alone or along with other consequences. Very first time offenders specifically will often be given the ability to pick a criminal justice client rehab as opposed to other sentencing, and it is well-advised that they take advantage of it when it is a choice. The theory behind criminal justice client rehabs is that it is far more efficient and effective to invest time and energy into rehabilitation than punishment. Much research has been completed to find out how effective this method is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehabilitation. The signs and indicators appear to be quite positive, and criminal justice clients who take part in rehabilitation have a better chance of remaining out of the system after rehabilitation.
