Criminal justice client rehabs are available like a significantly better option than incarceration or significant fines for those who have already been convicted of any type of drug or alcohol related crime. As an example, someone who has been in prison for driving under the influence of drugs or alcohol may be eligible to receive rehab services for problem as opposed to serving time in jail. The judge could even order that the individual receive rehab, either alone or as well as other sentencing. First time offenders specifically will often be given the chance to select a criminal justice client rehab as opposed to other sentencing, and it is well-advised they benefit from it when it is an alternative. The idea behind criminal justice client rehabs is that it is far more effective and efficient to invest effort and time into treatment than punishment. Much research has been done to see how effective this process 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 do take part in rehab have a better possibility of remaining out of the system after treatment.
