Criminal justice client rehabs can be considered like a far better option than jail time or heavy fines for those who have already been convicted of any type of drug or alcohol related crime. As an example, a person who has been in prison for dui of alcohol or drugs may be eligible to get treatment services for his or her problem rather than serving time in jail. The judge may even order the individual receive treatment, either alone or along with other consequences. First-time offenders in particular in many cases are given the opportunity select a criminal justice client rehab rather than other sentencing, and it is highly recommended they reap the benefits of it when it is an alternative. The idea behind criminal justice client rehabs is it is way more effective and efficient to invest effort and time into rehab than enforcement of other consequences. Much research has been carried out 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. The signs and indicators seem quite positive, and criminal justice clients that do experience rehab have a much better potential for remaining out of the judicial system following rehab.
