Criminal justice client rehabs can be considered like a far better option than jail time or significant fines for many who have already been convicted of any kind of drug or alcohol related crime. For example, anyone who has been in prison for driving under the influence of alcohol or drugs may qualify for rehab services for his or her problem as an alternative to serving time in prison. The judge might even order that the individual receive rehabilitation, either alone or as well as other sentencing. Very first time offenders in particular are often given the ability to go with a criminal justice client rehab as opposed to other sentencing, and it is highly recommended that they reap the benefits of it when it is a choice. The theory behind criminal justice client rehabs is that it is way more efficient and effective to invest effort and time into rehab than enforcement of other consequences. Much research has been carried out to observe how effective this process is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following treatment. All indicators seem quite positive, and criminal justice clients that experience rehabilitation have a better chance of remaining out of the system after rehab.
