Criminal justice client rehabs can be considered being a considerably better option than jail time or significant fines for those who have already been convicted of any kind of drug or alcohol related crime. By way of example, somebody who has been in prison for dui of drugs or alcohol may qualify to obtain rehab services for his or her problem rather than serving time in prison. The judge could even order the individual receive rehabilitation, either alone or in addition to other consequences. First time offenders in particular in many cases are given the ability to choose a criminal justice client rehab as an alternative to other sentencing, and it is well-advised they take advantage of it if it is a choice. The concept behind criminal justice client rehabs is that it is way more effective and efficient to invest effort and time into treatment than punishment. Much research has been carried out to see how effective this approach is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehabilitation. The signs and indicators seem quite positive, and criminal justice clients who do experience treatment have a better possibility of remaining out of the system after rehabilitation.
