Criminal justice client rehabs can be considered being a far better option than jail time or heavy fines for many who have already been convicted of any kind of alcohol or drug related crime. For instance, a person who has been in prison for driving under the influence of drugs or alcohol may be eligible to obtain rehabilitation services because of their problem rather than serving time in prison. The judge might order the individual receive rehabilitation, either alone or in addition to other consequences. First-time offenders in particular in many cases are given the opportunity pick a criminal justice client rehab rather than other sentencing, and it is highly recommended they take advantage of it when it is an alternative. The theory behind criminal justice client rehabs is it is far more effective and efficient to invest effort and time into rehabilitation than enforcement of other consequences. Much research has been completed to observe how effective this approach is on recidivism rates, i.e. if the individual returns or not to criminal justice system following treatment. The signs and indicators appear to be quite positive, and criminal justice clients that experience rehabilitation have better probability of remaining out of the system following rehab.
