Criminal justice client rehabs can be considered as a far better option than prison time or heavy fines for those who have already been convicted of any kind of alcohol or drug related crime. As an example, someone who has been found guilty of driving while impaired of drugs or alcohol may qualify to get rehabilitation services for their problem rather than serving time in jail. The judge might even order the individual receive rehabilitation, either alone or along with other sentencing. First-time offenders specifically in many cases are given the opportunity to pick a criminal justice client rehab as an alternative to other sentencing, and it is well-advised they make the most of it if it is a choice. The theory behind criminal justice client rehabs is that it is far more efficient and effective to invest effort and time into treatment than enforcement of other consequences. Much research has been done to see how effective this strategy is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehabilitation. All indicators seem quite positive, and criminal justice clients who do experience rehabilitation have a much better possibility of remaining out of the system following rehabilitation.
