Criminal justice client rehabs can be considered like a far better option than prison time or significant fines for those who have been convicted of any sort of drug or alcohol related crime. For instance, someone who has been found guilty of driving drunk of drugs or alcohol may qualify for treatment services for their problem rather than serving time in jail. The judge may even order that the individual receive treatment, either alone or together with other sentencing. First time offenders specifically in many cases are given the ability to select a criminal justice client rehab rather than other sentencing, and it is highly recommended that they benefit from it if it is an alternative. The theory behind criminal justice client rehabs is that it is far more efficient and effective to invest effort and time into rehab than enforcement of other consequences. Much research has been completed to observe 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 to be quite positive, and criminal justice clients that do experience rehab have better chance of remaining out of the judicial system following treatment.
