Criminal justice client rehabs can be considered as a significantly better option than prison time or significant fines for those who have been convicted of any sort of drug or alcohol related crime. As an example, anyone who has been in prison for driving while impaired of drugs or alcohol may qualify for treatment services for problem as opposed to serving time in jail. The judge may even order the individual receive rehabilitation, either alone or along with other sentencing. First-time offenders in particular in many cases are given the opportunity to select a criminal justice client rehab as opposed to other sentencing, and it is well-advised they take advantage of it when it is an option. The idea behind criminal justice client rehabs is it is much more efficient and effective to invest effort and time into rehabilitation than punishment. Much research has been carried out to see how effective this process is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehab. The signs and indicators appear to be quite positive, and criminal justice clients that do take part in rehab have a much better potential for remaining out of the system following rehab.
