Criminal justice client rehabs can be considered like a far better option than jail time or significant fines for those who have already been convicted of any sort of alcohol or drug related crime. For example, someone who has been in prison for dui of alcohol or drugs may qualify to get treatment services because of their problem instead of serving time in prison. The judge may even order that the individual receive rehabilitation, either alone or in addition to other consequences. Very first time offenders in particular will often be given the chance to go with a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended they take advantage of it if it is an option. The concept behind criminal justice client rehabs is it is way more efficient and effective to invest effort and time into rehab than punishment. Much research has been done to find out how effective this approach is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following treatment. All indicators seem quite positive, and criminal justice clients who do take part in rehab have a better chance of remaining out of the system after treatment.
