Criminal justice client rehabs can be considered like a far better option than jail time or significant fines for many who have already been convicted of any sort of alcohol or drug related crime. As an example, someone who has been in prison for driving drunk of alcohol or drugs may qualify for rehab services for problem instead of serving time in jail. The judge might order that the individual receive rehab, either alone or as well as other sentencing. First-time offenders in particular will often be given the opportunity to choose a criminal justice client rehab as an alternative to other sentencing, and it is well-advised that they benefit from it if it's an alternative. The theory behind criminal justice client rehabs is it is much more efficient and effective to invest effort and time into rehab than enforcement of other consequences. Much research has been done to find out how effective this process is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehabilitation. The signs and indicators appear to be quite positive, and criminal justice clients that do take part in rehab have a better probability of remaining out of the system following rehab.
