Criminal justice client rehabs can be considered like a far better option than time in jail or significant fines for those who have already been convicted of any kind of drug or alcohol related crime. For instance, someone who has been in prison for driving while impaired of drugs or alcohol may qualify for treatment services for their problem as an alternative to serving time in prison. The judge might even order that the individual receive rehabilitation, either alone or in addition to other sentencing. New offenders in particular will often be given the opportunity choose a criminal justice client rehab instead of other sentencing, and it is highly recommended that they make the most of it if it is a possibility. The theory behind criminal justice client rehabs is that it is far more effective and efficient to invest time and effort into treatment than punishment. Much research has been done to observe how effective this strategy is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehab. The signs and indicators seem quite positive, and criminal justice clients who take part in rehabilitation have a better chance of remaining out of the system following rehabilitation.
