Criminal justice client rehabs are available as a far better option than jail time or significant fines for individuals who have been convicted of any type of drug or alcohol related crime. For example, someone who has been in prison for driving while impaired of drugs or alcohol may be eligible to get treatment services for his or her problem rather than serving time in prison. The judge might even order that the individual receive treatment, either alone or in addition to other sentencing. Very first time offenders specifically tend to be given the opportunity to choose a criminal justice client rehab as an alternative to other sentencing, and it is well-advised they take advantage of it when it is an alternative. The idea behind criminal justice client rehabs is it is far more efficient and effective to invest time and energy into rehabilitation than enforcement of other consequences. Much research has been completed to find out how effective this strategy is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehabilitation. The signs and indicators seem to be quite positive, and criminal justice clients who do take part in rehabilitation have a better probability of remaining out of the system after rehab.
