Criminal justice client rehabs are available as a considerably better option than time in jail or heavy fines for those who have been convicted of any kind of alcohol or drug related crime. For example, anyone who has been in prison for driving while impaired of drugs or alcohol may be eligible to receive rehabilitation services for his or her problem as opposed to serving time in jail. The judge could even order that the individual receive rehab, either alone or together with other sentencing. First-time offenders specifically in many cases are given the chance to pick a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended they take advantage of it when it is an option. The theory behind criminal justice client rehabs is it is way more efficient and effective to invest time and effort into rehab than punishment. Much research has been done to find out how effective this strategy is on recidivism rates, i.e. if the individual returns or not to criminal justice system following treatment. The signs and indicators seem quite positive, and criminal justice clients that experience rehabilitation have a much better probability of remaining out of the judicial system following treatment.
