Criminal justice client rehabs can be considered being a significantly better option than jail time or heavy fines for those who have been convicted of any kind of drug or alcohol related crime. By way of example, someone who has been in prison for driving while impaired of alcohol or drugs may be eligible to get rehabilitation services for his or her problem as opposed to serving time in prison. The judge could even order that the individual receive rehabilitation, either alone or as well as other consequences. First time offenders specifically will often be given the opportunity select a criminal justice client rehab as opposed to other sentencing, and it is well-advised that they make the most of it when it is a possibility. The theory 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 observe how effective this approach is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehabilitation. The signs and indicators appear to be quite positive, and criminal justice clients who do experience rehabilitation have a better chance of remaining out of the system following treatment.
