Criminal justice client rehabs can be considered as being a far better option than time in jail or heavy fines for individuals who have been convicted of any type of drug or alcohol related crime. By way of example, a person who has been in prison for driving under the influence of alcohol or drugs may qualify to get rehab services for his or her problem as opposed to serving time in prison. The judge may even order the individual receive rehabilitation, either alone or as well as other consequences. First-time offenders in particular tend to be given the opportunity pick a criminal justice client rehab rather than other sentencing, and it is well-advised that they make the most of it when it is an alternative. The theory behind criminal justice client rehabs is that it is way more effective and efficient to invest effort and time into treatment than enforcement of other consequences. Much research has been carried out to find out 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 better probability of remaining out of the judicial system following treatment.
