Criminal justice client rehabs can be considered like a considerably better option than incarceration or heavy fines for individuals who have already been convicted of any kind of alcohol or drug related crime. For example, someone who has been in prison for driving while impaired of alcohol or drugs may be eligible to obtain rehabilitation services for their problem instead of serving time in jail. The judge could even order that the individual receive rehabilitation, either alone or along with other sentencing. First-time offenders specifically tend to be given the opportunity go with a criminal justice client rehab rather than other sentencing, and it is well-advised that they take advantage of it if it is a possibility. The idea behind criminal justice client rehabs is that it is much more efficient and effective 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. All indicators appear to be quite positive, and criminal justice clients who do take part in treatment have better probability of remaining out of the judicial system following rehabilitation.
