Criminal justice client rehabs can be considered like a considerably better option than prison time or significant fines for individuals who have already been convicted of any type of alcohol or drug related crime. For example, someone who has been found guilty of driving while impaired of alcohol or drugs may be eligible for treatment services because of their problem as an alternative to serving time in prison. The judge could even order that the individual receive rehabilitation, either alone or together with other sentencing. Very first time offenders in particular are often given the ability to choose a criminal justice client rehab rather than other sentencing, and it is well-advised that they reap the benefits 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 discover how effective this method is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following treatment. All indicators seem quite positive, and criminal justice clients that take part in treatment have better probability of remaining out of the judicial system following rehab.
