Criminal justice client rehabs are available as being a considerably better option than incarceration or heavy fines for individuals who have already been convicted of any kind of drug or alcohol related crime. As an example, anyone who has been found guilty of driving under the influence of drugs or alcohol may qualify to get treatment services for their problem as an alternative to serving time in prison. The judge might even order the individual receive rehabilitation, either alone or as well as other sentencing. First time offenders in particular in many cases are given the opportunity go with 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 alternative. The idea behind criminal justice client rehabs is it is much more effective and efficient to invest effort and time into rehabilitation than punishment. Much research has been carried out to observe 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 a better probability of remaining out of the system following rehab.
