Criminal justice client rehabs are available as a considerably better option than jail time or heavy fines for individuals who have been convicted of any kind of drug or alcohol related crime. As an example, a person who has been found guilty of driving while impaired of drugs or alcohol may be eligible to receive rehab services for their problem as an alternative to serving time in prison. The judge might order the individual receive rehab, either alone or as well as other sentencing. First-time offenders specifically are often given the ability to choose a criminal justice client rehab as opposed to other sentencing, and it is well-advised they make the most of it when it is an option. The idea behind criminal justice client rehabs is that it is far more effective and efficient to invest commitment into rehab than punishment. Much research has been done to find out how effective this process is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehabilitation. The signs and indicators seem quite positive, and criminal justice clients that do take part in rehab have a better chance of remaining out of the judicial system following treatment.
