Criminal justice client rehabs are available as being a significantly better option than incarceration or significant fines for individuals who have been convicted of any kind of drug or alcohol related crime. For example, someone who has been found guilty of driving under the influence of alcohol or drugs may be eligible for rehab services for their problem instead of serving time in prison. The judge might even order the individual receive rehabilitation, either alone or as well as other sentencing. First-time offenders specifically in many cases are given the opportunity to pick a criminal justice client rehab instead of other sentencing, and it is highly recommended that they take advantage of it if it is a possibility. The idea behind criminal justice client rehabs is it is way more efficient and effective to invest time and energy into treatment than enforcement of other consequences. Much research has been carried out 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 to be quite positive, and criminal justice clients who do experience rehab have a much better probability of remaining out of the system after treatment.
