Criminal justice client rehabs are available as being a significantly better option than prison time or significant fines for individuals who have already been convicted of any sort of drug or alcohol related crime. As an example, someone who has been found guilty of driving while impaired of alcohol or drugs may be eligible to obtain rehab services for their problem as an alternative to serving time in jail. The judge could even order the individual receive treatment, either alone or in addition to other sentencing. First time offenders in particular tend to be given the opportunity select a criminal justice client rehab rather than other sentencing, and it is highly recommended they take advantage of it if it is an option. The theory behind criminal justice client rehabs is it is way more effective and efficient to invest time and effort into rehabilitation than punishment. Much research has been completed to see how effective this method is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehab. The signs and indicators seem quite positive, and criminal justice clients who do take part in rehab have better probability of remaining out of the judicial system after treatment.
