Criminal justice client rehabs are available like a far better option than prison time or significant fines for many who have already been convicted of any sort of drug or alcohol related crime. For example, a person who has been found guilty of dui of drugs or alcohol may be eligible for rehabilitation services for his or her problem instead of serving time in jail. The judge may even order that the individual receive rehab, either alone or along with other sentencing. First time offenders in particular in many cases are given the opportunity to go with a criminal justice client rehab rather than other sentencing, and it is well-advised they benefit from it if it is an option. The concept behind criminal justice client rehabs is it is way more effective and efficient to invest time and effort into rehab than punishment. Much research has been done to see how effective this process is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehab. The signs and indicators seem to be quite positive, and criminal justice clients who take part in rehab have a better possibility of remaining out of the judicial system following rehabilitation.
