Criminal justice client rehabs can be considered as being a significantly better option than time in jail or significant fines for those who have already been convicted of any type of alcohol or drug related crime. For example, anyone who has been found guilty of dui of alcohol or drugs may be eligible to receive treatment services for problem instead of serving time in jail. The judge may even order the individual receive rehab, either alone or along with other sentencing. Very first time offenders specifically are often given the ability to go with a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended that they take advantage of it if it is a choice. 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 individual returns or not to criminal justice system following rehabilitation. The signs and indicators appear to be quite positive, and criminal justice clients who do take part in rehabilitation have a better probability of remaining out of the system following treatment.
