Criminal justice client rehabs can be considered like a considerably better option than time in jail or significant fines for individuals who have already been convicted of any type of alcohol or drug related crime. For instance, someone who has been in prison for driving while impaired of alcohol or drugs may qualify to obtain rehab services because of their problem as an alternative to serving time in jail. The judge might order that the individual receive rehabilitation, either alone or together with other consequences. First-time offenders specifically are often given the opportunity choose a criminal justice client rehab rather than other sentencing, and it is highly recommended that they benefit from it if it is a possibility. The concept behind criminal justice client rehabs is it is way more efficient and effective to invest time and energy into rehab than punishment. Much research has been done to see how effective this approach is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehab. The signs and indicators appear to be quite positive, and criminal justice clients who take part in rehab have better chance of remaining out of the judicial system following rehab.
