Criminal justice client rehabs can be considered as being a considerably better option than time in jail or significant fines for many who have already been convicted of any type of alcohol or drug related crime. For example, anyone who has been in prison for driving while impaired of drugs or alcohol may qualify to obtain rehab services for problem rather than serving time in prison. The judge may even order that the individual receive rehabilitation, either alone or along with other consequences. First-time offenders specifically tend to be given the opportunity to pick a criminal justice client rehab rather than other sentencing, and it is highly recommended that they make the most of it when it is a choice. The theory 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 carried out to discover how effective this process is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehab. All indicators appear to be quite positive, and criminal justice clients that do experience rehabilitation have a better chance of remaining out of the system following rehab.
