Criminal justice client rehabs can be considered like a considerably better option than prison time or significant fines for individuals who have already been convicted of any type 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 get rehabilitation services for his or her problem as opposed to serving time in jail. The judge could even order that the individual receive rehab, either alone or together with other sentencing. First-time offenders specifically are often given the ability to choose a criminal justice client rehab instead of other sentencing, and it is highly recommended that they make the most of it if it is an option. The theory behind criminal justice client rehabs is it is way more efficient and effective to invest effort and time into rehab than punishment. Much research has been completed to see how effective this approach is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following treatment. The signs and indicators seem to be quite positive, and criminal justice clients that do experience treatment have a much better chance of remaining out of the system after treatment.
