Criminal justice client rehabs can be considered as being a far better option than prison time or heavy fines for individuals who have already been convicted of any type of drug or alcohol related crime. For instance, someone who has been in prison for driving while impaired of alcohol or drugs may qualify to obtain rehab services for their problem as opposed to serving time in prison. The judge may even order that the individual receive treatment, either alone or along with other consequences. New offenders specifically in many cases are given the opportunity to go with a criminal justice client rehab instead of other sentencing, and it is highly recommended they reap the benefits of it if it is an option. The theory behind criminal justice client rehabs is that it is way more effective and efficient to invest effort and time into treatment than punishment. Much research has been completed to find out how effective this strategy is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehabilitation. All indicators seem to be quite positive, and criminal justice clients who do take part in rehab have a better chance of remaining out of the system after rehabilitation.
