Criminal justice client rehabs are available as a considerably better option than prison time or significant fines for many who have already been convicted of any type of drug or alcohol related crime. For example, somebody who has been found guilty of driving while impaired of drugs or alcohol may qualify to receive rehabilitation services for their problem rather than serving time in jail. The judge might even order the individual receive rehab, either alone or in addition to other consequences. First-time offenders specifically in many cases are given the opportunity choose a criminal justice client rehab as opposed to other sentencing, and it is highly recommended they make the most of it when it is a possibility. The idea behind criminal justice client rehabs is 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 individual returns or not to criminal justice system following rehab. The signs and indicators appear to be quite positive, and criminal justice clients who do experience rehab have better chance of remaining out of the system after rehab.
