Criminal justice client rehabs are available as being a significantly better option than prison time or significant fines for many who have already been convicted of any kind of drug or alcohol related crime. As an example, someone who has been in prison for driving under the influence of drugs or alcohol may be eligible to receive rehab services because of their problem instead of serving time in prison. The judge may even order that the individual receive rehabilitation, either alone or along with other consequences. Very first time offenders in particular are often given the opportunity pick a criminal justice client rehab as an alternative to 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 much more efficient and effective to invest effort and time into rehab than punishment. Much research has been done to observe how effective this strategy is on recidivism rates, i.e. if the individual returns or not to criminal justice system following treatment. The signs and indicators appear to be quite positive, and criminal justice clients who do take part in rehabilitation have a better potential for remaining out of the judicial system after treatment.
