Criminal justice client rehabs can be considered like a significantly better option than jail time or heavy fines for many who have already been convicted of any sort of drug or alcohol related crime. For instance, a person who has been found guilty of driving while impaired of drugs or alcohol may qualify to receive rehabilitation services for his or her problem rather than serving time in prison. The judge may even order that the individual receive rehab, either alone or in addition to other consequences. First-time offenders in particular in many cases are given the opportunity to pick a criminal justice client rehab rather than other sentencing, and it is highly recommended they make the most of it if it is a possibility. The theory behind criminal justice client rehabs is it is way more effective and efficient to invest effort and time into rehab than punishment. Much research has been done to discover how effective this method is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehabilitation. All indicators appear to be quite positive, and criminal justice clients who do take part in rehabilitation have a much better possibility of remaining out of the system following treatment.
