Criminal justice client rehabs are available as being a significantly better option than time in jail or significant fines for many who have already been convicted of any sort of drug or alcohol related crime. For instance, someone who has been found guilty of driving drunk of drugs or alcohol may be eligible for rehab services for problem as opposed to serving time in jail. The judge could even order that the individual receive rehabilitation, either alone or as well as other sentencing. First-time offenders specifically will often be given the ability to choose a criminal justice client rehab rather than other sentencing, and it is highly recommended that they make the most of it if it is an option. The concept behind criminal justice client rehabs is that it is much more efficient and effective to invest time and energy into rehab than punishment. Much research has been carried out 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 treatment. The signs and indicators appear to be quite positive, and criminal justice clients that do take part in rehab have a much better probability of remaining out of the judicial system following rehabilitation.
