Criminal justice client rehabs are available as being a significantly better option than prison time or significant fines for those who have already been convicted of any sort of alcohol or drug related crime. For instance, somebody who has been found guilty of driving drunk of alcohol or drugs may qualify to receive rehab services for problem instead of serving time in jail. The judge may even order that the individual receive treatment, either alone or as well as other consequences. First-time offenders specifically will often be given the ability to go with a criminal justice client rehab rather than other sentencing, and it is well-advised that they make the most of it when it is a possibility. The theory behind criminal justice client rehabs is that it is far 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 process 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 who do experience rehab have better probability of remaining out of the system following rehabilitation.
