Criminal justice client rehabs are available being a considerably better option than incarceration or heavy fines for those who have already been convicted of any kind of drug or alcohol related crime. By way of example, anyone who has been in prison for driving under the influence of drugs or alcohol may qualify to obtain treatment services for their problem as an alternative to serving time in jail. The judge might even order the individual receive rehab, either alone or together with other sentencing. Very first time offenders specifically tend to be given the chance to select a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended they take advantage of it if it is a possibility. The idea 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 done to discover how effective this process is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehabilitation. The signs and indicators appear to be quite positive, and criminal justice clients that take part in rehab have a better possibility of remaining out of the judicial system after rehab.
