Criminal justice client rehabs are available being a considerably better option than incarceration or heavy fines for many who have already been convicted of any kind of drug or alcohol related crime. By way of example, a person who has been in prison for driving drunk of drugs or alcohol may qualify to get rehab services for problem as an alternative to serving time in jail. The judge might order that the individual receive rehabilitation, either alone or along with other sentencing. First-time offenders in particular tend to be given the ability to choose a criminal justice client rehab rather than other sentencing, and it is highly recommended they take advantage of it if it is an option. The theory behind criminal justice client rehabs is it is much more efficient and effective to invest commitment into rehab than enforcement of other consequences. Much research has been done to observe 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 experience treatment have a better chance of remaining out of the system following treatment.
