Criminal justice client rehabs are available being a considerably better option than prison time or significant fines for many who have been convicted of any type of drug or alcohol related crime. As an example, someone who has been found guilty of driving drunk of alcohol or drugs may be eligible to obtain rehab services because of their problem as an alternative to serving time in jail. The judge might order that the individual receive rehabilitation, either alone or in addition to other consequences. First-time offenders specifically are often given the opportunity to choose a criminal justice client rehab rather than other sentencing, and it is highly recommended they make the most of it if it is an alternative. The theory behind criminal justice client rehabs is that it is much more efficient and effective to invest commitment into rehabilitation than punishment. Much research has been done to see 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 take part in rehabilitation have better chance of remaining out of the system following rehabilitation.
