Criminal justice client rehabs are available as being a considerably better option than incarceration or heavy fines for individuals who have already been convicted of any kind of drug or alcohol related crime. As an example, anyone who has been in prison for driving while impaired of drugs or alcohol may be eligible to obtain treatment services for their problem instead of serving time in jail. The judge might even order that the individual receive rehab, either alone or along with other sentencing. First time offenders in particular are often given the opportunity to choose a criminal justice client rehab instead of other sentencing, and it is highly recommended they reap the benefits of it when it is an alternative. The concept behind criminal justice client rehabs is that it is far more effective and efficient to invest effort and time into treatment than punishment. Much research has been completed to find out how effective this process is on recidivism rates, i.e. if the individual returns or not to criminal justice system following treatment. All indicators seem to be quite positive, and criminal justice clients who take part in rehabilitation have better possibility of remaining out of the system following treatment.
